I have a 2012 Toro ZTR with a Kawasaki FR691V 23 HP. engine. I have had an oil burning issue for about 4 of the 5 yrs. I've owned it. Only smoke I see is on first starting up. Especially after an extended sit. Once I even fouled a plug from oil. Of course dealer said that they never heard of oil use but they'll be glad to look into it if I bring it in. Which I haven't. I never have to add a lot at one time but, being aware that it uses I keep a watch on it. Has anyone had this same issue?
