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 low level and full level marks on the level gage.

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

1. Check the oil for deterioration, entry of water, discoloring 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. 

1. Disconnect the oil pressure switch connector.
2. Using a deep socket wrench 24 mm, remove the oil pressure switch.

4. Warm up the engine.
5. Inspect the oil pressure.
