Re: TuneUpTutorial
I checked the site out & it has a lot of info on it, but "octane" puzzles me. In on area he states never use "87", in another he states never use "premium", use mid-grade! Unlass you trailer the boat, you can only get mid-grade on the road. Most marinas only sell premmium. Now my engine manual states any are "OK". Anyone care to comment?
