10% ethinol in oklahoma
Here in Oklahoma as of July all of the gas station pumps are labeled "may contain up to 10% ethinol". Is this something that is going on nationwide yet? I have been told by some friends that work in refineries that they have been mixing ethinol for some time. There is only one station here in the small town that I live in that advertises "pure" gasoline. It's a Diamond Shamrock but he doesn't sell premium. All I can say is that I noticed that the Vette seems to be getting slightly worse gas mileage. I'm just hoping this stuff isn't damaging the fuel system.

You are good to go
It's pretty much nation wide,,I was actually kind of surprised to hear there was somewhere that didn't have it!! Illinoi an many others hafe had it for years with NO TROUBLE !! No real problems even in my 69 big block(I did have hardened valve seats put in the heads for unleaded gas). As you noted you get a small MPG drop and that's it. Kind of ironic they put 10% in to stretch the gas supply,,but you have to burn more of it because it's in there!!

Especially if you're on vacation out of your homestate, you're bound to have to pump it in. Florida pumps too have been integrating 10% ethanol. No issues here.

Dust off your owner's manual ... it talks about what fuels are acceptable. Up to 10% ethanol (ethyl alcohol) is listed as acceptable. The alcohol will help keep your fuel system water free ... but yes, you will see worse fuel mileage.
Now the nasty crap they sell in CA might use wood alcohol instead of grain alcohol and some nasty anti-corrosive additives. Stay away from those fuels if possible.

Its required by law. They replaced the MTBE additive with Ethanol a couple of years ago. Although MTBE reduced exhaust emissions (not CO2) it caused water pollution. Another win for the environmentalists. They forced MTBE on us and then when it didn't work out they blamed the oil industry.

Ethanol is crap. I new magazine study showed that an E85 vehicle on E85 got 15% worse milage than a standard vehicle on pertol-based gasoline.
While it won't hurt your engine, your milage will go down.
Can ANYONE tell me if there's a good reason to have ANY Ethanol in our fuel?

Texas has had that 10% blend for a good while now. At least in Texas 93 octane is still widely available. Oklahoma is stuck with 91, pretty much throughout the entire state.

Working for a fuel distributor here in Fla everyone has gone ethanol. The why is that there are tax advantages from the feds, since it is made from a renewable source. There is allot less energy in ethanol than gasoline so you will see around a 10% decrease in mileage. Ethanol does "absorb" water, until it gets saturated with it, then it causes "phase seperation" where the alcohol/water will "drop out" of the gasoline, something you don't want in your tank. The ethanol will clean your cars fuel system and raise havoc with those pesky fuel level senders.

I agree. I used to be able to get 350+ miles per tank. Now it's down to 310. (same driving route and time of year)

The overall environmental harm from processing ethanol is more harmful to the environment than running straight gasoline.
