OIL VISCOSITY INDEX CHART


 

 

Listed below is an oil viscosity index chart that shows the viscosities in relation temperature.

 

Never substitute SAE Crankcase oil for SAE Gear oil. Gear oil has EP additives that protect the gears from scuffing.

Always choose an oil that has the proper GL ratings. Check your owners manual for the correct GL rating.

Pay attention to all your drivetrain temperatures.  It wise to record temps after each track session.

The higher drivetrain temperatures that are seen in road racing applications generally require higher viscosity oils.

Vehicles that are being road raced require race car maintenance and all drivetrain oils should be inspected after each race and preferably changed.
