Thor Oil has proven its durability under racing conditions encountered in Gold Cup, Pavement, and Dirt National and Divisional Series, and of course local kart racing. While providing the maximum engine protection and lubrication, Thor Oil does not produce the carbon build-up on the engine head and piston as encountered in other oils. Thor Oil is a synthetic oil manufactured from pure feedstock's and oil additives. Thor Oil will not mix with petroleum based oils.

Thor Oil comes in two viscosity options, LIGHT and HEAVY. 

THOR OIL LIGHT is recommended for all restricted classes and  all stock classes (light, medium, heavy). 

THOR OIL HEAVY is recommended for controlled stock, superstock, and limited modified classes.

THOR CLONE oil was specifically designed for the clone engines, however Light will also work fine.
