The use of SM or GF-4 rated oils was prohibited by BRP due to the friction modifiers some manufacturers used to achieve those ratings. Some of these were "too slippery", causing clutch slippage. Since the Spyder came out, the situation has become more confusing. First the Rotella-T, and now the Mobil1 4T, have changed their rating to SM. At the same time, though, they carry the JASO MA rating, which has been contrary to the SM rating in the past. My guess is that they are achieving the standards through a different formulation, that now allows the oil to meet several accepted standards.
The successful use of these oils is the key. If you have been using the newer products with no clutch slippage, you are probably OK...provided you do not have a lubrication related failure that needs warranty repairs. Use is still prohibited by BRP. I know some owners have had problems with the new-label Rotella-T, but they may have used 10W-40, which is a different formulation. I think our best bet is for owners currently using the rerated oils to report on their success or failure, and the specific brand, weight, and rating of oil they used, as well as how many oil changes they have used it, so we all know what is working in the real world.
Scotty I Pasted this from my former li nk-
A premium quality motorcycle engine oil can be stated to meet the requirements of API Service Classification SJ, SH, SG, SF, CH-4, CG-4, CF-2, CF and CD. Note that SH, SF, SG and CD are now obsolete. Motorcycles specifying an oil meeting any of the obsolete applications can use an oil with the newer classification oil because it includes, and supersedes, the requirements of the obsolete service classification. For example, if you have an old motorcycle that specifies SE service classification you do not have to go out and look for an oil with that service classification (and if you did you would most likely not be able to find any in stores as SE was outdated in 1979). The newer classifications include the outdated ones and are perfectly suitable for use. There are some motorcycle oil manufacturers that will include an older service classification on the bottle to so that consumers can specifically see that the oil not only meets all the older specifications but the newer ones as well.
Mobil Superceded the old SG, SH with the new SM rating. BRP has NOT!
