Nice. That is some low klm's for a 2005.

Any dust storms up there? Air filter issues?

I really wouldn't worry too much about the "dust" or whatever small particles are being detected. If they are not causing excessive wear (which they are not) then just keep on doing what you are doing. The M1 0w40 looks like a great fit for the vehicle so I would keep using it.

PS: I think it is almost impossible, unless you install a bypass filter, to remove particles that size from circulation. No harm.

Well, TBN isn't affected by the low mileage, that's for sure. Healthy 12+!!!

No nothing like that up here. I'm at a bit of a loss to what it could be as this has been the main 'issue' (not that im too concerned) with my UOAs. Various different brands of paper filters have been used. I'll be replacing the original plugs on it soon which means replacing the paper intake gasket with a aluminium one so hopefully that might be a source of entry.
