This PI was superseded to update Recommendation/Instructions. Please discard PIP5231.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern
The Engine oil dipstick indicates an overfill when performing a PDI or after an oil and filter change.
Recommendation/Instructions
Typically you will find the dipstick indicates an overfill of 1/2qt of Engine oil.
There is no need to drain the oil at this time, as this concern will not damage the engine nor affect operation.
When it is time for the oil change, fill with the recommended amount of engine oil as specified in SI
SI has been updated with the engine oil (with filter) fill specification of 8 quarts or 7.57 Liters for 5.3L, 6.2L RPO's L83, L86 engines in the models lists above.
Note: The correct “full” mark is the upper dimple and the “add” mark is the lowest bottom dimple on the Engine oil dipstick
