Hey guys, I have an '01 763 with the Kubota motor. I picked it up Thursday. I was told by the tech at Bobcat NH that this machine should NOT run Bio diesel. In fact he handed me two decals to place on the machine indicating anything over B5 could cause harm to the engine. We've always run B5 and B20 with no ill effects in our rovers and I'm wondering what the deal is with the Kubota motor. The machine has all new filters so I'm not too worried about dislodging sediment from the filters. Anyone here have issues running Bio? Thanks, RJ
