How to Change Your Engine Oil
Drain, filter, refill, and verify the level without damaging the engine or making a mess.
Changing engine oil is beginner-friendly, but it is not a casual job. You are opening the lubrication system, lifting the car, and trusting the refill amount to protect the engine.
Best practice: use the oil grade, capacity, filter, and drain-plug torque from your owner's manual, then verify the level after the engine runs.
What should you confirm before draining anything?
Confirm the oil spec, oil capacity, filter part number, drain plug location, and lift point before you touch the car. Do this while the engine is cool enough to work around.
Warm oil drains faster, but hot exhaust and oil can burn skin.
On a common sedan like the Toyota Camry, the routine is straightforward because parts are easy to find. The rule is the same for every gas or hybrid vehicle: the manual owns the spec, not a parts-store guess.
| Check | Why it matters | Bad outcome |
|---|---|---|
| Oil grade | Protects engine clearances and emissions systems | Noise, wear, or warning lights |
| Capacity | Prevents underfill or overfill | Low pressure or foaming |
| Filter | Must seal and flow correctly | Leaks or poor filtration |
| Washer | Helps the drain plug seal | Slow drip after the job |
| Lift point | Keeps the car stable | Injury or body damage |
How do you lift the car safely?
Use level ground, wheel chocks, a floor jack, and jack stands. Never work under a car supported only by a jack.
If the drain plug and filter are reachable without lifting, keep the car on the ground and save the risk.
The car should feel boringly stable before you slide under it. Shake it lightly at the body, confirm both stands are seated, and keep your phone within reach.
Safety is not a step to rush so the oil drains sooner.
What is the clean drain and filter order?
Position the drain pan before removing the plug because oil does not fall straight down at first. It can shoot sideways, then slow to a drip.
Remove the oil fill cap up top to help the flow.
After the oil drains, replace the filter. Wipe the filter mount, make sure the old gasket did not stick to the engine, lightly oil the new gasket, and hand-tighten the filter unless the filter design specifies a torque.
Clean-work cues
- Drain pan
- Place it ahead of the plug's first oil stream
- Old gasket
- Confirm it came off with the old filter
- New filter
- Oil the gasket before installation
- Drain plug
- Use a new washer when required
- Torque
- Use the manual's spec, not arm strength
How much oil should you add?
Add slightly less than the listed capacity first, wait a minute, and check the dipstick or electronic level system. Then top up slowly.
Overfilling can cause foaming and leaks, while underfilling can starve the engine.
Start the engine for 30 to 60 seconds, shut it off, wait a few minutes, and check again. Look under the car for drips at the drain plug and filter.
The final level matters more than pouring in a round number.
What should you do with the old oil?
Pour the old oil into a sealed container and take it to a recycling location, parts store, or service center that accepts used oil. Do not pour oil into a drain, soil, trash can, or storm sewer.
Record the date, mileage, oil grade, filter part number, and any leak you noticed. That record helps resale and prevents guessing next time.
If you are deciding whether to buy new or used, maintenance proof is one reason the new versus used guide stresses service records.
When should you not DIY an oil change?
Skip the DIY job if the car needs a special service procedure, the filter is hard to reach, the drain plug is damaged, the vehicle cannot be lifted safely, or you are unsure which fluid is engine oil. Some modern cars use underbody panels and cartridge filters that make mistakes easier.
If you find metal in the oil, a strong fuel smell, milky oil, or a stripped plug, stop and get help. Those are diagnostic clues, not normal maintenance details.
What else should you check while the car is in service mode?
Use the oil change as a broader inspection.
Check tire pressure, look for uneven tire wear, inspect visible leaks, confirm coolant level when the engine is cool, and look at the serpentine belt if your car has one.
You are already working slowly around the car, so use the time.
If the tires are low, follow the tire pressure guide before driving away.
If the battery sounds weak after the service, keep the jump-start steps handy but do not use them as a substitute for testing an old battery.
If you are maintaining a used car you just bought, the new versus used guide explains why early maintenance records matter.
Oil changes also support model research.
A clean service history helps a used Toyota Camry or Honda Civic hold value, while skipped oil service hurts even reliable cars. For shoppers comparing long-term sedans, the Civic vs Camry comparison gives the ownership frame.

Steps
- Confirm the oil spec and lift plan Read the owner's manual for oil grade, capacity, filter, drain-plug torque, and lift points before opening anything.
- Warm lightly, park safely, and support the car Run the engine briefly, park on level ground, set the brake, chock the wheels, and support the car with stands or ramps.
- Drain the old oil Place the pan ahead of the plug's first stream, remove the fill cap, loosen the drain plug, and let the oil slow to a drip.
- Replace the filter Remove the old filter, confirm the old gasket came off, oil the new gasket, and install the new filter to the specified tightness.
- Reinstall the drain plug Fit a new washer when required, thread the plug by hand first, then torque it to the manual's spec.
- Refill and verify Add slightly less than the listed capacity, check the level, run the engine briefly, check for leaks, wait, and top up slowly.
- Recycle and record Recycle the used oil and filter, then write down the date, mileage, oil grade, and filter part number.
