Xps...
This past year, BRP actually came out with semi-synthetic oil that is usable in all the 4-TEC engines, even the supercharged.
The only supercharged engine I would not run this in, would be the ones still using the ceramic slip washers.
Check with your nearest distributer for the XPS summer grade semi synthetic oils. It would def be the best oil offered by BRP.
Now, if you'd like to spend a tad bit more money, for an oil that is tried and true, go to the
Amsoil website and look up your oil by make, year and engine model. If your still unsure, you can phone in and talk to a representative.
Amsoil has been a sponsored distributer of race oils for a long time. They also have their own research and development engineers to help you decide what forumula is best for your application.
I personally do not use this oil and don't recommend it for the 2 stroke engines. Only because there are so many good, synthectic oils on the market for the Rotax 2 stroke, that I do not see a need to promote any other oil brand.
The best part with the Amsoil, you can order it by quantity and not have to worry about where your going to get oil later in the season, you'll have the address as to where to get it.
Also, if you look around, you may find the Amsoil sold locally. My opinion of this oil is from the testimony of other members and they swear by it. I have never heard of anyone coming in after running Amsoil and find they had any kind of major engine failure. So, to make sure you always have a good supply of oil on hand, maybe you should look into ordering a bulk quantity of the Amsoil brand oil............:cheers:
