Re: E10 Fuel...Is it any good for these motors?
E10, or 10% ethanol has been around here since the '80s. As far as i know, just about everything manufactured in the last 25 years is designed to use 10% ethanol.
Now, that being said, is it better? Nope.
A different question- Is higher octane going to do anything more than add placebo effect speed and smoothness at any compression below abot 9 to 1 (probabky higher, but I'll give the benefit of the doubt)? Nope, but if it makes you feel better, we use so little gas the cost difference is insignificant.
