Termite would like to know if he can run 110 octane leaded race gas in an Echo Cs-590 with out any problems.😎
Ehhh thats debatable. I used to mix 110vp unleaded and 87 both non ethanol of course and all my stuff ran fine but no real noticeable gains. Now I have a 3 part methanol blend that is fantastic and gives a noticeable power and rpm gains. Smells good too lol.
