On-Vehicle Inspection

1. Warm up the engine, stop it and wait 5 minutes. The oil level should be between the dipstick's low level mark and full level mark.

   If low, check for leakage and add oil up to the full level mark.

   NOTE: Do not fill above the full level mark.

1. Check the oil for deterioration, water contamination, discoloring or thinning.

   If the quality is visibly poor, replace the oil.

   Oil grade: 

   API grade SL, Energy-Conserving or ILSAC, multi-grade engine oil is recommended. SAE 5W-30 is the best choice for good fuel economy and good starting in cold weather. 

   If SAE 5W-30 in not available, SAE 10W-30 may be used.

   However, it should be replaced with SAE 5W-30 at the next oil change.
