Is there an advantage to buying the gas that has zero ethanol in it? I've seen this on a 93 octane pump before, where the other two had the standard "may contain up to 10% ethanol".

I know the ethanol can harm smaller 2 stroke motors, but is there a noticeable difference when you use this in our cars?

 

I would think not considering how many people on here are using E85, but someone else will in here to chime in. out of curiosity where do you live?

 

Ethanol will make less power per unit than gasoline. The advance of ethanol or primarily E85 is that the increase and octane which allows for a better advance timing. Which in a tune can lead to increasing more power. Without a tune, pure gasoline will make more power. And be dirtier bc of carbon build up

 

Ethanol has less energy than gasoline, so 93 octane gasoline w/o ethanol will provide more power and better fuel efficiency (yes, both). While ethanol provides increased octane when blended with gasoline, a 93 octane ethanol-blended gasoline is just that...93 octane. Refiners can make a lower sub-octane base gasoline blendstock (at lower cost) that uses ethanol to achieve the desired octane.

 

I live in Atlanta. I haven't actually seen it here. Just saw it in Charleston SC last week, but heard on the radio this morning that it is becoming more common in this area.

 

There is a place in Florence, SC called Old Delmae Grocery that has 93 Octane no Ethanol Premium gasoline. That's where I get gas for my lawnmower and other small engines.

 

I use Tiger 93 non-ethanol in my car. There's an old service station down the road that carries it. It's a bit more expensive than standard 93 with ethanol though.

 

I get 3mpg more per tank and noticeably more power with 100% gasoline. Ethanol is useless. Using up food to make fuel...great thinking America.
