Snowmobile oil for KX?

(1/3) > >>

fullbore55:
I was wondering if anyone has ever attempted to use 2-stroke snowmobile oil in their KX?  I found a full case of Artic Cat 50:1 2-stroke oil in my basement from several years ago.  I don't think the oil will "go bad" but I'm not sure if snowmobiles rev as high as a KX.  Any ideas?

I will be watching this with interest. I sold my snowmobile a couple years ago and still have a gallon of 2 stroke oil left. I asked my Honda dealer if it would run Ok in my 2T bikes. He said no reason not to. I still have been hesitant in trying it. I hope someone who has tried it can give a definitive answer to your question. If it is OK I would think running it 32:1 would be a must. I suspect it will not run as clean but that is not based on any real knowledge on my part.

The big difference with snomobile oil is that it is designed to run at a much colder temperature than normal 2-cycle oil.  It is often designed for injector systems as well, and therefore is thinner to run through the injector system at cold temps.  My vote is no.  It will work but I have found out long a go that the "cheapest" oil to use in the long term is always the BEST oil.  I wouldn't feel bad about running it in my weed wacker but the KX not. Hope this helps. Cam.

 I second that. It has to be thin. There are alot of two-stroke oils out there, but I prefer synthetic. See if you can sell it to a fellow snow mobiler and use that as a discount for some real good oil. Remember your cylinder and crank are lubed by the two stroke oil. This is not an area for changing things around. Quality high octane fuel, and your two stroke oil should be a constant to keep bike tuned and to eliminate variables in tuning issues. Even if you change two stroke oils that are both high quality synthetics, you should completly drain and rinse gas tank and gas cans to avoid any adverse reactions. ( Just my own theory on that)  :wink:
