Has anyone found out what weight of oil the PS-4 is? This is really bothering me. I cant believe Polaris says to use PS-4 or something equal but doesnt even tell you what weight it is. Right now I am running the PS-4 but would like to know of other options also. Been thinking of ordering a case of amsoil but not sure what weight. Also mobile 1 has a MXt4 for wet clutch applications but again is it the right stuff. Any ideas

 

I too would like to know what the PS-4 weight is. I thought polaris was kidding when they said an oil change every 10hrs., but they weren't. This oil breaks down pretty quick. I'm thinking about loading up some of Yamaha's 10-50 for the race season. Any other ideas?

 

My dealer was told when the Predator first came out, they could use the Kawi-chem 10w-40 synthetic oil. This was told because the PS4 was not out yet. So I was given this oil to do my first hr oil change. I'm ready for the next one, but I'm going to try the PS4 for this one.
