Far as I'm concerned, I will always use OEM Kubota filters on my tractors. One, they don't cost much more, maybe a paltry buck or two per filter and two, Kubota engineers know better than I do what works and what don't. Besides I order up what I want and they get delivered to the farm so I don't even have to visit the dealer to get them and no delivery charges ever. The head parts guy has a farm around the corner from me so he drops my stuff on his way home. Filters, lubricants and grease are things I don't cheap out on, ever.
