Yes, you can absolutely change your own engine oil. Learning how to change your own engine oil step by step is one of the most rewarding DIY skills any vehicle owner can pick up. It takes about 30 to 45 minutes, costs roughly half what a shop charges, and gives you full control over what goes into your engine. Whether you drive a sedan, truck, or SUV, the fundamental process is the same across nearly every vehicle on the road.
Before we get into the details, here is a quick summary of the entire process. These eight steps are everything you need to do an oil change yourself:
Park on level ground, gather your tools, and warm up the engine briefly.
Lift the vehicle using a floor jack and jack stands, or drive onto ramps.
Locate the drain plug on the oil pan and place your drain pan underneath.
Remove the drain plug counterclockwise and let the old oil drain fully.
Remove the old oil filter and install the new one, lubricating the gasket first.
Reinstall the drain plug with a new crush washer and lower the vehicle.
Pour new motor oil into the engine through the oil fill cap using a funnel.
Check the dipstick, start the engine, and inspect for leaks.
That is the whole job. The rest of this guide walks you through each step in detail, with tips I have learned from doing this dozens of times on everything from compact cars to heavy-duty trucks. If you are also doing regular maintenance like oil changes on other gas-powered equipment, the same principles apply across the board.

Having the right tools ready before you start makes the difference between a smooth 30-minute job and a frustrating afternoon. Here is the complete list of what you will need.
You will need a way to lift the front of the vehicle. This means either a floor jack and pair of jack stands (rated for your vehicle's weight), or a set of vehicle ramps. Ramps are actually easier and safer for beginners since you simply drive onto them with no lifting required.
A socket wrench set or combination wrench is needed to remove the drain plug. The size varies by vehicle, but common sizes are 13mm, 14mm, 15mm, or 17mm for metric vehicles, and 13mm, 15mm, or 1/2-inch for standard. Check your owner's manual or search online for your specific make and model.
An oil filter wrench helps remove a tight old filter. Not every filter needs one, but when a filter is stuck, this tool saves the day. Some DIYers prefer a strap-style wrench, others use a cap-style wrench that fits on the end of a socket extension.
An oil drain pan catches the old oil. Look for one with a spout and a lid so you can easily transport the used oil for recycling. A standard 5-quart or larger drain pan works for most vehicles.
A funnel keeps new oil from spilling down the side of the engine. A basic automotive funnel costs a few dollars and prevents messy cleanup.
Wear nitrile gloves to protect your hands from used motor oil, which contains contaminants you do not want on your skin. Keep some shop rags or paper towels nearby for wiping the dipstick and cleaning up small spills.
You need the correct amount and type of motor oil for your vehicle. Most cars take between 4 and 8 quarts, but this varies widely. Check your owner's manual for the exact oil capacity and the recommended viscosity grade (such as 0W-20, 5W-30, or 10W-30).
You also need a new oil filter matched to your vehicle. Filters are not universal, so look up the correct part number for your make, model, and year. Many auto parts stores will look this up for you if you are unsure.
Some vehicles use a crush washer on the drain plug that should be replaced at each oil change. These are inexpensive, typically under a dollar, and they create a seal that prevents leaks. Check whether your vehicle uses one, and buy a small pack to keep on hand.
Working under a vehicle carries real risk if you cut corners on safety. Following a few simple rules keeps the job safe and straightforward.
Never get under a vehicle supported only by a hydraulic jack. Jacks can fail or slowly leak pressure. Always place jack stands under the manufacturer-recommended lift points before getting underneath. If you are using ramps, make sure the wheels are chocked and the parking brake is engaged.
Park on level, solid ground. A concrete driveway or garage floor is ideal. Gravel, grass, or a slope makes the vehicle unstable and the oil drain uneven.
Let the engine cool for at least 10 minutes before draining the oil if you warmed it up. Hot oil drains faster and carries out more contaminants, but it can also burn you. If you choose to drain warm oil, wear gloves and avoid touching hot exhaust components.
Keep children and pets away from your work area. Used motor oil is toxic, and the underside of a recently running vehicle has extremely hot surfaces.
Now we get to the core of the guide. Follow these eight steps in order, and you will complete a proper oil change on your own. I have broken each step down with specific details so that even a first-timer can follow along without confusion.
Start by parking on flat, level ground. Engage the parking brake and put the car in park (or in gear if it is a manual transmission). Pop the hood and locate the oil fill cap and the dipstick so you know where they are when it is time to add fresh oil.
Run the engine for about 3 to 5 minutes to warm up the oil. Warm oil flows more freely and drains faster, and it carries more suspended contaminants out with it. Do not let the engine get fully hot, or the oil and exhaust components will be dangerously hot to handle.
While the engine warms up, lay out all your tools within arm's reach. Position your drain pan, gloves, wrench, and new filter where you can grab them without crawling out from under the car repeatedly.
Gather your new oil, new filter, and any replacement crush washers. Double-check that you have the correct viscosity grade and the right number of quarts for your engine's oil capacity.
You have two main options for getting under the car: jack stands or ramps. Both are perfectly safe when used correctly.
Using a floor jack and jack stands: Consult your owner's manual for the designated lift points on your vehicle. Place the floor jack under the reinforced lifting point and raise the vehicle until the front wheels are a few inches off the ground. Slide jack stands under the support points and slowly lower the jack until the vehicle rests securely on the stands. Give the car a gentle shake to confirm it is stable before getting underneath.
Using ramps (easier for beginners): This is my preferred method for oil changes because it requires zero lifting. Position a pair of ramps in front of your front tires. Slowly drive forward onto the ramps until the wheels settle into the grooves at the top. Have someone guide you, or check your progress through the side mirrors. Once the car is settled, engage the parking brake and place wheel chocks behind the rear tires for extra safety.
Ramps are a favorite in the DIY community. Many Reddit users in r/MechanicAdvice and r/cars specifically recommend ramps for beginners because they eliminate the risk of a jack failing. A set of quality ramps costs around $25 to $40 and lasts a lifetime.
Whichever method you use, do not skip the stability check. Shake the vehicle gently before committing to crawling underneath it.
Slide under the front of the vehicle and locate the oil pan, which is a metal pan bolted to the bottom of the engine. The drain plug is a single bolt at the lowest point or on the side of the oil pan. It is typically facing the rear or side of the engine bay.
Some vehicles have an undertray or splash shield covering the bottom of the engine. If yours does, you will need to remove a few fasteners or clips to access the drain plug and oil filter. Keep track of the hardware so reinstallation goes smoothly.
Once you spot the drain plug, position your oil drain pan directly beneath it. Account for the fact that oil will flow out at an angle initially, so place the pan slightly toward the direction the oil will travel. A pro tip: place a piece of cardboard under the drain pan to catch any splashes and protect your driveway.
Use your socket wrench to loosen the drain plug by turning it counterclockwise. Loosen it most of the way by hand once it is free, but leave it barely threaded in for now. This way, when you are ready, you can quickly pull it out and avoid getting a stream of oil on your hand.
Position your arm so it is clear of the oil stream. Quickly unscrew the drain plug the rest of the way and pull it out. The oil will flow out immediately, so be ready.
Let the oil drain fully. This usually takes 5 to 10 minutes. The flow will start as a steady stream and gradually reduce to a slow trickle. Waiting until it is just dripping ensures you get the most old oil out of the crankcase.
While the oil drains, inspect the drain plug and its gasket. The crush washer is a small metal or rubber ring that sits between the plug and the oil pan. If it looks flattened, cracked, or worn, replace it with a new one. Many mechanics recommend replacing the crush washer at every oil change to maintain a proper seal.
Once the oil has slowed to a occasional drip, you are ready to move on. Wipe the drain plug clean with a rag while you wait.
Locate your oil filter. It is a cylindrical canister, usually 3 to 5 inches long, screwed onto the side or bottom of the engine. On some vehicles, it is easily accessible from under the car. On others, you may need to reach in from above through the engine bay.
Use your oil filter wrench to loosen the old filter by turning it counterclockwise. Once it is loose, unscrew it the rest of the way by hand. Some oil will spill out of the filter as you remove it, so keep your drain pan underneath.
What if the oil filter is stuck? This is one of the most common frustrations for beginners. If the filter will not budge even with a wrench, try these techniques. First, make sure you are turning it counterclockwise, which is the loosening direction. Second, try a strap wrench for better grip. Third, if the filter is completely seized, you can carefully drive a long screwdriver straight through the side of the filter and use it as a lever to twist the filter off. This is a last resort, but it works when nothing else does.
Before installing the new filter, take a small amount of fresh oil on your finger and lubricate the rubber gasket on the top of the new filter. This prevents the gasket from binding and tearing when you tighten it, and it ensures a good seal.
Screw the new filter on by hand. Turn it clockwise until the gasket contacts the engine surface, then tighten it about three-quarters to one full turn by hand. This is what mechanics mean by "hand tight." The goal is snug enough to seal but not so tight that you need a wrench to remove it next time. Overtightening the filter is a very common beginner mistake and makes the next oil change far more difficult.
If your filter came with specific tightening instructions on the box, follow those instead. Some manufacturers specify a torque value measured in foot-pounds, but most DIYers simply go by the hand-tight rule.
Thread the drain plug back into the oil pan by hand first to avoid cross-threading. Once it is seated finger-tight, use your socket wrench to snug it down. You do not need to crank on it with full force. A common rule of thumb is about one-quarter to one-half turn past finger-tight with the wrench.
Overtightening the drain plug can strip the threads in the oil pan, which is an expensive repair. If your vehicle uses a crush washer, the washer compresses to create the seal, so there is no need for excessive torque.
Once the drain plug is secure, double-check that the new oil filter is properly installed and the old filter is out of the way. Then, if you used jack stands, raise the vehicle slightly with the floor jack, remove the stands, and lower the car to the ground. If you used ramps, simply back the car off slowly.
Open the hood and remove the oil fill cap. It is usually marked with an oil can symbol and is located on top of the engine valve cover. Place a funnel in the opening to prevent spills.
Pour in the correct amount of motor oil based on your engine's oil capacity. Check your owner's manual for the exact figure. Pour most of the oil in, then stop about a half-quart short of the total capacity. This leaves room for the level to settle so you can top it off precisely.
Use the type of oil recommended by your manufacturer. The viscosity grade (such as 5W-30, 0W-20, or 10W-30) is printed on the oil cap in many vehicles and in the owner's manual. Using the wrong viscosity can affect fuel economy, engine wear, and warranty coverage.
Replace the oil fill cap once you have finished pouring. Make sure it is secure, as a loose cap can cause oil vapors to escape and trigger a check engine light.
Wait about one minute for the new oil to drain down into the oil pan, then pull out the dipstick. Wipe it clean with a rag, reinsert it fully, and pull it out again. The oil level should be between the "full" and "add" marks on the dipstick.
If the level is low, add a small amount of oil (about a quarter of a quart) and recheck. If it is over the full mark, you have overfilled. Overfilling can cause the crankshaft to whip the oil into a froth, reducing lubrication. If this happens, you will need to drain a small amount back out.
Start the engine and let it run for about 30 seconds. This circulates oil through the new filter and pressurizes the system. Turn the engine off, wait a minute, and check the dipstick one more time. The filter absorbs some oil, so the level may drop slightly.
Finally, slide under the car or look from above with a flashlight and check around the drain plug and oil filter for any signs of leaking. If you see drips, tighten the drain plug or filter slightly and recheck. A small seep is normal on some filters immediately after installation, but it should stop within a minute.
Most oil change problems come from a handful of common mistakes. Here are the ones I see new DIYers make over and over again, and how to avoid each one.
Overfilling the oil. Pouring in too much oil is worse than slightly underfilling. Excess oil gets whipped into foam by the crankshaft, which means air bubbles reduce lubrication. Always check the dipstick and top off gradually rather than dumping in the full capacity at once.
Forgetting the crush washer. If your vehicle uses a crush washer and you reinstall the drain plug without one, you will likely develop a slow leak. Keep a pack of washers with your oil change supplies so they are always on hand.
Overtightening the filter or drain plug. Hand tight means hand tight. If you are reefing on the filter wrench or standing on the socket wrench, you are doing damage. Overtightened filters are extremely hard to remove later, and overtightened drain plugs can strip the oil pan threads.
Using the wrong oil viscosity. Your engine is designed for a specific viscosity grade. Using 10W-30 when the manual calls for 0W-20 can reduce fuel economy and increase engine wear, especially in cold starts. Always match the grade specified by the manufacturer.
Not checking for leaks after the change. A loose filter or drain plug will slowly drip oil onto your driveway and eventually cause the engine to run low. Always do a final leak check after starting the engine.
Used motor oil is toxic and should never be poured down a drain, into the soil, or thrown in the trash. The good news is that recycling it is easy and free.
Nearly every auto parts store in the United States accepts used motor oil for recycling at no charge. Stores like AutoZone, Advance Auto Parts, O'Reilly Auto Parts, and NAPA typically have a collection tank in the back. Just bring your sealed container of used oil to the counter, and they will take care of the rest.
Some municipalities also have household hazardous waste collection sites that accept used oil. Many communities even have curbside pickup programs for used oil on designated days.
Store your used oil in a sealed container with a tight-fitting lid. A clean plastic jug or your drain pan with its lid works well. Keep it in a cool, dry place until you can drop it off. This same disposal discipline applies to oil change schedules for standby generators and other small engines.
Choosing between synthetic and conventional oil comes down to your vehicle, your climate, and your budget. Here is what you need to know to make the right choice.
Synthetic oil is engineered in a lab to have uniform molecular structure. It resists breakdown at high temperatures, flows better in extreme cold, and lasts longer between changes. Most vehicles built in the last decade recommend or require synthetic oil. If your owner's manual specifies synthetic, use it.
Conventional oil is refined from crude petroleum. It is less expensive but breaks down faster under heat and does not flow as well in cold temperatures. Conventional oil is fine for older vehicles and those driven in mild conditions with conservative oil change intervals.
Synthetic blend oil combines the two. It offers some of the high-temperature protection of full synthetic at a lower price point. Blends are a reasonable middle ground for vehicles that do not specifically require full synthetic.
Regardless of which type you choose, stick to the viscosity grade and specification listed in your owner's manual. Mixing viscosity grades or ignoring manufacturer specifications can lead to engine problems over time.
The old rule of changing oil every 3,000 miles is outdated for most modern vehicles. Advances in oil chemistry and engine design have extended oil change intervals significantly.
For vehicles using synthetic oil, the typical oil change interval is between 7,500 and 10,000 miles, or once per year, whichever comes first. Some vehicles can go up to 15,000 miles between changes. Always follow the interval specified in your owner's manual, as it accounts for your specific engine design and oil type.
If you use conventional oil, the interval is usually 3,000 to 5,000 miles. Vehicles driven in severe conditions, such as frequent short trips, extreme temperatures, towing, or dusty environments, may need more frequent changes regardless of oil type.
Watch for warning signs between changes. If your oil life monitor (if equipped) shows low percentage, if the oil on the dipstick looks dark and gritty, or if you notice engine noise, it may be time for an early change. This attention to proper equipment maintenance extends engine life and prevents costly repairs.
Yes, you can change your engine oil by yourself. The process requires basic tools, about 30 to 45 minutes, and no special mechanical training. With a set of ramps or jack stands, a socket wrench, an oil filter wrench, and the correct oil and filter, any vehicle owner can complete this task at home.
Most modern vehicles using synthetic oil need an oil change every 7,500 to 10,000 miles or once per year. Vehicles using conventional oil typically need changes every 3,000 to 5,000 miles. Always check your owner's manual for the exact interval recommended for your specific make and model.
Yes, changing your own oil is worth it for most vehicle owners. A DIY oil change typically costs $25 to $45 in supplies compared to $60 to $100 at a shop. Over the life of a vehicle, this saves hundreds of dollars. It also lets you control the oil quality and filter brand used.
If you do not change your oil, it breaks down and loses its ability to lubricate engine components. This leads to increased friction, heat buildup, and sludge formation. Eventually, the engine can seize completely, resulting in thousands of dollars in repair or replacement costs.
Yes, you can change your oil without a jack by using vehicle ramps. Simply drive the front wheels onto a set of ramps, engage the parking brake, and chock the rear wheels. Ramps cost about $25 to $40 and are considered safer than working under a jack-supported vehicle.
Check your owner's manual for the recommended oil viscosity grade and oil capacity. The viscosity grade, such as 5W-30 or 0W-20, is also often printed on the oil fill cap under the hood. You can also ask any auto parts store to look up the correct oil and filter for your vehicle by make, model, and year.
Learning how to change your own engine oil step by step is one of the most practical skills any vehicle owner can develop. The process comes down to eight straightforward steps: prepare the car, lift it safely, drain the old oil, swap the filter, reinstall the drain plug, add fresh oil, and verify everything is sealed and at the correct level.
You do not need a mechanic's garage or years of experience. A set of ramps, a basic socket set, and about 30 minutes of your time are all it takes to do this job right. You will save money on every single change, know exactly what oil is in your engine, and build confidence that carries over into other DIY maintenance tasks.
The first time takes a little longer as you learn where everything is on your vehicle. By your second or third oil change, you will have the process down to under 30 minutes. Grab your supplies, clear a Saturday morning, and give it a try. Your wallet and your engine will thank you.
