Why is ethanol free gas more expensive?

Each year, the laws require that the number of gallons of blended gasoline increase. As a result, pipelines are sending refineries sub-octane gas that needs ethanol or premium gasoline blended with it before it goes on sale. As refineries start to cut this amount of pure gas, it is becoming scarcer and more expensive.

Whats better e85 or 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.

Does ethanol reduce gas mileage?

MPG. Due to ethanol’s lower energy content, FFVs operating on E85 get roughly 15% to 27% fewer miles per gallon than when operating on regular gasoline, depending on the ethanol content. Regular gasoline typically contains about 10% ethanol.

Why is e10 cheaper than unleaded?

At the pump, E10 is generally the cheapest petrol per litre. Because the energy provided by the ethanol is less than the energy provided by pure petroleum, E10 has around 3% less energy than the equivalent amount of RON 91 petrol.

Is e10 better than unleaded 91?

E10 petrol is actually a slighter higher octane (94) than regular 91 in a lot of cases, and that can mean your engine performs better. However, ethanol lowers the energy level of the blend by 30%, which means you may experience a slight loss in fuel economy.
