Dealer did my 600 and I did the 3000 before Rolling Thunder it was going to hit the mark between here and D C. Anyway I do find it somewhat bothersome that the BRP jugs don't show a rating for the oil, but the book as I recall (it's at home) does specify either semi or full synthetic rate JA2. I'm planning to switch to Amsoil with the next service and will likely switch the wife's Ural over to it also.
Ride safe,
Here is what the manual says for my 2011 RT-S
Recommended Engine Oil
The same oil is used for the engine,
gearbox, clutch, and the Hydraulic Control
Module (HCM) in the SE5model.
Use the XPS SYNTHETIC BLEND OIL
(SUMMER GRADE) (P/N 293 600 121)
or a 5W 40 semi-synthetic (minimum)
or synthetic motorcycle oil meeting
the requirements for API service SL,
SJ, SH or SG classification. Always
check the API service label on the oil
container.
NOTICE To avoid damaging the
clutch, do not use a motor oil meeting
the API service SM or ILSACGF-4
classification. Clutch slippage will
occur.
