Thanks for posting.
Fantastic results! My local PepBoys used to carry Formula Shell as their house brand (Proline) and i wish they still did (they changed to WPP).
The Shell sheared a bit, as it starts out at 10.7 @ 100*C, but considering your city driving style and the amount of miles, i'm not sure that many much more expensive oils would have done any better.
With results like this, i'd stick with the Shell if you can get it on the cheap.
