I get worse gas mileage with E-10.

 

every pump i have ever seen to date has a sign saying "can contain up to 10% ethanol"
I never had a problem with it.

 

e-10 everywhere here in indy, no issues.
if you keep everything tuned, esp when changing setups, there should be no worries whether it be normal 100% gas, E-10, e85, etc.

 

Here in the midwest its been E10 for probably... 10+ years. Good for the environment, doesnt change much for mileage, not a big deal.

 

i dont liek it but they put that crap in everything nowdays

 

You'll be able to run more boost on it. You'll go through it quicker. Other than that - I don't know why everyone thinks it's bad. 20% would be even better!

 

The more the ethanol, the more the boost!

 

OK E-10 or 10% eth. with fuel..yes it lowers the crap our cars belch out but does it really? you get worse mileage on e-10 unless you play with your tune to get the lost mileage back.
We get 100% gas here in spring/summer and e-10 in the cold months..I drop lots of gas mileage during winter, I'm down almost 30-40 miles per tank on e-10. I now have tunes for summer and winter..I gained back about half of what I lost on e10.

 

People are right. You'll get a bit worse gas mileage but should be able to make a bit more power. The ethanol works as a good knock quench so you can up the boost a bit and/or raise timing.

 

MA has had E-10 for a while. I get 21mpg around town, and 26 all highway. This is without being easy on the car too tuned to 26+psi.

 

the 10% ethanol allows the gas refiners to cheapen (weaken) the gas, using the ethanol to maintain the octane rating.

for that reason you will be hard pressed to get a real benefit from the ethanol.

the net of it is, a boon for ethanol/gas producers via tax incentives and regulations. no real benefit to the environment or consumers, a straight out money grab with a green coat.

unfortunately that is what all enviro mandates will be. business (buying) government to make regulations forcing us to buy green products. the net environment benefit is next to nil.

look for the money trail, no one wants cap and trade more than the super conglomerates, same goes for all the green coming our way.
