On-Vehicle Inspection

1. Warm up the engine, then stop the engine and wait for 5 minutes.
2. Check that the engine oil level is between the "L" and "F" marks on the level gage.

If low, check for leakage and add oil up to the "F" mark.

1. Check the oil for deterioration, water intrusion, discoloration or thinning.

   If the quality is visibly poor, replace the oil.

   1. Oil grade: 
   2. Use API grade SL "Energy-Conserving", or ILSAC multigrade engine oil. 
   3. SAE 5W-30 is the best choice for good fuel economy, and good starting in cold weather. 
   4. If SAE 5W-30 is not available, SAE 10W-30 may be used. 
   5. However, it should be replaced with SAE 5W-30 at the next oil replacement.
