UOA by Oil Analyzers Inc. Previous uoa here.
Driving conditions: Oil in use January - August 2012. This is my first full uoa after installing a Cobb Accessport and I am running the standard "Off The Shelf" tune which explains the increase (?) in fuel. Previously noted fuel levels were estimates, and this one was done by GC. Estimated hp/tq on the Accessport for my year Forester XT is 270/285.
7 mile daily commute each way; spirited driving with a few redlines here and there on days where I have a 20 minute drive. Longer trips on weekends as well as driving on the beach. I ran the oil for about another 1,000 miles after this uoa and the factory recommended interval is 3,750 miles. 1/2 quart make-up oil added at 1,860 miles into oci and one quart at 3,220 miles into oci (after trip to SC that included more enthusiastic driving
).
Lab comments: Data indicates no abnormal findings. Resample at normal interval

Equipment model: 2.5L Turbo
Oil use interval: 5140 miles
Oil type & Grade: Mobil1 0W-40
Make-up oil added: 1.5 Quarts
Miles on unit: 122,140
Air filter: Amsoil Ea panel filter
Oil filter: OEM Honeywell

If I didn't get Motul for free with my Subaru cc rewards, I would probably stick with this oil. Actually, probably not since I change my mind once a week.
