It's a bunch of internet conspiracy bull**** that started several years ago. Most pollution controlled communities with emissions testing have had 10% ethanol since disco was hot in the 70s. Back then it was called gasohol...it's called gasohol in my 928 owner's manual. I was a kid when all the little corn emblems started to appear on fuel pumps in my area. Many got their panties in a bunch and months later when nothing happened, it was all forgotten about. A few years ago when it started making rounds on the internet as if it's something new and horrible that is sweeping the nation.

My favorite are those who insist their owner's manual clearly states to never use ethanol. What it actually states is not to use METHANOL...but hey, it sounds close enough to ethanol so it must be the same.

I started driving in 1986 and I've never owned a vehicle that was not exposed to ethanol. My 928 came out of Chicago and it's been using it for 34 years. My lawn tractor is put away every fall and starts fine in the spring with the 6 month old gas every year for the last 14 years. My snowblower is put away every spring and starts fine every winter and is also 14 years old. The fuel in my generator is often 2 years old before I need to refill it. I NEVER use products like Stabil. I've NEVER had to replace a fuel line or touch a carburetor on any of them. Engines have never needed to be opened, I've never experienced a burnt or carboned up valve. I have two rare 30+ year old FI turbo charged motorcycles that have also had nothing but 10% ethanol their entire lives. Same with air cooled motorcycles, 2 stroke engines and the Corvair I drove into the ground over 14 years.

When I have a problem with any engine, the last thing I suspect is a fuel system problem. The whole ethanol scare is nothing but a scapegoat for a million other problems.

As far as E15, it's not some government mandate. It's an OPTION for 2001 and newer cars and the government is ALLOWING the gas stations to sell it. It's an option same as choosing 87 vs 93 octane fuel. I highly doubt we'll ever see the day when it replaces E10.
I'm also allowed to choose what fuel to use in my new 2014 E350 Super Duty. I average 13.1 mpg with regular fuel and 12.3 mpg with E85. Hardly the 3 to 4 mpg decrease that so many people claim.
