This is my first car UOA (I posted one for my scooter late last year). Oil is M1 5W30, ST 3593A filter, K&N panel air filter. It was in service for 4 1/2 months. Mileage at change was 51,733mi.
A few short trips, about 2500 highway miles, and used in town a few mornings for my paper delivery route on cold mornings (normally use my scooter). No oil added over interval, consumed maybe 0.2 qt, no other additives. I was happy with the result, and refilled with my remaining 4.2qt of M1 5W30.
I'll admit I was getting a little antsy about a week before I decided to change it. This will put me changing the oil at the same time I do the 60k mi service for the timing belt change.
