Better MPG when mixing gas???????

now i have no clue how things work in the US. i think for the most part you are stuck with ethanol gas unless you can find somewhere that sells ethanol free gas and that is very hard to do.

ALL the major oil companies use ethanol in gas - regardless of octane and get HUGE supplements from the federal government to do so (our tax dollars at work again, LOL). It's usually the small independent stations who offer ethanol free gas and these stations are becoming rarer.
It should state on the pump if ethanol is used or not, either stating "10% ethanol" or "E10"...

guess I need to be getting me some startron, and should I use it for every single fillup?
Do you think that will take any worry out of filling up with just 89? As in in case its watered down or not the best batch.
Thats really the only reason I mix mine, not to save money or anything but just more of a safety factor put in place there.

i was just meaning should I stop worrying about going over 89 because worrying about it being a bad batch of 89.
Like I said we dont have 91 around me, and im not opposed to paying for 93 but it just seems like overkill. I know some people say it wont harm a thing but still.

Yes, whether you choose to buy StarTron or a similar ethanol treatment product, use it in every tank.
As far as the octane you purchase goes: It's well documented around here that I firmly believe Chrysler should remove the "89 octane preferred but 87 is ok" out of the damn owner's manual. The compression of the engine dictates you should use 89 octane and NEVER use 87 octane.
91 or 93 is not necessary (with a stock tune) and won't give better results (unless you are towing/hauling or working your engine very hard). Won't hurt a thing, but will cost you a couple bucks extra you don't need to spend.
Obviously, if you have an aftermarket tune, then you must use the octane fuel that tune recommends or higher...

If this helps try pure-gas.com. closest one for more is the EZ STOP in St. Leon, IN. thats 33 miles from the house. They use Marathon fuel. Its 90octane w/ no ethanol. After my 2nd fill up saw an increase from 18.2 to 19.7 on the highway at an avg. speed of 70.2mph. This has been thru my GPS and hand calculation.
