Tools You'll Need

Step-by-Step

1. Warm the engine for 2-3 minutes so the oil drains cleanly, then shut it off.
2. Raise the vehicle safely on ramps or jack stands. Never work under a car held by a jack alone.
3. Position the drain pan and remove the drain plug. Let it drain fully (5-10 min).
4. Remove the oil filter (turn counter-clockwise). Have the pan ready — it holds oil.
5. Lightly oil the new filter's gasket, then hand-tighten 3/4 turn past contact.
6. Reinstall the drain plug with a fresh washer and torque to 25 ft-lb.
7. Lower the vehicle and add 4.9 quarts of 0W-20 full synthetic through the filler.
8. Run the engine 30 seconds, check for leaks, then re-check level on the dipstick.
