VP Racing Fuels C85 is the most powerful blend on the market. Countless dyno results have proven to show, C85 makes 5% more than pump gas and the V8 supercar blend.

Unlike pump E85, X85 is consistent from batch to batch and is always blended with 85% ethanol. Another added benefit, X85 is formulated with the highest quality 15% racing fuel gasoline.

Unlike X85, C85 requires you to retune your engine to suit the fuel. This fuel is not a straight tip in. C85 requires a fuel increase. You also have to make sure your injectors are compatible with MTBE.

Like all alcohol fuels, E85 is extremely corrosive. Over time E85 will cause issues with your fuel system and engine internals. If you're running E85, it's recommended you run our M2 Upper Cylinder Lubricant
