After reading the FAQ, I’m confused with what type gasoline I should be running in my 2020 Mercury Fourstroke???
Since 2005’ish, I’ve always run Rec-90 with different types of fuel additives over the years. When I got this new Merc, I didn’t think twice about continuing to run Rec-90 w/ Don’s cocktail. After re-reading the fuel thread in the FAQ, it appears to suggest I should be running plain old 87 Octane gasoline for best performance…HELP!!
