Ok peoples, I just put my car on pump gas the other day and I was surprised by the gas mileage that I got back, with that said I have been thinking about pros and cons of E85 vs pump and meth.

Now during the "season", i drive the car everywhere, hell as long as the salt isn't down I drive the car basically.
My feelings are that E85 is too inconsistent in MN, but I really haven't had any problems I would just take my laptop with me and make a global change if needed, which was usually every monthish.

The reason I see the pump/meth being better is consistency. I can tune the car and forget about it, i love scheides setup for meth seems to be trouble free once tuned.

Hopefully the pro tuners will jump in here and give their .02 cents worth as its about $2mil to me. And of course people that have had experience with these diff. types of gas and tuning with them.

Final word, I never did really get into "lean burn" tuning on E85. Maybe once I have the car pro tuned on E85, compensating for the diff. blends would really completely be just a slight global change. Please note that I like to tune very conservatively.

Thank you

Pump got my vote. Better gas mileage, no worries about searching for E85 stations when you're traveling, more consistent, etc.

I've also been thinking about switching to meth recently. The only thing is that where I live there isn't any good 92+ stations, but we do have a couple decent e85 stations.

But I must say I do like e85, just wish it was more consistent.

^^^^^ like jake said it would depend on ur area moreless. Our area has shit for decent pump gas only 1 Shell station in hutch and one in glencoe, but e85 is readily available in our area, and there isnt much variance in the blend that i could notice on my wideband.

And I think that shell just has non-oxygenated garbage 91. I havent been there for a few years so that might have changed.

in hutch prolly we got the v power 92 here in glencoe, the bp here in town has the non oxy 91 or the bp93, but e85 is just as readily available.

shell is usually 92 and is junk. I'll only run bp 93

E85 for sure.. I dont wanna have to get the meth kit and fill it up all the time. To much of a hassel for me. I have more than 1 car so if its not a Mitsu Cruise that im on I can take my other car if E85 is not available.

I'll probably just do e85 and have shane tune it cause I don't need to buy any extra parts to switch to e85

I have tuned with both premium fuel and E85 and E85 is much more forgiving. I haven't tuned with meth yet.

For lean burn or leaning it out, I have went to 18:1 (WB not adjusted to E85) just to see what it would do and I got 21MPG but it felt pretty lean and couldn't have been that good for the car. Drove with little problems though.

It goes back to the question of, are you going to be using the car as a DD or a weekend car? if a weekend car E85 all of the way. It would be cheaper to run Premium on a DD though
