ive been using rotella 15w40 since the late 90s in all my atvs and motorcycles have never had an oil related malfunction since i switched. that said when i worked as an atv /dirt bike mechanic at a local dealer i learned a very inportant thing about factory spec oils the oems (honda/yamaha and even harley) use the absolute cheapest supplier that can meet their specs for the oil they put there name on and they change suppliers almost with the seasons. i have always heard and told others to find an oil that works for you and stick with it. just as an example i have over 4500 miles on an `09 rzr, 12000+miles on a vstar 1300, 400ex stroker i built in `03 stil lrunning strong with hardly any compression lossand still running original clutch plates, `04 scrambler 500 unknown hours. and numerous other atvs, dirtbikes and streetbikes all on rotella 15w40 without 1 single issue or problem and my stuff dosent sit it gets rode and rode hard the 400ex is on its 5th or sixth set of rear tires and i run them till there down to 15-20% tread. the only thing i ever noticed is on the RC51 i had a few years ago was the temp on mine ran slightly higher than my cousins and he used castrol activo but mine shifted smoother than his and never heard any valvetrain noise on mine but his would have a more pronounced chatter at idle. long story short find what your comfortable with using and change it often.




these 2 love riding in the RZR with us. cant figure out why the 1 pic keeps showing up sideways
