Well the forum was a little slow for the last week, so I thought I'd stir something up lol. No but really I've used Mobil 1, Castrol, and Motul. I was just wondering if anyone was using it. I know some peps say to use an oil high in zinc, but none of them really say how much is in there oils. Just wondering if anyone used it or not. Disclaimer I don't own a cat, nor do I hate them
