Thanks To Pitzel, I got a UOA from Finning Cat (formerly Kramer Cat), they were cheap, fast and local. The results look fine to me for the questions I had that were the purpose of this thread, but I will post the UOA in the UOA subforum. thanks again for all the suggestions here. I have kept track of the miles at time of oil change this time and will use that and the oil life indicator to decide when to change oil next.

Unless the oil smells like petrol, I can't think of a reason why possibly you wouldn't be able to extend. I think Kramer equipment up by Buck's Auto Parts/IPSCO has UOA services. Not sure of the terms.
