My friend has two new 37 hp Bobcats. One of them started smoking blue at start up and using oil at an alarming rate. His dealer has told him to keep a record of the oil consumption. Since they are new I'm not too worried for him but is there anything he should be sure to keep record of or be sure not to void his warranty. I know most engines require a oil change at 5 hrs or so, though I'm not sure that would void a warranty. I just talked to him on the phone today and hope it's something simple. What steps would you take to make sure this was fixed in a timely manner and that the warranty stays intact besides keeping good records (it's new so there shouldn't be much to record other than oil usage). I think I would be a little sick to have this problems so early on.
