Alcohol (Ethanol):

* Is subject to phase separation, which happens when the fuel cools as an aircraft climbs to higher altitudes. When the alcohol separates from the gasoline, it may carry water that has been held in solution and that cannot be handled by the sediment bowl.
* Reduces the energy content of fuel. Methanol has approximately 55 percent of the energy content of gasoline, ethanol 73 percent. More alcohol equals reduced range.

So, if ethanol is so great, why don't airplanes use it?
I hate it too, Ive gone through two cases of fuel filters ever since its inception. and I cant even start my car when its cold outside either.

Alright even more evidence is out:

Whether it makes sense to use ethanol as an alternative fuel is a hotly debated topic. Consumer Reports tested a Chevrolet Tahoe flex-fuel vehicle running on E85 and gasoline, and found that its fuel economy dropped 27 percent, from a poor 14 mpg overall on gasoline to a dismal 10 mpg on ethanol. Even though a gallon of E85 ethanol costs less on average than gasoline ($2.13 nationwide average this summer, vs $2.44), it would cost a consumer more than $450 a year extra to fuel the Tahoe with E85 instead of gasoline due to the fuel economy differences.

So not only are we getting screwed in the wallet, we're also having mechanical issues.

Does anyone know if there's ethanol in PREMIUM gas?

Valero owns 7 ethanol refineries, they do in fact use ethanol. All domestic gasoline in this country should have 10% ethanol in it.

You're right. I was wrong. I had one manager telling me no ethanol and then I tested it myself and it contained ethanol.

Now, one place that does not have ethanol for sure is CITGO. I would never support them, though.

Citgo uses 10 percent water to make their gasoline last.

I tired Valero Premium my last fill up, and I did not like my WOT runs, now I recently filled at Texaco and Its been running great. Still might have ethanol though. but didnt notice, performance wise.

By old cars having problems, what do people mean by that? Ours are 2000 and 1992 year models and no problems so far... I'm not sure when 10% ethanol started showing up in the northwest but it's been at least a couple of years now that the cars have been running it.

The NuStar loading rack near Kirby ships some non-ethanol automotive gasoline, but I have been unsuccessful finding out which retail outlets are receiving the non-ethanol product. I will keep working on it, and will post here when I have some solid answers. - Slowpoke (tanker truck driver)

There were four San Antonio gas stations on pure-gas.org that did not sell alcohol laced gasoline. The latest details (including one posted by me for the Shell at Fredericksburg Rd @ Huebner) shows there is no ethanol free stations left in San Antonio.

It is BS that it affects MPG only slightly. My MPG has gone down more than 10% with this crap in the tank.

Check out this website: Ethanol Blended Gas = Lower Mileage?

Last year with Shell 100% gasoline in my tank, I drove my Corolla to Dallas and got slightly better than 42 MPG. I drove it earlier this week with Shell 10% etahnol blended gas and got 35 MPG.
