IIRC reading through other posts, regular unleaded 87-89 octane is the recommended fuel. Flex fuel (AKA ethanol E85) is not recommended.
E15 is fine. Anything higher than 15% ethanol is not. This means virtually any regular pump gas you'll find on the road is usable.
Yep I have a giant Buccee's about 5 miles from my house rows and rows of ethanol free gas. Its the only place I know around me that has it. I have to pay a bit more for it. Could all just be in my head but seems my truck runs a bit better on the ethanol free gas
E10 is about 3% less energy than pure gas, e15 about 5% so you should see about 3% better gas mileage than just the normal 87. Makes it easy to know if the e15 is a good deal too, it needs to be 2% cheaper versus the e10 to make it worth while.
Well, sort of. But e15 is also slightly higher octane, at 88 vs 87. Around here, e15 is sold out of blue pumps, at 88 octane, and e85 is in yellow pumps. "Regular" unleaded is in the black pumps, and at "up to" 10% ethanol.
Commonly called U88 - it's absolutely fine. It's defined in Iowa as having "between 12 and 15% ethanol"
Most stations don't have U88 or "E 15" Most have 10%, and here that's defined as having "up to 10% ethanol". 15% is known by U88, which is "unleaded 88 octane" and they get the 88 by going up to 15% ethanol.
Yup - I've been running it for months. Every since the newer Casey's stations started selling it. 10 cents cheaper, and my truck does great on it. My MPG hasn't dropped even a tiny bit (university studies show no differences between 10 and 15% in mpg, it's when you get 20 and over you look for differences)
