pump gas

So I was just wondering if our cars do better with 93octane with the 10%ethanol or just 93octane without the 10%ethanol.

I was wondering this because I know some cars run better with it and some run better without it.

I would run straight 93. Its hard to maintain 10% perfect mixed.

Our cars run super rich from the factory (under boost) so adding in the 10% ethanol helps just a tiny bit.

all gasoline since the 80's has 10% ethanol in it.

back in the gas crunch of the 70's and 80's it became federally mandated. there is now a push to go for 15% of ethanol in the mixture, but there are a lot of idiots who don't understand that this will help us instead of hurt us.

93 will burn longer in the combustion chamber than 87, and e85 will burn longer than 93, and 116 burns longer than all of them.

the longer burning in the combustion chamber means you can make more power, increase more timing, and up the boost and have awesome afr's and maps.

He is referring to the fact that most gas in the US comes with 10% ethanol straight from the pump.
