pureboiracer 0 Report post Posted May 2, 2010 so i ran my racecar on 91 the other day.... big mistake.... runs like poo. I noticed that the mobil in paramata sells 98oct with 10%ethanol and was contemplating putting that in the racecar with a blend of avgas. (the chip sets the mapping to run somewhere around 100 oct). Was just wondering if mixing avgas with ethanol has any side effects or weather ethanol would damage my e30. Cheers oli Quote Share this post Link to post Share on other sites
