What's the true octane level of E-85?
The pump says 105 but web pages I've read say between 94-97. Just don't know what to believe.
The real octane rate for E85 is 95.8 in the US. This rate varies from one country to another. The ethanol rating is 113 while the anti-knock index is 104. You can get some information about E85 on http://en.wikipedia.org/wiki/E85.
