I just added some Heet water remover to my fuel tank, 90HP 2004 Johnson(oil injection) outboard. Then I read Instructions. "o Not use wiyh 2 cycle gasoline .....on the back of plastic bottle. Called their 800 number to see what i might do. Only answer i got was to empty fuel tank (27 Gallon internal). Use other red bottle treatment.
Can I add something to counter act, or is it ok to use with oil injection?
