Ethanol concerns

Ethanol concerns
Went to fill my truck at the Shell gas station I always use. Noticed a sign saying the gas, all types, has/is 10% ethanol, it was not like that the last time I went there 5 days ago. My concern is, can the 95 octane gas 10% ethanol be used in my MY99 911? It made no difference on my GMC MY99 truck.

Mileage
You might find you mileage drop. There was madatory 10% ethanol from November-March where I used to live. I had a Taurus SHO back then and my mileage would drop from 22 to 18 like clockwork when the ethanol mix was used. It just doesn't have as much chemical energy in it as plain gas.

^^^ There might actually be a tiny performance GAIN. Higher octane is a byproduct of the inclusion of ethanol in the fuel, though it would probably be imperceptible in an engine that wasn't designed to require it.

In my experience, yes. The guys who work on my car won't race with methanol enhanced fuels. Although the octane rating is increased by ethanol (octane is not a substance, it's a property of fuel), it seems like some DMEs read the combustion of ethanol as pre-detonation and react accordingly, retarding the timing and enriching the mixture.
I've told this story before, so I won't repeat myself here. But the phenomenon has been proven to my complete satisfaction, and I avoid ethanol enhanced fuels like the plague.

Indy cars have used ethanol based fuels for years......as well as methanol.
Sounds like the guys who work on your car were playing with you and seeing how much you would fall for.
