I recently viseted the dealer where i bought my 2005 500 [they dont sell polairs any more] but still have some parts 'while I was there the parts man asked if I were interested in a oil change kit (filter& oil) I said no I use castrol syntect (5-30) and afer market filter . He told me regular oil 5-30 was no good becase 5 weight oil was to heavy for polairs start up , he said it would blow out crank seals ?? Ive done this since 2nd oil change with no problem any one heard of this I tkink he's blowing me smoke but thought what you guys though..how about it OPT.

 

I hav e used 5w30 castrol syntec full synthetic since new in engine and tranny , one machine has 7000 miles, the other has 4700, no problems, it works great.

 

Wix 51358 or NAPA 1358 for the oil filter for the 500 HO

0w40w Mobil 1 for the oil can be purchased at Walmart. YOU MUST USE SYNTHETIC OIL.

Been using it since my 2001 sportsman 500.

Use this to look up the oil filter. The NAPA # is the same but remove the first digit (5)

[img]i/expressions/face-icon-small-happy.gif[/img] This question has been beat to death,BUT you probably can get by with 5-30 IF you change oil a little more frequent! BUT still tough on top ends(I've seen enough of em) 0-40 or 2-50 gives you a lot better viscosity range,plus gets to cam and rocker arms quicker on cold starts and better protection during summer heat when you need the 50 wt! Some have gotten by ok with different oil,BUT I've also seen way too many that didn't! You paid several thousand dollars on your machine,WHY go against what is best? JUST from a mechanics viewpoint!

 

0-40 Mobil 1. I use the stuff in my quads,sled, and ZTR mower. The single best readily avalable oil.

Meaning available at Wal-Marts, Farm & Fleets, Auto-Zones, etc.

 

Are you supposed to use only 0 w 40 os such because I have used 10w40n sence I got mine, Thats what the previous owner told me to use. Should I change??? mine is an 01 sportsman 400

 

10w 40w is fine in temps above 20 degrees F.
