You sure about that? I know when I went to E85 and the GM truck was designed to do that, the power went down to the toilet. You see, when I run a tank of gas, I run it to the bottom so when the new gas comes in, I know whether it sucks or not. Power went straight to the toilet as did mileage. In fact, it seemed to cost me more to run E85. When that tank was done, I filled up with some good stuff.
I think it might not be so noticeable if you drive say 50 miles. I think long distance and towing might show that you lose more than you save.
The only way I would run a lower octane is if I had to and fill up enough to get to the next gas station.
Yes Ak,
we are on the same side of this one....
I agree ethanol sucks - even for those that have e85 engines...
the diff in octane rating is what I was referring to as robbing the engine of power...
I ran a turboed gas engine that called for premium for years on regular with no issues other than a little less oomph.... and when I went to the track, just put prem in it before to restore the few hp it lost...
The crystal ball asks what's going to happen when premium gas is banned by the EPA to save the environment ?
