Alright guys I tried searching for a decent answer to my question to no avail. I have a '13 JK sport, It is my daily driver getting ~12K a year. My local gas station offers Ethanol Free 87, pros and cons on using it? Can I use it? Should I use it? Thanks!!

I would kill for ethanol free gas - Yes, use it. Ethanol is crap. "Technology" in the form of grain subsidy to corn farmers. No disrespect to Farmers (Love them, need them depend on them) just don't want to be forced to burn it in my rig.

Pros: Doesn't suck
Cons:
------
I used to run ethanol free in my old motorcycle, 'cuz the ethanol would turn to jelly when it sat or got cold and f!ck up my carbs.

I look at it like this.... ya know that E85 stuff? They make engine parts/seals/hoses specifically to handle the ethanol. SPECIFICALLY FOR THE ETHANOL. They tell you not to put it in the 3.6 Jeep engine (even though it's the same base engine in their minivans that IS E85 compatible) because those parts/seals/hoses aren't being used.

So here we have an engine that's not made to run on ethanol, and then they go and put ethanol in the freakin' gas anyway.

Also, ethanol has less energy than actual gasoline, so you might get noticeable, though small, improvements in mileage. Go with ethanol free, when you can.

This is not true I document every drop of gas it goes into my Jeep and for two tanks straight I pay $1 extra per gallon at a specialty fuel supply for ethanol free and there was absolutely zero change miles per gallon and no change in power or drivability as compared to the standard 10 percent ethanol blended fuel.

Ethanol free gas is better...gasoline has more energy than ethanol, which translates to better fuel economy. But it also costs more than E10, so you have to do a little math to figure out which costs more per mile. More expensive gas & more MPG vs cheaper gas & worse MPG.

Modern vehicles are designed to run E10 safely. Older vehicles have issues. Ethanol supposedly eats away at zinc, for example, and guess what Holley carbs were made of until the 90s. I make a 15 minute drive for ethanol free gas for my C2 Vette.

I paid $0.24 more per gallon this morning for ethanol free over regular. Besides the slightly better gas mileage, you get a fuel that is quite potentially less harsh on your vehicle, even if it is designed to run ethanol fuel safely. I'm no conspiracy theorist, but remember car companies are in the business of selling new cars.

Buying quality ethanol-free fuel is worth it whenever possible to extend the life of the Jeep and get the mileage bump.

It's not in use because it adds anything to cars...it's because it's more renewable and makes people feel good about getting off foreign oil dependence and oil in general (and maybe lower pollution).

The reality is that turning corn into fuel takes far more energy than doing it to oil, same with the impact on the environment from the respective industries. Sugarcane is actually a much better option (and what's used in other parts of the world) but we don't even use sugarcane for sugar anymore in this country...we use corn.

Weird, huh?

Thanks for all the input everyone. I assume with these answers that it is safe to run Ethanol Free fuel in my JK. For only 0.20 cents more per gallon and it being 87 I think if will run that from now on. Always heard Ethanol was bad for seals and gaskets in an engine, just didn't know if this was safe on our engines.
