The 4 stroke Crosstour I purchased, last time it was registered was in 2023 so I am going to assume the fuel has been sitting in it for at least 2 seasons, I don't care if its E-free fuel or what ever kind of treatment it might have in it I plan on draining all of it out and starting with fresh. I would also like to put in first tank some kind of good fuel system cleaner. Is it safe to use something like my favorite automotive additive like Techron? Im not a fan of seafom, just curious what some of you guys might be using or using anything at all. Thanks!
