Engine Oil: Testing and Inspection

Inspection

Engine Oil
1. Check engine oil quality.
Check the oil for deterioration, entry of water, discoloring or thinning.
If the quality is visibly poor, replace oil.
2. Check the engine oil level.
After warning up the engine, make the engine stand still for five minutes or more. The oil level should be between the 'L' and 'F' marks on the dipstick, then.
If low, check for leakage and add oil up to the "F" mark.

NOTE:
Do not fill with engine oil above the "F" mark.
