SA 9127E Gage Bar Set

Important: As shown in this chart, SAE 5W-30 is best for your vehicle. However, you can use SAE 10W-30 if its going to be -7°C (+20°F) or above. These numbers on an oil container show its viscosity, or thickness. Do not use engine oil with a viscosity rating such as 10W-40, SAE 20W-50 and W30 as it does not meet Saturn recommended requirements.

Important: Engine additives should not be added to your engine oil.

1. INSERT GRAPHIC 61096AD
