There is about a 5-7 cent a gallon difference in NC for E10 gas. When you say 25 cent difference is that E10, E15? I don't think our engines are rated for use of more than 10% ethanol blends/

Ethanol has 34% less energy than gasoline. So any ethanol blend will result in worse fuel economy in proportion to the amount of ethanol in the fuel. In the case of E10 that would be up to 3.4% worse mileage. Whether or not that works out economically in your favor depends upon the savings over lost mileage.

In NC when fuel is $3.85 (without ethanol) vs $3.80 (E10) then I'm only saving 1.2% while getting 3.4% worse mileage so economically it makes sense to avoid E10.

There are other potential long term drawbacks to using ethanol in your vehicle but Jeepers aren't the most gentle users of vehicles so YMMV.

I vote no to ethanol and avoid fuel stations that indicate its use.

I have never seen a gas station that has gas with no ethanol. Every gas station I go to has a sticker at the pump that says "Up to 10% Ethanol Added". Am I missing something?

Ethanol-free gas stations in the U.S. and Canada

I'm running non-ethanol now but probably not for long, as the nearest station is 12 miles from my house and as I mentioned previously, notice no appreciable difference.

Thanks! Holy crap, the closest station to me is like 60 miles away. Seems like this is more common in smaller towns? I live in the 2nd largest city in the state...

Absolutely the case.

California only has five stations in the entire state.

You can almost feel the scam.

The energy difference would result in about 0.5mpg less with E10 in a Jeep so it would be hard to notice but it adds up.

If you spend $3,000 year on fuel you'd be spending $100 more a year due to lost mileage from E10.

My expenditure will likely be closer to $750 for the year. Last year, I drove less than 2,000 miles.

Premium vs regular gas was on the pro side for the Wrangler in the pro vs con for my existing FJ or prospective new Wrangler. The FJ from 2007 to 2009 required premium. When Toyota tweaked the 1GR-FE in 2010 it changed, but up until then the FJ required premium. The manual FJ being full time 4WD had a MPG of 16.5. That was in San Antonio, after I changed the plugs. Because of the gearing, the 75+ mph that is common freeway speeds in metro Detroit was a killer on MPG; of course where speeds are MUCH slower in San Antonio it wasn't an issue. It is not uncommon to find drivers in the passing lane on the interstate in San Antonio driving 15 mph under the posted 60 or 65. Driving that slow in Detroit will get you shot. With the FJ in 6th gear, 2000 rpm will get you 60 mph. That 2000 rpm is on an engine that redlines at ~5500 and peak torque at 3600. In the Wrangler in 6th gear, 2000 rpm will get you near 75 mph, and that is on an engine whose redline and peak torque is about 1000 rpm higher than the Toyota. So my MPG is enormously better with the Wrangler AND on regular not premium. Fella, be happy you don't have to put premium in that filly and ride her until the sun sets. Yeee ha.
