Ethanol is mixed in the gas. It is not straight ethanol to my knowledge. And it's a small percent in there at that. I dont know of any cars that are specificly approved for that either. I can't imagine that it could hurt your car. I'm sure GM just had not tested it or found no need to and they put that disclaimer in there to cover them selfs.

Here's the lowdown on Ethanol fuel.

Older vehicles can't tolerate the stuff...period. Ethanol is corrosive in general to the plastics and seals by nature. It also tends to draw moisture, which in turn is corrosive in itself because unless the internals of the pump and the valves etc in the engine are stainless...they are going to corrode. Most of the new vehicles from the car manufactures can tolerate ethanol because they have started using the materials that tolerate it.

Ethanol in gasoline is basically a joke IMO, because while you're paying 10 cents/gal less, your fuel mileage goes down considerably. All my cars lose about 3-5 mpg's because of the 10% blended gas that's becoming harder and harder to avoid in Missouri.

The warning is to not run E85 (85% ethanol, 15% gasoline). A 10% ethanol mixture is what you'll find at most pumps, and that has been approved by all major auto makers to work in their engines.

The on base stations are now advertising absolutely no ethanol. I know where I'm buying my gas, as they're 5 cents cheaper than the off base 10% ethanol stations.

getting a reprogrammed pcm is said to require 91.so is this a good idea for a gt?

They say that because the timing is increased compared to the stock timing tables. A tuner is a good idea for your car. Pre-programed pcm's arent.

Thanks for all the info on the Ethanol, guys.

I'm really enjoying this forum, and I'm still trying to figure out all the abbreviations!

And thanks, Dohner, it's one of my favorite movies, too.
