I've used Suzuki 2-stroke oil in my 150ss since it was new (1989) with excellent results. The place where I purchased it doesn't carry it anymore and I can't find it elsewhere so I'm looking for a new oil. I'd prefer one that's easy to find. What are your suggestions?? Someone told me to buy Arctic Cat snowmobile oil and it would be the same because they use Suzuki engines. Makes sense but I'm not sure what the rating of a snowmobile oil is. What are you guys using?
