Ethanol-free Gas

Is anyone running ethanol-free gas? Any noticeable improvement in performance?

FYI:

36-mile drive for me to get 100% gasoline.

You owe me POS Racing :drive:

Noticeable improvement?

Power, no.

Gas mileage, definitely!

I use 91 octane E0 in my Miata, and 87 octane in all my small engines and tractor. I am running 0º BTDC timing in the Miata. I like to think it is helping, but I'm too TCB to do the dyno testing it would take for a definitive answer. I'm guessing about 8% more BTU's per gallon that the E10. But, with the stock '94 ECU, I can't tune for the fuel. What I can't find anywhere near me is E85.

There are two fuel stations in Gainesville that sell the E0, and there is one in Whitesboro. Once, while at one of the stations, a Prius with a NTTA toll tag pulled up to the pump and filled the car and ten (yes, that's 10) 5 gallon cans, put them all back into his car and drove off heading south on I35.

I rarely fill the tank and just drive somewhere. I normally just put enough fuel in to get to the next event. So, figuring fuel mileage is difficult. My back of the envelope says I'm getting about 7 MPG autocrossing, about 10 MPG on the track and 25 MPG pulling the tire trailer. I just don't know if the E0 is helping the MPG's or not.

I tested both (on a Honda) and made more power with E10.

This is pretty much the consensus on other car forums and BITOG.

Thanks cone-cerned! I laughed, I cried, I came away informed.

The station in Whitesboro is the closest to me that has 100%. I may check it out within the next month or so. I wonder what the Prius was up to...

Have you checked here for E85?

J/K above, David. Good to know that the E10 is helping your cause.

Thanks for posting. GRM's results supports David's experience. My hunt for 100% is over, and QT is fuel destination :)

Not do I not avoid E10 stations I add a few gallons of E85 in, more booooost!
