MOBILE 1 OR ROYAL PURPLE
So... I read an old thread about changing the angle drive oil. The manual says to change at 50k miles, but I was wondering what the final results were on changing sooner. I figured most of you that have changed the oil would have had enough time and miles in to give a solid review on your findings.
Also, what oil did you use...Mobile 1 or Royal Purple?

Ok, so at 2332 miles, I just changed the drive oil to MOBILE 1. There was about 1/8" of sludge and shavings on the magnet on the drain plug. The oil was also pretty dark. After changing the oil and going for a decent drive, the "chatter" from the rear of the vehicle was, IMHO, DRASTICALLY QUIETER!
I do not see how the factory oil can last 50k miles...maybe it's just a scam for polaris to sell more angle drives after they fail after the 2 year warranty. ???
I was surprised how dirty the stock oil was after only 2300 miles!

This was on the original drive. At 10k miles the dealership changed it for a new drive. One dealership thought I had a bad drive, but it was only a REALLY bad bearing. I called my dealership freaking out cuz I thought I had a bad drive. This was right before the Slingfest Cup Track Day and Panama City last October. Even though It was just a bad bearing, my dealership went ahead and changed the drive. I still have the factory oil in this one but at 10k miles on this drive. This one never made the whinning noises like the first one did. Regardless, I plan on changing the oil to Mobile 1 before Maggie Valley.
Here is how bad the bearing was....
