is it ok to run 10% etahanol with a tune? can get 94 octane here but it is 10% ethanol.

 

yep

most places in the country have 10 percent in the gas. just stay away from the "E 85" unless you want to make fuel system upgrades/repairs

 

Better to not have ethanol, The only 93 octane I can get is also 10% ethenol, so I stick with the 91 octane tune.

 

Why, what is wrong with ethanol?

 

Never heard of anything bad about ethanol being in the gas... Keep in mind the millions of cars that use the ethanol gas, a mass-produced everyday car like the Mustang will be the last to have a problem with it.

Where I work we have a large fleet of trucks and per government regulations, 90% of our fleet has to run on E85. We are currently in the process of auctioning off our Rangers as they had alot of problems and we are replacing them with F150's. Most of the Rangers ran on E85. They all have constant problems with gaskets, certain parts melting, just alot of drivetrain problems. The ones we ran on 87 octane had nowhere near the problems. We also have some full size F150s, Rams, and Silverados, also with problems with E85. The same engine can also run on 87 octane. The ones on 87 run and last so much better, they don't see the garage near as much.

E85 doesn't get near as good mpg either, so the price difference really doesn't do much with more problems and less gas mileage. A good friend of mine also has a GMC Sonoma, which he was craxy about E85, until he started having problems. His engine started ticking and he started getting catalytic converter problems, just like the Rangers. I don't use E85, so I can't speak from personal experience, but seeing the reports from the garage about the fleet, and seeing my friend in such bad moods just from driving his truck back and forth to work, it's just not worth it. Maybe one day, but from what I have seen, I think hydrogen will find it's way into vehicles as a regular type of fuel faster then E85. just my opinion.

Right, thats E85. But the guys above are talking about regular gas with ethanol in it.

 

but ethanol gets only about half the MPG of gasoline, so if you are running 10% ethanol, that's a significant drop in MPG. I don't see any price breaks for running 10% ethanol either. It's $3.30 per gallon no matter what you buy.

I kick myself every time I see "10% Ethanol" hidden somewhere on the pump.....I always see it after I fill up.
