Yes, I know where we are?
Well, thanks for the Rotella compliment. About time you came around to the Rotella way of thinking.
This coming from an Amsoil dealer. Still the same old BS as usual.
If Rotella didn't work as well as Amsoil in our vehicles maybe your post would make sense.
So, are you trying to impeach Rotella? Where is the evidence? LOL I mean real evidence. Not the thousands of Amsoil test comparison advertisements posing as scientific fact.
Polaris PS4 is just as good as Amsoil too. Maybe better.
Hey DaFish, Which Rislone product are you referring to, the hyper lube zddp suplI have used T6 in everything for years, and I'd like to think I've adequate research into it.
T6 is designed for low revving engines? .NOT. That's an unsupportable myth. It's an HDEO because it doesn't meet some of the requirements for auto engine oil. Although in truth I think it does now. Zinc is 1200ppm, and that's the api spec now so... And the rest are usually smaller hurdles.
Usually a friction modifier is adding friction. Like in a manual transmission oil where some sticky is a good thing. Add pacs containing anti-wear is a different thing. Here you'll find zinc as an anti-wear, molly as a super lubricant, various cleaning components, and etc.. Mind you that's an endlessly complex topic.
T6 5w-40 has been my choice, although it does tend to shear down in engine/transmission applications over time. Like in a bike. That's to be expected, for viscosity improvers literally get shredded in transmission applications. Use a group IV oil, change more often, or select another oil with less viscosity range.
My next change in the bike I'll likely move to T6 @ 15W-40 and forego my "one oil for everything" convenience.
For a rzr engine non-turbo I think T6 5W-40 is where it's at. For the turbo's I suggest M1 advanced in 15W-50. Either could use 1oz of rislone zinc additive per qt. And I think engine idle for at least 1 minute pre-shut down is a good thing too for a turbo.
Hopefully this helps. If you want more I've threads out there digging into this in some depth.
