Contains 10% or less of ethanol

This has probably been beat to death.

FACT - 10% blend does not lower mileage (tests by ISU and others have shown that - I could get you documented proof if you like.)
IF you have run-ability or mileage issues with it then you have OTHER issues, it's not the ethanol, the engine isn't well adjusted.  Any differences are easily tuned out, but I know of no one who's seen any differences that's I've heard where it can be PROVEN and documented and shown in scientific tests with "controls".
Fact - it will NOT damage any current engines or engine components in any way.
Fact - it will not damage any "classic" engines in any way as long as things like accelerator pumps and other "soft" carb parts were replaced between about 1975 and current.
Again, because of the octane improvement by adding ethanol, it can actually make things better. It will keep things cleaner, and there's less chance of gas line freezing.
Back in the mid-70's, auto makers updated their carb parts and all kits and replacement parts were made to be compatible with 10% blend.
Why? Iowa has sold 10% ethanol every since the late 70s/early 80's and in fact, you wil not find a station that does not have it!
It's about 14 cents cheaper here, and it's 89 octane instead of 87 octane, and it actually often does reduce ping because of the improve octane.
there's no "be careful" to it, period.
i've been fighting those myths since about 1977. And that's what it is - myth and hearsay.
Iowa law states that it's 10%, not "10% or less". It's got to measure 10%.  See-  it's been our daily fuel for a couple of decades.
I've run it in literally EVERYTHING I have owned since it became available - everything - chain saws, lawn mowers, trimmers, 1936 F20 tractor, all cars including the Eagle, Camaros, trucks, the jeeps, etc. I buy nothing else and have bought nothing else for decades - WITH one exception - at times I run a tank of premium through the Javelin, and now with the dist changes, will have to run premium most of the time, and it's not available in 10% blend, but that's the only exception)

10% ethanol has been sold as the primary gasoline here in CO since the late 80's (apparently it burns cleaner, because when the state Congress mandated that only 10% ethanol would be sold in above 4,000' elev. in CO it was with the intent of cleaning up the air). It used to be something that would only be sold in the winter months, but now 10% is all you can find here year round.

We were talking about 10%, so I left E85 out of it as that's a TOTALLY different animal.
We run the state cars on E85, and not only is there less mileage, there's less power, too.
E85 is a different topic and we've had complete threads here just on E85 and the pros and cons.
But for 10%, run it. It's fine.
I like it, it's cheaper IN IOWA due to tax advantages (well, we call it that but it's not really exactly or technically that......) and due to the higher octane and other good properties.

yeah, bill, the rumors, all false, of all the negatives were all people seemed to believe.
As a technician during those early days, I learned all about it in classes and "on the job".
And my experience with it over a 30 year time...........

Today, you see the imagined negatives popping up again because of some VERY well funded negative ad campaigns........ look into where the money is coming from.... (no not Exxon, etc.)
Oil producing nations and POLITICIANS! Guess the states those politicians are from........ but that belongs in that bazillion page thread m-m started LOL
