has anyone started a thread about this or has anyone perfected a good homemade mix that seems to do the trick?
getting sick and tired of running watered down 91 pump gas....
 
You'll get tire of mixing the gas in the long term, Used to have 93 around and now most gas stations have 92 so im just hanging with 92. If looking for performance, you'll need a tune and once thats done, you'll need that gas at all times. Let us know how that works your MSP.
 
if the nation would only make it easier and roll back to non ethanol 93 octane fuel.....
