0W40 synthetic.
I am usually an Amsoil booster but............ I had to stop running it in my 01 Cat. The 0W-40 says that it's ok for wet clutch applications but after a few oil changes with it I was starting to notice gear slippage and blow by coming out the exhaust. I have now gone back to the factory Cat oil. It seems to have a little more "traction" in it. (lol, not usually a desireable oil property) Amsoil = too good for my machine.
Amsoil is based in Superior Wisconsin, and to the best of my knowledge is not connected to Amway in any way. http://www.amsoil.com/storefront/aff.aspxAmsoil only has one brand of 0W40 for ATVs
I allways run Valvoline 10-40 atv in my 03 Foreman (4000mi.) never any clutch slippage or blow by. The dealer warned me not to run fully synthetic. You may be able to run synthetic in a Sportsman because they're no wet clutches. A Rubicon has multiple wet clutches and would use extreme caution with synthetic oils.
I run Arctic Cat 0W40 synthetic in my kitty because it has wet clutches and the oil is designed for this application. Maybe your dealer is thinking specifically about hondas. I run this oil because Arctic Cat recommends it after break in.
I think arctic cat atv's have belt drive CVT transmissions NO WET CLUTCHES!
THINK AGAIN!
what model??
I was looking at a Rubicon....
