'09 Subaru Forester
Oil run 9/23/12-1/5/13
46,239-51,093
Out: Synpower 5W30
In: Synpower 5W-30
Kept the Bosch D+ for a second ~5K run.
It was a dry day in the upper thirties, and I'd be reluctant to run Synpower much past 6K in this car based upon a Synpower UOA I had done from a previous ~5K run.
Since the weather was okay and the oil was ~5K, I did the change.
No telling what the weather will be like over the next month or so.

I am not sure how much went in previously. The sump size is only 3.3 qt and I would guesstimate that between 1.5-2 qt drained out. The previous oil changer wrote down the date of the service on the oil filter, and the date was March 2011. This engine is a burner/leaker, and I somehow doubt that it would've survived this long if that date was correct. Engine ran fine before and after. Perhaps a low-life technician has been changing the oil but not the filter?
The sludgey stuff drained out of the oil filter itself. I will cut it open and post pictures of it soon.
