The are many many automotive oil filters though. I use a Fram CPH6607 because a store near by sells them along with Amsoil 0w-40.

Walmart Super Tech filters are made better. I use Napa or Purlator, very good quality, in the 5-8 dollar range, Mobil 1 also makes a good filter,and there are several others, filtration, bypass capability and pressure,and construction are very important in a filter,good oil and a bad filter can leave you with a siezed engine as surely as a good filter and bad oil.

On the website they show they use three of the Twin Cities oil companies as there suppliers(Gopher State Oil, Hallman Oil,and Jennison Rollins Oil Company. LUBE-TECH started operations in1993) Plus they are partners with the Swiss base Motorex oil,which is what we sold the most of to KTM riders! From 1988 to 1994 don't really know who the supplier of our 2-stroke oil was(could still have been Lube-Tech) as Polaris didn't have a four stoke at that time,plus up until 1995 we used a NASTY graphite based gear case oil for all transmissions. Would actually stain you hands so bad you couldn't hardly scrub it off! OPT

After the warranty use what ever you prefer then.
