VP Racing C85 Race Fuel

VP C85 is a race-grade ethanol fuel formulated for competition engines running E85-compatible fuel systems. Unlike pump E85, which varies from 51% to 83% ethanol depending on season and region, C85 is blended to a fixed specification every batch. That consistency is what makes it tunable and repeatable for competition use.

C85 produces up to 4% more power and torque than conventional E85, with a 106 Research Octane Number and 31.97% oxygen content. It is unleaded and compatible with E85 fuel systems. Do not use with fuel injectors that are not compatible with MTBE.

Note: Due to state regulations, C85 is not currently available in CO, CT, MA, NH, or NY.

Key specifications:

Available in 5-gallon pails only. Hazmat shipping surcharge applies.
