On-vehicle Inspection ON-VEHICLE INSPECTION PROCEDURE 1. CHECK ENGINE OIL LEVEL (a) Warm up and stop the engine, then wait for 5 minutes. (b) Check that the engine oil level is between the low level and full level marks on the engine oil level dipstick. If the level is low, check for engine oil leaks and add engine oil to the full level mark. NOTICE: Do not fill to above the full level mark. HINT: A certain amount of engine oil will be consumed while driving. In the following situations, engine oil consumption may increase, and engine oil may need to be refilled in between oil maintenance intervals.
When judging the amount of oil consumption, keep in mind that the oil may have become diluted, making it difficult to judge the true level accurately. 2. CHECK ENGINE OIL QUALITY (a) Check the engine oil for deterioration, water intrusion, discoloration or thinning. If the quality is visibly poor, replace the engine oil and oil filter element. 3.
