On-Vehicle Inspection

WARNING: This page is about a different car, the 2007 Toyota Tacoma. However, it is still accessible from the selected car via links, so may be relevant.

CHECK ENGINE OIL LEVEL
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 gauge.
  If low, check for leakage and top oil up to the full level mark.
  
  NOTE: Do not fill with engine oil to above the full level mark.
CHECK ENGINE OIL QUALITY
1. Check the oil for deterioration, water intrusion, discoloration or thinning.
  If the quality is visibly poor, replace the oil.
  
  Oil grade: Use API grade SM "Energy-Conserving" or ILSAC multigrade engine oil.
  
  SAE 5W-30 is the best choice for good fuel economy and good starting in cold weather. If SAE 5W-30 is not available, use SAE 10W-30.
  
  However, it should be replaced with SAE 5W-30 at the next oil replacement.
