I’ve never bought a filter or oil or belt online. I don’t see how I’m ruining the economy by buying at the Napa store or the dealer across the road. Has anyone ruined anything with the right but different brand filter? That issue seems on the same page as drilling a hole in the ROPS. The closest thing to an issue I’ve had is someone put an engine oil filter on the HST filter place in my F series Kubota. It severally limited the transmission power. after I got it fixed there seems to be no damage. My family has used pretty much solely Napa parts since my grandpa owned the place 30 years ago. We could afford an engine rebuild that’s never happened with all the money saved.
