Just got my UOA back from Blackstone for a 10,127 mi run on Schaeffer's 5w-40. Stock filtration/Mann filters. Fair amount of idling, which is cause for fuel dilution. Zero makeup oil was added.

Matt: VW engines don't get much better than this. The universal averages column shows typical wear from this type of engine after 8200 miles on the oil. You are running your oil longer than that, and the wear looks better. The TBN reads 5.6 so you've still got active additive remaining in the oil. We did find a bit of fuel dilution, which is common in engines that see a lot of city driving and/or idling. We don't consider it a problem at this level and will look for it to improve next time. (Taking the engine out on the highway before sampling should help) Check back.

Put it in Labor Day weekend, took it out Sat. Dec 2.

Forgot to mention that the car, upon oil change, had 110k on the clock.
