Gasoline that is.

Where i normally fill up (I fill up and pay at the end of the month); they only have a few pumps. There may be another pump across town with the same company that is 91, I'll have to check. Out of the following, would you rather run no.2 or no.3 in a 2013 GT?

1) 87 octane 10% ethanol
2) 89 octane 10% ethanol
3) 87 octane with no ethanol

I'm gonna look for that other pump tomorrow to see what else is available.

Thanks!

I'd probably go with #3

If at all possible, I prefer to put ethanol-free fuel in my Stang. But then, mine isn't my DD.

I've done extensive data logging between ethanol-laced and ethanol-free fuel on many long distance drives using fuel from the same stations and on the same 400 mile stretch of highway and have found fuel milegae to vary by as much as 4 MPG. Unfortunately, with each tank of fuel you buy with ethanol in it, you can never tell what the % ethanol is; it could be 2% at one fill-up and 12% the next. I know, "contains up to 10%..." but who the f*** is watching them?

i agree 3! anytime ethanol free go for it!

93 eth-free!

Sorry, I know those days are gone

Depends on your concern. Mpg? Go eth free. Octane? Go #2.

#3 or if you can find a pure gas station with 93 eth free thats even better!

Thanks fellas, really my main concern is just the health of the motor.

Ha, I've got 4 stations in my area with this, still slightly inconvenient at times but pump it if you've got it!

I'll be packing and down real soon!!

AND, double bonus, I've always noticed while driving the entire length of I-95 that SC has the cheapest gas
