VP Products




VP’s best fuel yet for 4-stroke applications that can tolerate lower octane values, makes more power for powersport applications than any fuel on the market. Dyno tests proved up to 5% more power than VP’s MR9 and up to 6% more power than VP’s MRX01! Although currently not legal in AMA Pro Racing, MR12 passes fuel rules for AMA Pro/Am, CCS, WERA, AFM, NMA, WORCS, SCORE and Best in the Desert as well as club level racing and more.

Tech Tip:

When using MR12, to keep your fuel cool and prevent vapor lock on hot days, e.g. 90 ° or higher, we recommend:

  • Always go out with a full tank – the more fuel you have the cooler the fuel will stay
  • Insulate the bottom of your fuel tank:
  • line the underside of the tank with heat reflective tape and/or
  • install a CV4 Fuel Kool Gas Tank Barrier
  • It will also help to keep your fuel container wrapped in a RACEPRO “Cool Fuel” Ice Jacket prior to dispensing in your fuel tank.
