UOA by Oil Analyzers Inc. for my 2004 Forester XT

Driving conditions: Oil in use January - August 2012. This is my first full uoa after installing the AP which explains the slight increase (?) in fuel. Previously noted fuel levels were estimates, and this one was done by Gas Chromatography. Not sure why they tested fuel differently this time. Maybe they suspected more fuel.

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. 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 make: Subaru
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

Overall severity of report = 0 Normal

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. Now running Motul 300V 0W-40.
