Probably don't make the 0w40 anymore and the 5w50 has replaced it.

 

Save your money and get a 5 qt jug of Mobil 1 0-40 from Walmart , about half the price of Polaris oil .

 

yep, that's just the latest "new" oil from Polaris. The oil you have now is what they have used for years. Now they have a new oil. They do that ever few years. If you want you can switch to the new stuff next change...Or...as said above, just go to Wally World and get the same stuff cheaper in a different bottle.

 

hey
I figured as much but wanted to ask
Amsoil Formula 4-Cycle Powersport Oil, 0W40 is what I put in
so stay with the 0w40 and don't worry about going to 5w50
thanks

 

I found that my ATV started easer in in -0 winter weather with the 0W40.

 

It doesn't usually get all that cold down here in KY but I have no doubt that your statement is spot on, reynoldston. In all fairness, I have been considering going to a little heavier oil like Polaris is now recommending in the summer and then back to the 0w-40 in the winter months.

 

I have been using Mobil 1 0W40 and the bike is 13 years old with 7500 miles of hard off road riding and plowing snow in the winter. The only engine problems I ever had with it is oil leakage. I did try the heaver oil one season but had starting problems when the temp. got real cold. The first oil change I used Polaris oil and then a few years I ran synthetic Amsoil and now Mobil 1. I change my oil and filter once a year.

 

I have used Silkolene Pro-4 full synthetic 15w50 in my 04 since it was new - have had zero motor problems

 

hey
ok thanks for the info
will keep using what I already put in.
thanks
