Step 1 of 7
Warm Up the Engine
Run the engine for 2-3 minutes. Warm oil flows faster and carries more contaminants. Park on a level surface and engage the parking brake.
Tip
Don't run the engine too long — hot oil can cause burns.
Step 2 of 7
Locate and Remove Drain Plug
Slide under the vehicle and locate the oil drain plug on the bottom of the oil pan. Place your drain pan underneath. Use a socket wrench to remove the plug. Oil will flow out quickly.
Warning
Oil may be hot. Wear gloves and eye protection.
Step 3 of 7
Remove Old Oil Filter
Locate the oil filter (consult manual if needed). Use an oil filter wrench to loosen it. Unscrew by hand and let it drain into the pan. Compare the old and new filter to ensure they match.
Step 4 of 7
Install New Oil Filter
Apply a thin film of new oil to the new filter's gasket. Thread it on by hand until the gasket contacts, then tighten ¾ turn more. Do not overtighten.
Common Mistake
Overtightening the oil filter — hand-tight plus ¾ turn is all you need.
Step 5 of 7
Replace Drain Plug
Once oil has fully drained, reinstall the drain plug with a new washer if needed. Tighten to manufacturer's torque specification — usually 25-30 ft-lbs.
Step 6 of 7
Add New Oil
Remove the oil fill cap on top of the engine. Insert a funnel and pour in the correct amount and type of oil. Check your manual — most engines take 4-6 quarts.
Tip
Start with about 80% of the specified amount, check the dipstick, then add as needed.
Step 7 of 7
Check Level and Dispose
Start the engine and let it run for a minute. Shut off and wait 5 minutes. Check the dipstick — oil should be between the two marks. Properly dispose of used oil at an auto parts store or recycling center.
Warning
Never pour used oil down a drain or in the trash. It's toxic and illegal.
