Dont know if this is the right spot for this....but here it goes: My father and I own a 2003 Kawasaki Prairie 360 and a 1999 Polaris Sportsman 500. I'm a strong believer in the great benefits of Fully Synthetic motor oil for all of my vehicles and I'm looking to see if there is any ATV Fully Synthetic brands out there that I can use for the ATVs?

 

Rotella T6 works well and is readily available.

 

you can use any 10w40 synthetic if you don`t have wet clutches. I run it in my kfx700.

 

does a "wet clutch" just mean an automatic? Both of the ATV's are automatics.

 

does the engine oil lub. the clutch? or is it an external belt auto.? amsoil does have a syn. oil for wet clutches too. had it in my 700xx Honda.

 

Polaris recommends full synthetic oil. 0W40 works in most temperatures.

 

Polaris only sell Full synthetic oil for ATVs.

Google "conventional oil vs Synthetic" except for price conventional loses in every way.

I switch from Polaris oil to Amsoil 0w-40 . 0w-40 only comes in full synthetic I think.

Do not get the rip off blend stuff ,that's lucky to have 20% snynthic in it for almost the same price.
