Maintain the oil level on the dipstick between the FULL RANGE mark and the ADD OIL mark. Add oil if the oil level is too low.Note: Operating your engine with the oil level above the FULL mark in the FULL Range could cause the crankshaft to dip into the oil. This could result in excessively high operating temperatures. The high operating temperatures could result in reduced lubricating characteristics of the oil. This could cause damage to the bearings and loss of engine power.Add The Engine Oil
