If you’re committed to using E85 type fuels, C85 is by far your best choice. 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 products. C85 works well in drag racing, circle track, off road and virtually any other automotive application. Note: Do not use with fuel injectors that are not compatible with MTBE.
