How to Change Oil in Your Car: A Simple 8-Step DIY Guide
To change oil in a car, warm the engine for a few minutes, lift the car safely on ramps or jack stands, drain the old oil from the drain plug, replace the oil filter, reinstall the plug with a new washer, refill with the oil grade and amount listed in your owner’s manual, then check the dipstick and look for leaks. Most cars take 4 to 6 quarts and the whole job takes about 30 to 60 minutes.
Changing your car’s oil might sound like a job for the pros, but learning how to change oil in a car is one of the most useful skills you can pick up. It saves money, and it puts you in control of your engine’s health. I still remember my first time: I was nervous, clumsy, and spilled a bit, but I felt like a real mechanic afterward.
In this guide, we’ll walk through everything step by step, from choosing the right oil to the final leak check. Whether you’re working in a garage or a driveway, you’ll know exactly what to do by the end.
Why Oil Changes Matter More Than You Think
Engine oil keeps moving metal parts from grinding against each other, carries heat away, and traps dirt. Over time it breaks down, gets thick with sludge, and stops protecting your engine the way it should.
If you skip oil changes, here’s what can go wrong:
- Faster wear on bearings, the timing chain, and other internal parts
- Engine overheating and sludge buildup
- Lower fuel economy
- A very expensive engine repair, or a dead engine
A friend of mine skipped three oil changes because “life got busy.” A year later he was $3,000 deep in engine repairs. A small habit could have saved him.
What You’ll Need Before You Begin
Before you buy anything, open your owner’s manual. It lists three things you need: the oil grade (for example 0W-20 or 5W-30), the oil capacity with a filter change, and the drain plug torque. Using the wrong oil can cause more harm than good.
Which Oil Should You Use?
| Oil type | Best for | Typical change interval |
|---|---|---|
| Conventional | Older, simple engines with light use | About 3,000 to 5,000 miles |
| Synthetic blend | Everyday driving, some towing | About 5,000 to 7,500 miles |
| Full synthetic | Most modern and turbocharged engines | About 7,500 to 10,000 miles |
| High mileage | Engines past 75,000 miles with small leaks | Follow your manual |
Always match the viscosity in your manual, and look for the API “donut” symbol on the bottle. The newest gasoline engine category is API SQ, which replaced API SP in 2025, and it is backward compatible with older categories. Some carmakers also require their own approval, such as GM dexos1, so check for it on the label. Not sure whether you need synthetic?

How to Change Oil in a Car: Step by Step
Run the engine for 2 to 3 minutes so the oil flows out easily, then shut it off and wait until the oil pan is warm, not hot.
Park on flat ground, set the parking brake, chock the rear wheels, and raise the front on ramps or jack stands. Never work under a car held up only by a jack.
Remove the oil filler cap, place the drain pan under the drain plug, loosen the plug counterclockwise, and let the oil drain for 10 to 15 minutes.
Move the pan under the filter, loosen it with a filter wrench, and make sure the old rubber gasket came off with it.
Wipe a film of new oil on the new filter’s gasket and hand-tighten it. Reinstall the drain plug with a new washer and torque it to spec.
Lower the car. Using a funnel, pour in about half a quart less than the listed capacity, wait a minute, then check the dipstick and top up.
Start the engine for 30 to 60 seconds, shut it off, wait 5 minutes, recheck the dipstick, and look under the car for drips at the plug and filter.
Pour the used oil into a sealed container, take it and the old filter to a collection point, and reset the oil life monitor.
Step 1: Warm the Engine, Then Let It Cool a Little
Warm oil flows faster and carries more dirt out with it, but hot oil can burn you badly. Run the engine for a couple of minutes, switch it off, and wait until you can comfortably touch the oil pan. If you just came back from a long drive, give it 20 to 30 minutes.
Wear old clothes, gloves, and safety glasses. Oil in the eye is no fun.
Step 2: Lift and Secure the Car
Find a flat, solid surface such as a garage floor or driveway. Put the car in park (or in gear for a manual), set the parking brake, and chock the wheels that stay on the ground.
Drive-up ramps are the easiest option for beginners. If you use a jack, lift at the jack point in your manual and then lower the car onto jack stands before you go underneath. Rock the car gently to make sure it is stable.
Never get under a car that is supported only by a jack. Jacks can slip or fail without warning. Always use jack stands or ramps rated for your vehicle’s weight.
Step 3: Drain the Old Oil
Open the hood and remove the oil filler cap so air can get in and the oil drains faster. Slide the drain pan under the drain plug, which is the large bolt at the lowest point of the oil pan. Loosen it counterclockwise with your wrench, then unscrew the last few turns by hand while pushing inward, and pull it away quickly.
The oil comes out at an angle at first, so position the pan a little ahead of the plug. Let it drain for 10 to 15 minutes until it slows to an occasional drip. Wipe the plug clean and keep it somewhere you won’t lose it.
Take a look at the old oil. Dark is normal. Milky oil or metal flakes are not, and they are worth showing to a mechanic.
Step 4: Remove the Old Oil Filter
Move the pan under the oil filter, since it holds about half a quart of oil. Loosen the filter with an oil filter wrench, then spin it off by hand. Some cars use a cartridge filter inside a plastic housing on top of the engine instead. If yours does, follow the manual and replace the housing O-ring that comes with the new filter.
Check that the old rubber gasket came off with the filter. If it stuck to the engine and you install the new filter on top of it, the double gasket will leak badly as soon as you start the car. Wipe the mounting surface clean.
Step 5: Install the New Oil Filter and Drain Plug
Dip a finger in new oil and wipe a thin film on the new filter’s rubber gasket. This helps it seal and makes it easier to remove next time. Screw it on by hand until the gasket touches, then tighten about three quarters of a turn more, or as printed on the filter. No wrench needed.
Put a new crush washer on the drain plug, thread it in by hand, and tighten it to the torque in your manual. Many passenger cars fall somewhere around 20 to 30 lb-ft, but yours may differ. Overtightening is the classic way to strip an oil pan, which turns a $40 job into a $400 one.
Step 6: Add the New Oil
Lower the car so it sits level. Place a funnel in the filler opening and slowly pour in the new oil. Start with about half a quart less than the capacity in your manual. Most cars take 4 to 6 quarts, but some engines take much more.
Wait a minute for the oil to settle, then check the dipstick and add a little at a time until the level is near the full mark. Replace the filler cap.
Step 7: Run the Engine and Check for Leaks
Start the engine and let it idle for 30 to 60 seconds. The oil pressure light should go out within a few seconds. Shut the engine off, wait about 5 minutes, and check the dipstick again. Top up if needed.
Look under the car at the drain plug and filter. A dry plug and a dry filter mean you nailed it. If you see a drip, tighten the part slightly and check again.
Step 8: Recycle the Old Oil and Reset the Reminder
Never dump used oil in the trash, down a drain, or on the ground. According to the U.S. EPA, the oil from one oil change can contaminate a million gallons of fresh water. Pour it into the empty oil jugs, let the old filter drain into the pan, and take both to an auto parts store or recycling center. Many accept them for free.
Finally, reset the oil life monitor or maintenance light. The steps vary by car. You can usually find them in the manual, or in our guides such as resetting oil life on a Ford F-150. Write down the date and mileage, too.
Common Oil Change Mistakes to Avoid
- Use the exact grade in your manual
- Replace the filter every time
- Use a new drain plug washer
- Fill slowly and check the dipstick
- Work under a car on a jack alone
- Overtighten the plug or filter
- Leave the old gasket stuck on
- Overfill the engine
Overfilling is more common than people think. Too much oil can get whipped into foam by the crankshaft, which reduces lubrication and can push oil past seals. If you see oil spots afterward, our guide on where oil leaks come from will help you find the source.
Signs Your Oil Needs Changing
- Oil change or maintenance light on the dashboard
- Dark, gritty oil on the dipstick, or a level below the minimum mark
- Louder engine noise, such as ticking or knocking
- Burning oil smell inside the car
- You are past the mileage or time listed in your manual
A red oil pressure light while driving is not a reminder. It means low oil pressure. Pull over safely and switch off the engine as soon as you can.
How Often Should You Change Your Oil?
The old rule of every 3,000 miles is outdated for most modern cars. Many cars now go 5,000 to 7,500 miles, and some go 10,000 miles on full synthetic. Your owner’s manual and the car’s oil life monitor are the best guide.
Change it sooner if you drive in “severe” conditions: lots of short trips, stop-and-go traffic, towing, dusty roads, or extreme heat or cold. Even if you drive very little, most makers say to change the oil at least once a year.
DIY Oil Change vs Going to a Shop
| DIY at home | Quick-lube or dealer | |
|---|---|---|
| Typical cost | $30 to $70 for oil and filter | About $50 to $130, more for synthetic |
| Time | 30 to 60 minutes | 30 to 60 minutes plus travel and waiting |
| Best for | Learning your car and saving money | No tools, no space, or a car that is hard to reach |
For a model-specific example, see how much an oil change costs for a Toyota Camry. And while you are building your DIY skills, learn how to change a flat tire too. It is the other job every driver should know.
- Buy the filter and the oil before you start, and confirm the filter part number for your exact engine.
- Put a large piece of cardboard under the drain pan. It catches the splashes.
- Set a phone reminder for your next change based on miles or months.
- Keep a small log of the date, mileage, oil, and filter used. It helps resale value.
Changing your own oil is simple once you have done it once: lift the car safely, drain, swap the filter, refill with the right oil, and check for leaks. Follow your manual for the oil grade, capacity, and torque, and you will save money while keeping your engine healthy for many miles.
Oil Change FAQs
About 30 to 60 minutes for a first-timer, including draining time. With practice, most people can do it in 20 to 30 minutes.
Most cars take 4 to 6 quarts with a filter change, but it varies by engine. Your owner’s manual lists the exact capacity. Fill about half a quart short, then top up using the dipstick.
Warm, not hot. Run the engine for 2 to 3 minutes so the oil flows well, then let it cool until the oil pan is safe to touch.
Yes, it is best practice. A new filter is cheap, and an old one still holds dirty oil that would mix with your fresh oil.
Sometimes. Some cars with a top-mounted filter can use an oil extractor pump through the dipstick tube. Most cars still need to be raised safely on ramps or jack stands to reach the drain plug.
A little over the full mark is usually not a problem, but a lot can cause foaming, oil leaks, and smoke. Drain the extra out through the drain plug or with an extractor.
Yes. Synthetic oil is safe in nearly all engines as long as it matches the viscosity and specification in your manual. You can also switch back later.
Most auto parts stores, quick-lube shops, and local recycling centers accept used oil and filters, often for free. Bring it in a sealed container.
- Check the manual for oil grade, capacity, and drain plug torque.
- Lift the car with ramps or jack stands, never a jack alone.
- Drain the oil, replace the filter, and use a new plug washer.
- Fill half a quart short, then top up using the dipstick.
- Check for leaks, recycle the old oil, and reset the reminder.
