ETHANOL E85R 85%

SUNOCO ETHANOL E85R is blended to consisteltly contain 85% Ethanol. 

High alternative for race fuel, valid for all petrol engines (precise mapping is required). 
Ethanol conventiona E85 can vary from 68 to 79% ethanol, so very difficult to precise mapping. 
The non-ethanol portion of E85R is comprised of highly refined race fuel for stability and consistency. 
Special care must be taken with the components, since their high oxygen content is highly corrosive, so we recommend that the fuel system be compatible with Ethanol.

Note: Do not confuse E85 with E85R, the latter is mixed with race fuel.
