Clear gas Ethonal free? Any good ?

So they just opened a gas station close by my house, i normally put shell gas 91 premium v power. And saw that other gas station had clear gas ethanol free. I read that it you get better gas mileage? And better performance? So my question is, should i go with the ethanol free ? Or just stick with shell?

Where I live Shell V-power does not have any ethanol. Ethanol on a turbo car is not a bad thing for power at all .... storage is another matter. If you put it away for the winter put ethanolfree in it.

Normally aspirated and old I would go for ethanol free but not on a fairly modern turbo car .....

Whats the octane rating on the clear gas? Sounds like a good idea to just run the 100% gas especially for mileage reasons. Certainly should gain some mileage performance.

Just curious about any power loss due to lower octane? That clear gas is also spendy!

But, the other caveat would be that your tune should reflect your gas choice, so you would likely be tied to the clear gas going fwd

Just my .02 thoughts

100% gasoline will knock more than gasoline with 10 or 15% ethanol in it.

just fyi.

Usually ethanol gas is sold as use for recreational use in sleds, atvs, outboard motors, etc. or really anything that isn't supposed to be run with ethanol. It's usually labeled as RC90, it's 90 octane ethanol free gas and it's anywhere between $5-7/gal. You'd get better mpg but it'd barely be noticeable and you definitely wouldn't be saving any money.
