Low TBN though so I won't be pushing it too far. Although someone here did a 7,500 mile run in an STI (and without a TBN reading).
Do post the UOA when you can get it - I'm interested. At $9+ a quart, it better be good...

But, surprise, surprise, the problem is not fixed
. The CEL came on again this evening while idling at a stoplight. I haven't pulled the codes yet, but I'd be shocked if it wasn't more misfires. Needless to say, I'll be calling the dealer tomorrow...
Damn sorry to hear it is isn't fixed yet.
I would not pay for any additional work until the dealership has fixed the problem and kept the car for at least 2-3 days beyond that without the CEL coming back on.
