Brian, here is a link to a page with their Ski Doo oil (same as for Sea Doo). I stand corrected, their price is not that much less than dealer. I must have been looking at the synthetic blend rather than the full synthetic. The blend is $25.99, the full synthetic is $33.99. That is not a bargain at all. Pretty much what I pay at my local dealer, and you would have to pay shipping with Shade Tree. I am not sure if I am going to try the synthetic blend for my Sea Doo, will probably stick with the full synthetic to be safe. Again, a bit more expensive, but the piece of mind is worth it to me.
