Why does e85 make more power?

The E85 boosts the engine’s horsepower because of two factors: its amazing octane rating and cooling capacity. The octane rating indicates a fuel’s power to withstand denotation or knock. … E85’s octane rating is 105, but it provides even better performance because of the cooling capacity.

Does flex fuel get better gas mileage?

Flex fuel gas mileage tends to be somewhat less than standard gasoline mileage. … However, since ethanol has at best, an 85 percent energy density, when compared to gasoline, you can see that ethanol does not get better gas mileage. Raising the octane level may increase mileage a bit, but not enough to notice.

Why is the mileage a vehicle gets less when burning e85?

Why is the mileage a vehicle gets less when burning E85 than 100% gasoline? Ethanol has a lower heat combustion.
