Hmmm..... I guess if my local dealer supported me, and warranty was an actual thing with BRP/CanAm..... I would think about supporting them with more than my original purchase... But as it is??? I don't support my local dealer??? More of a pusher really. They all want to be your buddy, until your ADDICTED!!! Then yer just another buck....As many different answers as their are owners....but for me, I use the OE oils and filters. Small price to pay to keep supporting local dealer. They designed it and back it for warranty.
