I would use AMSOIL 0w-40 thats what i use and I dont worry about it...........

 

Yep, 0W-40(Polaris brand) that is what I used in my 2000 Magnum 500, never heard of a 10w-30 in a Polaris ATV I guess.

 

Thanks for all of the info. My Polaris manual recommends 04w 40 and I have an Amsoil dealer a mile down the road so I will go with that. But, I still don't want to drive 1 hr round trip for a filter, so I will try an auto parts store.


Thanks,

Jim

 

Mobile one makes a 0w-40.

04w-40 ? Again polaris recommends a oil they do not even sell LOL. I only see there 0w-40 and newer ps-4 which is 2w-50 or 0w-50 not really sure though. On ebay they says its a 0w-50. http://www.parkeryamaha.com/polarisa...ithawkeye.aspx

 

if i had my orgianal owners guide id proto copy it, and post it on here. and prove it.

 

I have been looking for a cheaper oil than the oem polaris oil! I would guess that 0w-40 amsoil would also work on my 04 ranger 500, 03 330 magnum and my 04 sportsma 500? the filter should be the same as well? thanks, Cosmo

 

iv check on prices for amsoil and mobile one. if you want to use amsoil and a filter its cheaper to get the kit from polaris. lest in my area amsoil is $9.99qt and a filter is round $6. mobile one round here is $8qt. i got it on sale for $6qt. filter round $6

 

Same here the $25 "Pure Polaris" kit works out cheaper then buying two quarts of Synthetic oils and a aftermarket filter up here.

 

I had the same polaris book stating 10W30 in 2001 for my Spoersman 500.
My dealer showed it to me, crossed it out, wrote 0w40 and showed me the green oil he sold that clearly said 0w40.
he too saif polarix made no 10w30.
I also found this came misprint an other service manuel-- Haynes manuels seem th be the longest running of the misprint.

as for the 10w30--I have a suspesion that the somethingw30 is the key to success.

I used the polaris 0w40, then Mobil 0W40--in one year I lost my lower ring and was smoking so bad I no bugs in the woods, and noticed the first signs of the cam lobe wearing off even thouh I did not diagnose it until a few years later when the top, middle and low ends of the rpm bands began to converge to ONE just above idle.
anyways,
somethingw30 oil may be the saving grace to get oil to the upper end.

As for cold starts, I never noticed it ever seeming slow--with the 0w40--
curious about the 10w30 in COLD climates--did it start like a cold diesel with no block heater or glowplugs?

What does 0w vs 10w really do at cold temps?
I recall in the late 80s early 90s thousands of auto mechnics refusing to use 10w40W claiming it was too thick, ruining bearings, becoming tarry sludge etc. I realize that was a crude oil base, but I still cant get it out of my mind that somethingw30 may be a good thing.

 

Here are two links about it. Motor Oil Viscosity Grades Explained in Layman's Terms

What do oil viscosity numbers mean? Learn about motor oil, synthetic and regular.

Bottom line is

Its the 0w part thats get oil to the cam quicker on cold start ups on the Polaris not the 30 or 40 part.
