Ethanol Free Gas

Found a gas station that has 93 ethanol free gas. Was thinking about trying it has I hear good things about. Just was not sure running a turbo SS with cam etc it this would be bad for the car and or tune.

Anyone tried this?

Don't know what or how you are tuned now. If you were dialed in on E10 93, it will run 2-3% richer on E0 93 WOT. The LTFT's will compensate at cruise, ect. pulling a few % but the trims will not pull fuel WOT, they only add if needed from the LTFT's.

Ethanol Free gas makes more power and will not hurt anything.

but I suspect it stil has Some Ethanol in it for Federal Emission Reasons.

Thanks for the answer Ted!! You always bring good info to the table. That's why you always get emails from me on stuff. :-)

Check out the website www.pure-gas.org. It lists station that claim to have a pumps with no ethanol.

+1, there is no such thing as Ethenol free in the US. If they are telling you that. they are lying to you. In fact all gas coes from one of a very few refineries. The only differences are the additives that they put in for each brand. Top Fuel has cleaning agents in the gas to keep yor engines runnig cleaner by allowing the fuel to burn fuller on each cycle. Cheap fuel is actuall more 'pure' than top fuel, but you dont want to put that junk your your car. You want those cleaning agents, especially in an SS.

It's acutely more expensive.

There is a station near where I work that offers both E10 and pure gas in regular grade. I've used both in by Alero depending on the relative price of each. The pure gas consistently returns 2.5 mpg better than the E10, so clearly there is actually a big difference between them.

Also, it is a myth that premium keeps the car cleaner than regular. It may have been true in the 50s and 60s, but it hasn't been for decades. The only possible reason to run premium over regular is if your engine is high enough compression to need it.

There are only 149 refineries in the US to date. They all put ethenol into the the fuel except for perhaps Alaska. If it is less than 10% they stations are not required to notify you of the fact that is exists on the fuel. Normally it is about 5.9% but can be lower. It will almost always be greater than 2%.

In fact, most states mandate that gas have ethenol and the refineries do have a financial in include it as it is government subsidized so they can sell more petroleum at a higher margin with it's inlcusion. So, my comment may not be completely accurate, stations are probably not lying, they are just mis-informed, as is the web site pointing to ethenol free fuel. In fact, most the stations listed on that web site are NOT top fuel. Shamrock is NOT top fuel.

E10 is 10%, regular is somewhere between 2-5 % but up to 10%. E10 can actually be 10-15%.

Don't think they had Premium in the 50's/60's, Everything was leaded gas till around 74.
