15% Ethanol Will Damage Your Classic Porsche

Recommended Posts

Because of the danger of ethanol gasoline on older vehicles (in fact Porsche recommends against even 10% ethanol in cars made before 1996) and with the new 15% ethanol gasoline causing many manufactures to void warranties if the new 15% ethanol gasoline is used (some are cars as new as 2011), we must band together to keep our cars running. In the comments and on some forums that have been talking about this original post many people recommended that various automotive enthusiasts from clubs such as the Porsche Club of America, Porsche Owner’s Club, Corvette Club of America, Ferrari Club of America and many other clubs band together to stop this. SIGN THIS PETITION!!!

I have done a bit of research on some Porsche models using 10% ethanol fuel and ethanol free fuel. The car we did the most testing with was a 2004 996 Turbo. Though we have also done some testing on a 89 964, and a R56 Mini cooper. The results really surprised me. Using our chassis dyno to measure we found that on all three cars we saw higher performance with the 10% ethanol fuel. With the 996 Turbo we tried a lot of different tests using fuel from multiple sources and with different tunes on the car. Not only was the 10% ethanol more powerful it also was easier to tune a more consistent mixture then using the ethanol free fuel. I also signed the petition for the older cars having problems with it, but I will continue to buy ethanol fuel and look forward to testing the 15%.

I am running E85 in my 79 3.0 turbo conversion.  No problems as of yet.  Although my car is far from stock.  I am able to run more boost, and a much more aggressive timing advance with E85.  BTW, my compression ratio is 9.5:1
