In 2-3 occasions I have used E15 to test... as a matter of fact, I just filled with E15 last night when I left from work... But the few times I have used it I have not noticed any significant losses... after all, most of us have already been conditioned to E10 @ U.S. pumps across the country... I can't find any station near me that caries ethanol free gas for several years now.

I have only recently in last few tanks tried to fill consistently, hence the big tank to tank swings. E15 is $0.10 cheaper so basically 5% at todays prices with at less than 1% mpg loss worst case. They removed the 87 octane E0 that was $.40 higher than E10.

Anybody else using it?
No E15 in our state for at least 3 years, there was e20 up until about 2 years ago, all the blenders went bust in Wisconsin,
backtracked 10 years in the process.

(DIC indicated 45.4)

After making sure my co-workers weren't messing with me I've decided the pump must be out of calibration. Going to go get a 6 gal jug and fill up a lunch and see how much gas fits in. I'm thinking it will be 4.5 gallons.
Make sure you turn them in for shorting their customers. They should be made to refund the money they got for the short gallon.
