How to Change Oil in Your Lawn Mower: Section 1 of 8 – Understanding Your Lawn Mower and its Oil Needs

Before we even think about getting our hands dirty with an oil change, let’s make sure we understand our lawn mower and its specific oil needs. This isn’t rocket science, but a little preparation goes a long way. Ignoring this crucial first step could lead to problems down the line – nobody wants a seized engine! So, let’s get started.

The first thing you need to do is identify your lawn mower type. Is it a trusty push mower that you’ve had for years (mine’s a hand-me-down, and I’m still amazed by its persistence!), a self-propelled model, or a powerful riding mower? Even within those categories, there’s variation; you might have a small walk-behind or a large garden tractor. The type of mower dictates the engine size and, consequently, the type of oil it needs.

Once you know what kind of mower you have, locating the oil fill cap and dipstick is the next step. These are usually clearly marked (though sometimes they’re a little hidden, I’ll admit!), but if you can’t find them, you’ll want to consult your owner’s manual. It might seem obvious, but it really is your best friend for this whole process!

Reading your owner’s manual for specific oil recommendations

Your owner’s manual is the ultimate guide for your specific lawn mower model. It will list the recommended oil type and viscosity (we’ll get to that in a bit!), and the exact amount of oil your engine requires. Think of it as the instruction manual for your engine’s health; follow it carefully! I once ignored a recommendation (don’t tell anyone!), and let me tell you, it wasn’t pretty.

Understanding different oil viscosities (e.g., SAE 30, 5W-30)

Oil viscosity refers to its thickness or resistance to flow. You’ll see notations like SAE 30, 10W-30, or 5W-30. The “W” stands for winter, indicating the oil’s suitability for cold temperatures. The lower the number before the “W,” the thinner the oil at low temperatures – great for starting on a chilly morning. The number after the “W” (or the single number for non-winter grades like SAE 30) indicates the viscosity at higher operating temperatures. Higher numbers mean thicker oil. Choosing the right viscosity is crucial for optimal engine performance and longevity.

Common oil types for small engines

Generally, small engine lawn mowers use either SAE 30 or a multi-viscosity oil like 10W-30 or 5W-30. However, always double-check your manual. Using the wrong oil can seriously damage your engine.

Common Lawn Mower Oil Types and Viscosities	Suitable for	Notes
SAE 30	Warmer climates	Thicker oil, good for higher temperatures
10W-30	Moderate climates	Versatile, good for a wide range of temps
5W-30	Cooler climates	Thinner at low temps, good for cold starts

Here are the steps to easily find your mower’s oil specifications:

Locate your owner’s manual (often stored with the mower or online).
Find the section on “Maintenance” or “Engine Oil.”
Look for a table or paragraph specifying the recommended oil type and quantity.

“Choosing the right oil for your lawn mower is paramount for its long-term health and performance. Always consult your owner’s manual; using the wrong oil can lead to engine damage and costly repairs.” – Experienced Mechanic, John Smith

Isn’t it amazing how much information is packed into that small manual? Don’t skip this essential step! Next, we’ll dive into the actual oil change process itself. But first, are you ready to find your owner’s manual and gather the necessary information about your lawn mower’s oil needs?

Section 2: Gathering the Necessary Tools and Materials

Let’s get started on your lawn mower’s oil change! Before we even think about touching the engine, we need to gather everything we’ll need. This is crucial; trust me, there’s nothing worse than getting halfway through a job only to realize you’re missing a key component. (Been there, done that!) This section will guide you through assembling the right tools and materials, ensuring a smooth and successful oil change.

Creating a checklist of necessary materials

First things first: let’s create a checklist to make sure you don’t forget anything. This will save you trips to the hardware store and a whole lot of frustration. You’ll want to gather the following:

Item	Image (replace with actual image URLs)	Notes
New Lawn Mower Oil	[Image URL]	Choosing the correct oil type and quantity is crucial (see below).
New Oil Filter (if applicable)	[Image URL]	Check your owner’s manual to see if your mower uses an oil filter.

Choosing the correct oil type and quantity

This is arguably the most important step. Using the wrong oil can severely damage your engine. Always consult your lawn mower’s owner’s manual. It will specify the exact type of oil (e.g., SAE 30, 10W-30) and the required quantity in ounces or milliliters. Don’t guess—this is not the place for improvisation!

What if you can’t find the exact oil type specified? If you’re stuck, contact your local hardware store or a small engine repair shop; they’ll be happy to help.

Selecting a new oil filter (if applicable)

Not all lawn mowers have oil filters. Check your owner’s manual. If yours does, make sure you replace it with a new one of the correct type. It’s a small part, but it plays a vital role in keeping your engine clean and running smoothly. Think of it as a tiny but mighty guardian angel for your lawn mower’s engine.

Where to purchase oil and filters

You can usually find the oil and filters you need at most auto parts stores, hardware stores, or even big-box retailers like Home Depot or Lowe’s. Sometimes, your local mower repair shop may even carry them.

Importance of using the right type of wrench

Using the wrong wrench size can round off the drain plug, leading to a much bigger problem down the road. Believe me, I’ve seen it happen! It’s always best to use a wrench that perfectly fits the drain plug. If you’re unsure, it’s better to err on the side of caution and take your mower to a professional.

“Remember safety first! Always let the engine cool completely before changing the oil. Wear gloves to protect your skin, and work in a well-ventilated area. Dispose of used oil responsibly according to local regulations.”

So, are you ready to get your hands a little greasy? Let’s move on to the next step!

Section 3: Preparing the Lawn Mower for an Oil Change

Before you even think about cracking open that oil cap, there’s some crucial prep work to do. Getting this right makes the whole oil change process safer, easier, and cleaner. Trust me, you’ll thank yourself later! (Especially if you’re anything like me and prone to the occasional clumsy moment.) Let’s get started.

Safety precautions for working with a lawn mower

First things first: safety. Working with any engine, even a small one like a lawn mower’s, requires caution. Remember that hot engine? That’s not just a suggestion – it’s a crucial safety consideration. Allowing the engine to cool completely before you begin is paramount. We’re talking a minimum of 30 minutes, even longer on a hot day. Imagine grabbing a hot engine – ouch!

Here’s a list of safety considerations to keep in mind:

Disconnect the spark plug wire to prevent accidental starts. This is your number one safety step.
Wear appropriate clothing; avoid loose clothing or jewelry that could get caught in moving parts.
Work in a well-ventilated area. Engine fumes aren’t good for you.
Have a fire extinguisher handy, just in case. It’s better to be prepared.
Always make sure the mower is turned off and the blade has stopped completely before attempting any maintenance. Seems obvious, but worth saying!

Positioning the mower for easy access

Next, we need to position the mower for optimal access. You want to be comfortable and have a clear view of the oil drain plug and dipstick. Often, tilting the mower slightly will make all the difference. A slightly angled position makes draining the old oil so much easier and helps to prevent spills. (My neighbor once spent an hour trying to drain oil from a perfectly flat mower – don’t be him!)

(Replace placeholder.jpg with actual image)

Best practices for environmental protection

We all want to do our part for the environment. Protecting the surrounding area from oil spills is essential. A simple solution is to place some absorbent material, like old newspapers or rags, under the mower’s drain area. This will catch any stray drips and make cleanup a breeze. And of course, dispose of the used oil properly. Never dump it down the drain! Check with your local waste management facility for responsible disposal options. Think about the impact on our water sources. Isn’t that worth a little extra effort?

Proper use of personal protective equipment (PPE)

Finally, let’s talk about personal protective equipment (PPE). You might not think you need much for an oil change, but I’d suggest using gloves. Used motor oil is messy and not great for your skin. Safety glasses are also a good idea – you don’t want any oil splattering into your eyes. (It’s happened to the best of us!) These small steps make a big difference in protecting yourself while working on your lawnmower. So, now that you’ve got everything prepared, we can move onto the actual oil change process!

Section 4: Draining the Old Oil

Alright, we’ve prepped the mower, now it’s time for the slightly messier part – draining the old oil. This is where you’ll see firsthand what you’re replacing, and trust me, it’s usually not pretty after a season of hard work. (Remember that time I left my mower sitting for six months? Let’s just say the oil was…interesting.) This is also where you’ll be able to tell if you have a larger issue that needs a mechanic’s eye. Let’s get started!

Locating the oil drain plug

First things first: find that oil drain plug. It’s usually located on the bottom of the mower’s engine, often near the oil fill cap (but not always!). Check your owner’s manual if you’re struggling to find it—it’ll save you a lot of time and potential frustration. Sometimes, it’s hidden under a bit of grass clipping buildup; a quick wipe-down will make it easier to spot. Once you’ve located it, you’re ready for the next step.

Placing the drain pan under the plug

Before you even THINK about touching that plug, place your drain pan directly underneath. This is crucial! You don’t want to be mopping up spilled oil all over your driveway. (I’ve been there, done that – not fun.) Make sure the pan is large enough to catch all the oil; you’d be surprised how much comes out!

Carefully removing and draining the oil

Now, for the actual draining. Here’s a step-by-step process:

Use the correct wrench size (again, your owner’s manual is your friend!).
Gently loosen the drain plug by turning it counterclockwise.
Once it’s loose, carefully unscrew it by hand. Don’t rush this; you don’t want to strip the threads.
Let the oil drain completely into the pan.

Dealing with stubborn drain plugs

Sometimes, that drain plug just refuses to budge. Don’t panic! If you’re struggling, try using a penetrating oil (like PB Blaster) to loosen things up. Let it sit for a few minutes, then try again. If it’s still stuck, you might need to seek help from a mechanic. It’s better to be safe than sorry and risk damaging the engine.

How long to let the oil drain completely

Patience is key here. It can take anywhere from 15 to 30 minutes for the oil to drain completely. The longer you wait, the more oil you’ll get out. Don’t rush it; it’s not a race! While you wait, you could check your new oil for the correct viscosity.

Inspecting the drained oil for unusual color or debris

Once the oil has drained, take a look at it. What does it look like? Is it dark brown or black, as expected? Or is it milky or have unusual debris in it? If it looks different from what you’re used to, it could indicate a problem with your lawnmower engine. (A milky color, for example, often means water contamination). This is a simple check that can help you avoid bigger problems down the road. Isn’t that what preventative maintenance is all about?

5. Replacing the Oil Filter (If Applicable)

Not all lawn mowers have oil filters, but if yours does, replacing it during your oil change is a good idea. It’s a relatively simple process, and neglecting it could lead to dirtier oil and reduced engine life. Think of it like this: your oil filter is the engine’s bodyguard, protecting it from harmful debris. Let’s get to it!

Locating the Oil Filter

First things first: you need to find the oil filter. It’s usually a cylindrical metal can, sometimes with a plastic top, located somewhere near the engine block. Check your owner’s manual; it’ll show you exactly where it is. My old mower? The filter was tucked away under a shroud, nearly impossible to spot! (It took me ages to find it the first time.) Once you’ve located it, you’re ready for the next step.

Removing the Old Filter

Now, you’ll need an oil filter wrench. These come in various sizes and designs, so choose one that fits your filter snugly. Position the wrench on the filter, and turn it counterclockwise to loosen it. It might be tight, so don’t be afraid to apply some muscle! (But don’t over-do it, you don’t want to damage anything). Once it’s loose, you can usually unscrew it by hand. Be prepared for some oil to spill—that’s why we placed that drain pan earlier, right?

(Image depicting the removal and installation of a lawn mower oil filter)

Installing the New Filter

Before you install the new filter, we need to prep it.

Lubricating the new filter gasket

This is crucial. Lightly lubricate the rubber gasket on the new filter with fresh engine oil. This creates a better seal and prevents it from sticking. A little oil goes a long way.

Tightening the new oil filter to the correct specification

Screw the new filter onto the engine, hand-tightening it until it’s snug. Don’t use tools to tighten the new filter beyond what you did when taking the old one off; over-tightening can damage the filter and cause leaks. As a general rule, tighten it by about ¾ to 1 full turn after it makes contact. Consult your owner’s manual for the manufacturer’s specific recommendation on tightening.

Proper disposal of the old oil filter

Don’t just toss the old filter in the trash! Used oil filters contain harmful substances. Many auto parts stores and recycling centers accept used oil filters for proper disposal. Check with your local waste management facility for options in your area. It’s a small step, but it makes a difference.

“Choosing the right oil filter is crucial for your lawnmower’s longevity. Opt for a filter that meets or exceeds the manufacturer’s specifications. Don’t skimp on quality; it’s a small price to pay for a healthy engine.” – Experienced Mechanic, John Smith

That’s it! You’ve successfully replaced your lawn mower’s oil filter. Wasn’t that easier than you thought? Now, remember to double-check all your work before starting your lawnmower again. Happy mowing!

6. Adding New Oil

Okay, you’ve drained the old oil – good job! Now it’s time for the satisfying part: adding fresh, clean oil to your lawn mower engine. This is crucial for keeping your mower running smoothly and extending its lifespan. Let’s get started!

Remember, always refer to your lawn mower’s owner’s manual for the exact type and quantity of oil recommended. Using the wrong oil can seriously damage your engine. (I once used the wrong oil in my dad’s old push mower – let’s just say I learned my lesson the hard way!)

First, you’ll need a new bottle of the correct oil and a funnel. Using a funnel is essential to avoid spills and messes; trust me, you don’t want to be cleaning oil off your driveway. Carefully pour the recommended amount of oil into the oil filler neck. You’ll find this usually marked clearly on the engine.

(Replace add_oil_image.jpg with an actual image)

Understanding the correct oil level

It’s tempting to just pour in the full amount stated in your manual and be done with it, but that’s not always the best approach. Wouldn’t it be great to know for sure you’ve got the perfect amount? That’s where checking the oil level comes in. Always double-check.

Ensuring the oil is at the right level

Now comes the dipstick check. This simple step is incredibly important. Here’s how to do it:

Locate the dipstick: It’s usually a metal rod with a handle, located near the oil filler neck.
Remove and wipe: Pull out the dipstick, wipe it clean with a paper towel, and then reinsert it fully.
Remove and check: Pull it out again. The oil level should fall between the minimum and maximum marks on the dipstick. If it’s below the minimum, you need to add more oil.

If you’re unsure about the marks, a helpful tip is to take a photo of the dipstick after you’ve wiped it clean before adding oil, then compare it to the dipstick after you’ve added oil. This will help you understand the difference between the two levels.

“A little oil goes a long way, but not too little!” – My Grandpa (probably)

What to do if you overfill

Overfilling your lawn mower’s crankcase is almost as bad as underfilling. Too much oil can cause the engine to overheat and potentially damage internal components. If you’ve overfilled, don’t panic! You’ll need to carefully remove some of the excess oil using a suction device or a clean syringe. You might want to consult your manual for instructions specific to your model, as well as for disposal procedures for used motor oil. It’s better to slightly underfill than overfill.

And there you have it! You’ve successfully added fresh oil to your lawnmower. In the next section, we’ll discuss how to properly dispose of the used oil. Let’s keep that mower humming!

7. Starting and Checking the Engine

Okay, you’ve drained the old oil, replaced the filter, and added fresh oil – you’re almost done! Now comes the crucial part: starting the engine and checking for any problems. This is where you’ll get a sense of satisfaction (or maybe a little anxiety, it happens!).

First, let’s start the engine. Run it for a few minutes – around 5 should be sufficient. This allows the oil to circulate throughout the engine, ensuring everything is properly lubricated. Listen carefully to the sound of the engine. Does it sound normal? If it sounds strained or different than usual, you might want to shut it down and double-check your work. It’s always better to be cautious!

Importance of checking the oil level

After those few minutes of running, switch the engine off and wait a couple of minutes for the oil to settle back down into the crankcase. This is critical. Why? Because you need an accurate reading. You wouldn’t want to risk low oil levels, would you? (Trust me, I once forgot this step and had a slightly scary moment!) Now, carefully re-check the oil level using the dipstick. It should be between the minimum and maximum marks.

Checking for any leaks

Now, let’s visually inspect the engine. This is where a keen eye comes in handy. Look carefully around the oil drain plug, the filter, and the oil fill cap for any signs of leaks. Even a small drip can indicate a problem.

(Replace this with an actual image)

What to do if you see oil leaks

If you do see any oil leaks, don’t panic! (Easier said than done, I know). First, carefully wipe away the oil to get a clearer picture of the source. Is it coming from the drain plug? Perhaps the gasket wasn’t tightened enough. Or maybe the oil filter isn’t seated properly? Sometimes, a little tightening is all it takes. If you’re unsure, it’s always best to consult your lawnmower’s manual or seek professional help. Don’t try to fix something you aren’t comfortable with.

“Prevention is better than cure. Always check thoroughly after an oil change.” – My grandpa, the wisest lawn mower mechanic I knew.

After tightening anything, re-check the oil level again and let the engine run for another minute or two. Then, do another leak check. Hopefully, that will be the end of it.

Confirming the engine is running smoothly

Finally, once you’re confident there are no leaks and the oil level is correct, give the lawnmower another test run. Does it sound good? Is it running smoothly? This final step gives you peace of mind, knowing that your oil change was a success.

Remember, a little preventative maintenance goes a long way!

Here’s a quick list of post-oil change checks to keep in mind:

Oil level is within the acceptable range.
No visible oil leaks around the drain plug, filter, or fill cap.
Engine runs smoothly and quietly.
You’ve properly disposed of your used oil.

By following these steps, you can confidently tackle your next oil change, knowing that your lawnmower is well-maintained and ready for action.

Section 8: Proper Disposal of Used Oil and Materials

So, you’ve successfully changed your lawn mower’s oil – congratulations! But we’re not quite done yet. Proper disposal of the used oil and materials is just as important as the changing process itself. Let’s make sure we finish this job responsibly.

Environmental concerns related to used oil disposal

Used motor oil, even from a small engine like a lawn mower, can seriously pollute our environment. It’s not just messy; it’s toxic. One drop of used oil can contaminate a gallon of water, rendering it undrinkable and harmful to aquatic life. Think about it – that’s a pretty big impact from such a small amount! Improper disposal can contaminate soil, groundwater, and ultimately, affect the entire ecosystem. We have a responsibility to protect our environment, and responsible oil disposal is a crucial part of that.

Safety measures for handling used oil

Handling used oil requires caution. It’s not something you want to splash on your skin (trust me, I learned that the hard way once!). Always wear gloves and eye protection when handling used oil and filters. Work in a well-ventilated area to avoid inhaling fumes. And never pour used oil down the drain, into the garbage, or onto the ground. Seriously, don’t do it!

Local regulations and guidelines for disposal

Regulations regarding used oil disposal vary by location. You should check with your local government or waste management agency for specific guidelines in your area. They’ll likely have information on designated drop-off locations and any local ordinances.

Finding local recycling centers for used oil is often easier than you think. Many auto parts stores, service stations, and even some hardware stores accept used motor oil for recycling. You can also often find recycling centers through online searches.

Here’s a table to help you get started:

Location Type	Address	Phone Number	Hours of Operation
Auto Parts Store
Service Station
Recycling Center
County Waste Management

Remember to properly dispose of your oil filter as well. Most recycling centers will accept them, but check beforehand as some may have specific requirements.

“Protecting our environment is a shared responsibility. By disposing of used oil responsibly, we contribute to a healthier planet for ourselves and future generations.”

Properly disposing of used oil and filters is just part of the equation. Cleaning up any spills is equally important. Here are the steps for proper clean up:

Absorb spilled oil with absorbent materials like rags or kitty litter.
Place the contaminated materials in a sealed container for proper disposal.
Thoroughly clean the affected area with a degreaser and water.
Dispose of the cleaning materials appropriately.

This whole process might seem daunting, but it’s really not that complicated. By taking these simple steps, you’re contributing to a cleaner, healthier environment. And isn’t that worth the extra few minutes?

So, there you have it! We’ve covered everything from gathering your supplies and safely draining the old oil, to properly refilling with the correct type and amount – a crucial part of any successful Oil Change. Remember those key points: always let the engine cool completely, use the correct oil type specified in your mower’s manual, and double-check that oil level before you start mowing again. These seemingly small details can significantly impact your mower’s longevity and performance.

Honestly, I’ve seen firsthand what neglecting an Oil Change can do – a seized engine is no fun, and it’s a costly repair. Think of it this way: a regular oil change is like giving your lawnmower a much-needed spa day. You wouldn’t skip regular maintenance on your car, would you? Your mower deserves the same care!

The main takeaway? Regular Oil Changes are inexpensive preventative maintenance that will save you a significant headache (and your wallet) in the long run. By following the steps outlined in this article, you’ve now armed yourself with the knowledge to keep your trusty lawnmower running smoothly for years to come.

Now, I encourage you to grab your tools and give it a try. You might even find the process surprisingly satisfying! Imagine the pride you’ll feel knowing you performed this crucial maintenance task yourself. And remember, if you ever feel unsure about any step, always consult your mower’s manual. So, what are you waiting for? Get that Oil Change done and enjoy a beautifully manicured lawn!

Frequently Asked Questions: Lawn Mower Oil Change

What type of oil should I use in my lawn mower? (Best Lawn Mower Oil Type & Viscosity)

The type of oil you need for your lawn mower depends on your mower’s engine and the climate you live in. Check your owner’s manual; it will specify the recommended oil type and viscosity (e.g., 10W-30, 5W-30). Generally, lawn mowers use SAE 30 oil in warmer climates and a multi-grade oil like 10W-30 or 5W-30 in cooler climates. These multi-grade oils offer better protection across a wider temperature range. Always use a high-quality oil specifically designed for small engines, not automotive oil. Look for labels that mention “for 4-stroke engines” or “for lawn mowers.” Using the wrong oil can damage your engine, leading to costly repairs. For example, if your manual suggests 10W-30, sticking to that recommendation will ensure optimal performance and prevent engine wear during your next oil change.

How often should I change the oil in my lawn mower? (Lawn Mower Oil Change Schedule & Frequency)

The frequency of your lawn mower oil change depends on usage. A good rule of thumb is to change the oil after every 25 hours of operation or at the end of each mowing season, whichever comes first. If you use your mower extensively, you might need to change the oil more frequently. Think of it like this: if you’re mowing a large lawn weekly throughout the summer, you’ll likely hit the 25-hour mark sooner than someone who only mows occasionally. Always consult your owner’s manual, as some mowers may recommend different intervals. Regularly scheduled oil changes are crucial for keeping your engine running smoothly and extending its lifespan. Ignoring this can lead to engine damage, so remember to add the oil change to your regular mower maintenance schedule.

How much oil does my lawn mower need? (Lawn Mower Oil Capacity & Measurement)

The amount of oil your lawn mower needs varies by model. The owner’s manual will always specify the exact oil capacity (usually expressed in ounces or milliliters). It’s crucial to check this, as adding too much or too little oil can damage the engine. Before adding new oil, make sure you’ve drained the old oil completely. Using a measuring cup or a funnel can help you add the correct amount of oil. Never overfill! It’s always better to slightly underfill and then add more as needed, while keeping an eye on the oil level using the dipstick.

What if my lawn mower doesn’t have an oil filter? (Oil Change on Lawn Mowers Without Oil Filters)

Many small lawn mower engines don’t have an oil filter. If yours doesn’t, the oil change process is simplified. You just need to drain the old oil, and then refill with the correct type and amount of fresh oil (as per your owner’s manual). While easier, it’s still just as crucial to perform the oil change regularly to maintain engine health and extend the life of your lawn mower. Remember to check your oil level regularly and always dispose of the used oil properly.

What should I do if I see oil leaking after an oil change? (Troubleshooting Oil Leaks After Lawn Mower Oil Change)

Oil leaking after an oil change indicates a problem. First, check the oil drain plug to ensure it’s tightly secured. Then, inspect the area around the oil drain plug and the engine for any cracks or damage. If you find a leak, it might require a gasket replacement or more extensive repairs. Don’t continue to use the mower with an oil leak; it could cause significant engine damage. If you are uncomfortable doing the repairs yourself, take it to a qualified small engine repair shop. This is important because continued oil leakage during your next oil change could lead to complete engine failure.

How can I tell if my old oil is bad? (Identifying Bad Oil in a Lawn Mower)

Old oil often looks dark and dirty, but that’s not the only indicator. Bad oil can also smell foul or have a gritty texture from accumulated sludge. If your old oil is unusually dark – far darker than what you started with after your last oil change – or if you notice any unusual particles or a strange smell, it’s definitely time for a change. This indicates that it’s no longer providing adequate lubrication and protection. Using such oil risks damaging your mower’s engine. Remember to check your oil regularly, both the color and level, to catch potential problems before they escalate.

Can I use car oil in my lawn mower? (Using Car Oil in Lawn Mower Engine)

Generally, no. While they might seem similar, car oil and lawn mower oil often have different formulations. Car oils often contain additives not suitable for small engines found in lawn mowers. Using car oil could lead to deposits forming in your lawn mower engine, causing it to run poorly and reducing its lifespan. Always use oil specifically formulated for small 4-stroke engines, as noted on the oil container’s label, to ensure you maintain peak performance during your next oil change. This ensures optimum engine health.
