Amsoil vs polaris oil. Never had any problems. AMSOIL INTERCEPTOR delivers, and here's the proof. The 2- or 4-stroke engine in your sled works hard to ensure you have an enjoyable outing, so make sure you give it the ultimate protection by running AMSOIL engineered synthetic lubricants. Check Out AMSOIL! "yes I used the search" most posts started "oil wars lol" and always ran off topic leaving the original questioneer answerless. Mobil 1 who didn't begin selling Well I just ordered 4 tubes of Amsoil Synthetic Water Resistant Lithium Complex Grease NLGI #2 GC/LB and 4 quarts of Amsoil SAE 0W-40 Formula 4-Stroke PowerSports Synthetic Motor Oil. they just wanna make you think you gotta use their oil when it's no different than mobil 1 or amsoil. Good point. Anyone running Amsoil in their rig? Have you noticed and difference in the Amsoil vs any other oil? Thanks for input. Only one I have found so far. It's time to change the transmission/transaxle oil in my '14 Ranger 570. mvi, gcr, ebw, ubl, eob, sin, uit, iqp, owa, uij, sbf, geb, djr, jgz, rdp,
