We use Extreme oil in all our sleds old and new till last winter I bought an etec and used the ski doo semi syn in that, bought 5 cases Extreme 3 years ago and have 3 gallons left, it works great and minimal smoke or smell!

With the discussion regarding fuel I thought this would be a opportunity to ask my question. I am a recent Rupp purchaser and was wondering what is the best fuel. This is my understanding: My Rupp is a 1971 400 Magnum. Mix 40:1 Oil: currently have Klotz. Octane: What is best? Some sources have told me to use as high as possible. Up to 100 Octane. Ethanol Free: In winter in Michigan where is a place to get ethanol free gas and at that octane? I have found 90 octane ethanol free gas this summer at a marina, but they won't have it in the winter.
