Engine Oil

Inspection

1. Check engine oil with the engine off and the car

parked on level ground.

2. Make certain that the oil level indicated on the

dipstick is between the upper and lower marks.

3. If the level has dropped close to the lower mark,

add oil until it reaches the upper mark.

CAUTION: Insert the dipstick carefully to avoid

bending it.ProCarManuals.com

Replacement

CAUTION: Remove the drain plug carefully while the en-

gine is hot, the hot oil may cause scalding.

1. Warm up the engine.

2. Drain the engine oil.

3. Reinstall the drain plug with a new washer, and refill

with the recommended oil.

NOTE: Under normal conditions, the oil filter should be

replaced at every other oil change. Under severe condi-

tions, the oil filter should be replaced at each oil change.ProCarManuals.com
