Hey guys,
Octane rating is just how much the fuel can be compressed before it explodes and make your car move forward... That means that (e85) has 85% ethanol and therefore the octane rating should be 100 or more. So e85 is better than regular
91 octane rating gas which only contains 10% ethanol or what?
What I learned in chemistry is that ethanol only has 2 carbons, therefore not producing enough energy. Additionally, ethanol is a alcohol family member
. Therefore, it will be corrosive for the engine.
So is it better to go unleaded gasoline with no ethanol?
