Whats the deal with Polaris's 0w-40 oil?
How much protection in high heat will this provide? A forty point span? Must have alot of polymers.... not good. I think I will stick with 5w-30 or 10w-30. I realize lighter viscocity oils flow better when its cold but do they provide a wide enough "film" thickness for protection?

Maybe I am missing something. anyone?

 

I do know it is a good oil. We had a customer who ran a Trail Boss for approx. 45 mins with no oil before it finally seized. One of our former mechanic's runs it in his '97 Chevy Blazer. I have given thought of changing to Amsoil 5w-30. However I haven't seen any problems with the Polaris brand.

Is this gentleman independantly wealthy? 5 quarts of 0W-40 is not cheap!!

I have had the same thought there Grizzjeeper.

I wonder why Polaris 0W-40 is so thick when you pour it? It does not pour as fast as Mobil 1 with a similar viscosity. So I wonder how good the Polaris oil really is for starting an engine on those sub zero days? I am using it only because I have the extended warranty. Without the warranty I would be using Mobil 1 0W-30 in the winter and 5-30 in the summer.

 

$5.49 a guart is nothing compared to some upper quality synthetics. What do you pay for a guart of Mobil 1. The cheapest I have found it is as special on 5 quart container for $17.88 which is a hell of a price for it. By the quart it is the same exact price as the Polaris. Don't get me wrong I love Mobil 1. That is the only oil that sees the inside of my Ranger and Camaro at this moment, however I may be switching to Amsoil soon. I will say he had no problems starting his vehicle in sub-zero weather and he changed his oil like every 7,000-10,000 miles and the oil looked like it had 3,000 on it. I have never done any tests on it personnally but I can only state what I have seen and so far I believe it is a excellent oil.

 

So what is the weight of the oil needed? I have not yet changed my crankcase oils and I know they are due.

 

The 0-40 Polaris synthetic oil works fine. I have run 5-30 Mobil-1 when I didn't have any Polaris on hand, but we are in the process switching everything over to Amsoil. In fact we will be running 0-30 Amsoil in the atv's, tractor, mower, vehicles, (except our new 2500HD Chevy Duramax diesel, which gets Amsoil 15W-40 synthetic, all 10 quarts.)

I have used Mobil-1 in lots of vehicles without a problem, but you won't believe the difference in the wear tests with Amsoil Series 2000 0W-30. Just about everything got switched this past month, including our two strokes which will now run Amsoil 2-cycle Racing oil @ 50:1 vs. the present Klotz and 40:1.

 

You replied to my post about oil since our dealer here has not received his shipment yet. Polaris oil is fully synthetic and I was reading in my manual that Polaris recommends that you use only oil that has an API rating &quot;SH&quot; when I went to the parts store the only Mobil One That they had on the shelf was a blend that carried that rating and they didn't stock 0W-40 viscosity. So I'm confused. I e-mail Polaris trying to get them to recommend an oil but they have been silent. I guess I'll just drive to another county and see if the dealer there keeps his shelf stocked.

 

I run the 15w50 mobil oil in my 400ex. I have nothing but good to say about that oil. What is the temp rating for the Amsol 0w40? A local shop is carrying that now. It'd be kinda nice not having to go to WalMart not all grubbed up getting oil!
