Re: FLEX FUEL with OCTANE BOOSTER?!
I've used both regular 87 fuel and the E-85 fuel since I've owned my Jeep. So far, I noticed a slight decrease in MPG with the E-85. But at the sametime, I feel the Jeep performs much better on the E-85 than standard 87 Fuel. Seems much quicker and more responsive. That may be because of the higher octane rating.
Anyways, to me the E-85 makes the vehicle run better and more enjoyable to drive. But I still use 87 fuel as my weekly fill ups until the price goes way up, then I shift to E-85 until it comes back down.
