The engine will be equipped with either dipstick.
(1) Traditional dipstick. (2) Full range dipstick.
Verify that the markings on the engine oil level gauge are correct. Verify the markings at the first oil change.Use the following procedure in order to verify that "ADD" mark is correct. Use the following procedure in order to establish actual "FULL" mark on the engine oil level gauge.
The engine must be on a level surface to perform this maintenance procedure.
Operate the engine until normal operating temperature is achieved. Stop the engine. Remove the drain plugs from the engine crankcase. Allow the engine oil to drain.
Do not fill the oil filters with oil before installing them.This oil would not be filtered and could be contaminated.Contaminated oil will cause accelerated wear to the engine.
Remove the used engine oil filter(s). Install the new engine oil filter(s). Install the drain plug for the engine crankcase. Tighten the drain plug for the engine crankcase to 70 14 N m (50 10 lb ft). Note: The engine may be equipped with auxiliary engine oil filters. The oil filters may require a different volume than the standard amount. Refer to the OEM specifications.
Pour 26.5 L (28 qt) of engine oil into the engine crankcase. DO NOT pour oil into the oil filler that is located on top of the engine. Pour oil into one of the oil fill locations on the side of the engine. Allow enough time for the engine oil to drain into the engine crankcase. Check the engine oil level. Wait for a few minutes. Check the engine oil level again. Proceed after the engine oil level stops changing.
The oil level should be at the "ADD" mark. If the oil is not at the "ADD" mark, grind off the existing "ADD" mark. Mark the new level as "ADD" using an engraving pen.
Pour 5.7 L (6 qt) of engine oil into the engine crankcase. Allow enough time for the engine oil to drain into the engine crankcase. Allow a minimum of five minutes.
Install the oil level gauge. Remove the gauge and note the oil level on the gauge. This is the new "FULL" mark on the dipstick. If the oil is not at the "FULL" mark, grind off the existing "FULL" mark. Mark the new level as "FULL" using an engraving pen.
Pour 5.7 L (6 qt) of engine oil into the engine crankcase for the filter or filters and margin.
Start the engine. Ensure that the lubrication system is filled. Inspect the lubrication system for leaks.
Stop the engine and allow enough time for the engine oil to drain into the engine crankcase. Allow a minimum of five minutes.
Check the engine oil level on the engine oil level gauge. If the engine oil level is not at the calibrated "FULL" mark, fill the sump to the calibrated "FULL" mark. Record the amount of oil that is added. This additional engine oil is the system capacity plus the 38 L (40 qt) in the sump. This additional engine oil is the amount of engine oil that is required when the engine oil is changed. Record the engine oil capacity for the system for future changes of the engine oil.
