engine, first ensure the engine is at full operating tem-
perature, then wait at least 15 minutes after engine
shutdown to check the oil.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Always
maintain the oil level within the SAFE zone on the
dipstick. Adding one quart of oil when the reading is at
the bottom of the SAFE zone will result in a reading at the
top of the safe zone on these engines.
CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could dam-
age your engine.
Never operate the engine with oil level below the “ADD”
mark or above the upper “SAFE” mark.
