ISO Heet for '05 900 efi

[bowerman61028]

Has anyone had any problems with using ISO Heet in their sled's first tank of the season? I want to make sure it is not going to damage the efi system. Also the bottle says it treats upto 20 gallons so should I only use half the bottle or dump the whole thing in. My tank is dry and I'm about to fill it up for the first time since April. My uncle swears by this stuff but I have never used it before.

heet

I use it in my efi all the time. I use the only the red bottle,this is what I was told. yellow heet is not intended for two strokes, I use about 1/4 of the bottle everytank when the temp drops.

I always premix my first tank of the year 100/1. I am a little scared of using auto additives in smaller 2 stroke motors ! And what is your purpose? Isnt heet used for removing water from fuel?
