The oil I sent in was the second oil change on my 2014 RTS SE6. The first oil change was done by the dealer at 3k+ (about 3,300). The dealer changed the oil, filter and performed the bike's first service installing BRP's 5/40w syn/dino blend oil as recommended by BRP. The second oil change was done by myself at 9,500 miles. So, I ran BRP's 5/40w syn/dino blend for approx. 6k miles and that was the oil I had tested. The results were as follows; (ppm) Preformed through Napa Oil Analyst by U.S. Laboratory in Portland, Oregon
Metals - Iron 19, Chromium 1, Led 3, Copper 7, Tin 3, Aluminum 11,Nickle 1, Silver 1, Titanium 1, Vanadium 1,
Contaminants - Silicon 13, Sodium 9, Potassium 4
Additives - Magnesium 59, Calcium 2036, Barium 1, Phosphorus 725, Zinc 798, Molybdenum 1, Boron 11
Contaminants - Water% 0.05, Coolant none
Physical Tests - Viscosity (cSt 100cc) 8.5
Physical/Chemical - Base Number (mgKOH/g) 4.9
Analyst showed **Caution
According to Bob the Oil Guy's oil chart, BRP's 5/40w syn/dino blend oil viscosity continues to decline in viscosity as millage increases. This has been confirmed by BRP saying that their oil declines to 20w and then stabilizes at some point. More independent tests should confirm that info but in the mean time I switched over to 10/40w Amsoil. I'll post my next test after I run Amsoil for 6k miles.
