Ok, I have read a hundred articles on this stuff, some say yes, others no.. So I will ask my most trusted source for some help. I store my sled in a heated garage all the time, so it is constantly going warm to cold to warm etc.... Should I use the Iso Heet... I bought a red bottle of it, and am just curious if others are using it also? Thanks for any help.
Iso Heet?

One other thing, is there only one type (blend) of Iso Heet? Which is the red bottle. Then Heet is in the yellow bottle.

If you run nothing less than 91-93 octane without ethanol then you should use isopropyl alcohol in your fuel. If you run any fuel like 87-89 octane with ethanol then you should not use any. Dont run Heet in the yellow bottle. You can run Iso-Heet in the red bottle or Isopropyl alcohol in the white bottle.
I always run 91... so I should use? I dont think the premium 91 up here contains any ethanol?? I know 87 and 89 contain up to 10%.
I agree with chunky. It is even more important to use when going from the conditions you mention. If water forms from this, or snow ingestion, it can clog your jetting and cause a lean burndown. Also, it is best to put your sled in a warm garage when the motor is still warm, rather than to let it set out and to put it in later (cold). Just a tip, hope this helps!
Yes, use Iso if no ethanol.
thanks for the info guys... just to clerify there is only one "blend" of ISO Heet corrrect? (All Iso Heet is the same) The bottle doesnt give much information that is why I ask, I have the red bottle.

I also use the red Iso when I'm in the mountains and run 87 non ethanol. That reminds me need to get a few of them before I head west next Tuesday.

I believe so. I dont think there is more than 1 type.
Well I guess the ISO in Iso Heet, stands for Isopropyl, so as long as it is isopropyl based i guess it should be ok, lol. Thanks for all the info guys!
