On-Vehicle Inspection

WARNING: This page is about a different car, the 2004 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.

CHECK ENGINE OIL LEVEL
1. After warming up the engine and then 5 minutes after the engine stops, oil level should be between the "L" and "F" marks on the oil level gage.
If low, check for leakage and add oil up to the "F" mark.

NOTE: Do not fill with engine oil above the "F" mark.
CHECK ENGINE OIL QUALITY
1. Check the oil for deterioration, entry of water, discoloring or thinning.
  If the quality is visibly poor, replace the oil.
  
  Oil grade:
  
  Use API grade SL "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, SAE 10W-30 may be used.
  
  However, it should be replaced with SAE 5W-30 at the next oil replacement.
