Is e85 better than 93 octane?

E85 has an octane rating higher than that of regular gasoline’s typical rating of 87, or premium gasoline’s 91-93. This allows it to be used in higher-compression engines, which tend to produce more power per unit of displacement than their gasoline counterparts.

Is all 93 octane gas ethanol free?

No. All gasoline brands have both pure and ethanol-containing gasoline under the same brand names. For example, Shell V-Power ranges from 91 to 93 octane both with and without added ethanol. It just varies from station to station, and it’s up to the station owner whether or not to sell pure gas.

The E85 boosts the engine’s horsepower because of two factors: its amazing octane rating and cooling capacity. … Also, the fuel absorbs plenty of heat from the intake charge when transformed from gas to liquid inside the engine. A cooler intake charge lowers the rate of engine’s detonation and improves power output.

Is there ethanol in 93 octane?

Almost all gasoline now has some ethanol in it. In fact, in Madison, Wisconsin there is a Shell station that sells 93-octane V-Power with ethanol at most pumps, but which has a single pump, at a higher price, dispensing pure 91-octane gas. .

However, most drivers use the E10 or E15 blends, with 10-15% ethanol. That ethanol content only reduces gas mileage by around 5%.

Why is 98 octane better?

Fuels such as 95 or 98 RON (octane rating number) have a higher resistance to burn which indicates higher levels of energy available for the vehicle’s engine.

Can you run e85 on a 93 tune?

And long answer short, there is no benefit to mixing E85 and 91/93. Also, if your tune is for 93, adding more than 2 gallons to a full tank will require the ECU to adjust various parameters beyond what the tune is designed to do and therefore will be detrimental to performance.
