Perhaps, but they both do the same thing. They get water out of the fuel. While it doesn't matter much in the Arizona desert in June, it does in Duluth in January.

I only buy fuel with ethanol. I also don't go out of my way to buy organic and I vaccinate my children. The internet is full of a lot of BS.

I agree!!




With respect to ethanol content harming the vehicle, all I can say is this......Along with the JGC, I also have a 2001 Corvette. I bought it new, and it's a low mileage vehicle. Because I'm a "maintenance freak", I replaced the OE fuel filter when the car was 3 years old, "just because".

About 5-6 years later, I began to smell gas fumes, but could never pin down the source. FINALLY, I stumbled on the cause. The "o-ring" on the output side of the filter was "seeping" gas, but only when the car was running, and the line was pressurized. I wasn't seeing any fuel on the ground, because as the fuel dripped, it fell on the hot exhaust pipe, which was directly below it, and the fuel vaporized before it touched the ground. I replaced the filter again, about 4 years ago, and it's been OK since.

HOWEVER, I also began using either ethanol free gas, whenever possible, and/or adding the Lucas Oil "ethanol anti-dote" to my fuel tank. My point? Although I can't prove it for sure, I think that the ethanol MAY have helped to attack the seal in the fuel filter, causing the leak. In all honesty, I'm very lucky the gas didn't catch fire.....
