I have a very peculiar problem happening to my bobcat 225.

twice, I have run it for about 10-12 hours of total use, and it has gone through 1 full qt of oil each time. Here is the odd part, there is NO blue smoke, or smoke of any kind, and there is no puddle around/in/on the welder.

I have never seen anything like this. I mean, I figure an engine could consume a small amount of oil without noticing it but 1 qt in about 10 hours?

Its an onan p216 Really confused on this one....
