If you're committed to using E85 type fuels, C85 is by far your best choice. Conventional E85 fuels are notoriously inconsistent. By contrast, C85 is blended with a consistent proportion of ethanol and every other component in every drum.

C85 makes up to 4% more power and torque than conventional E85. With higher quality pure components, C85 is superior to E85 in terms of the cooling effect, resistance to detonation and even includes corrosion inhibitors to fight the issues presented by ethanol. C85 works well in drag racing, oval track, off-road and virtually any other automotive application, in particular, forced induction applications due to its lower vapour pressure.

DO NOT USE WITH INJECTORS THAT ARE NOT COMPATIBLE WITH MTBE.
