| 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 HEAVY is recommended for controlled stock, superstock, and limited modified classes. $19.95~GALLON |
