Thanks. That's what I'm using. Just did the break-in service a few days ago. Alba Racing recommends it along with Polaris Demand Drive fluid, but they don't like Polaris engine oil. They use, recommend and have seasons of desert racing success with Maxima SynBlend 4 10W-40. I used that in a bike I used to have and my son sold a lot of it when he owned a bike shop in Roseville, CA, so that's what I'm going to use in mine. Amsoil seems to be at the top of the oil heap, but I think doing shorter oil change intervals than Polaris recommends eliminates the need for a full synthetic.
Getting back to the bearing issue...I plan to do an occasional oil analysis on engine oil and wonder if it would be a good idea doing an occasional analysis on the the trans/diff oil for an early warning for impending bearing failure? Might be worth a call to Blackstone Labs for their opinion.
In keeping with the thread subject, my UTV Inc. fire extinguisher quick release bracket and extinguisher just shipped. Arrives tomorrow.
