To ensure proper engine lubrication, the engine oil must be maintained at the correct level. Check the oil level at regular intervals, such as every fuel stop. The best time to check the engine oil level is about five minutes after a fully warmed up engine is shut off.
Checking the oil while the vehicle is on level ground will improve the accuracy of the oil level readings.
There are four possible dipstick types:
Crosshatched zone.
Crosshatched zone marked SAFE.
Crosshatched zone marked with MIN at the low end of the range and MAX at the high end of the range.
Crosshatched zone marked with dimples at the MIN and the MAX ends of the range.
Always maintain the oil level within the crosshatch markings on the dipstick.
Adding 1 qt (1 L) of oil when the reading is at the low end of the dipstick range will raise the oil level to the high end of the range marking.
Overfilling or underfilling the crankcase will cause oil aeration or loss of oil pressure. This could damage your engine.
