...so I just had the one spanner service done by Chrysler here in Manchester, England. As I only recently bought the car; I wanted the peace of mind from having the service done by them so that I had some comeback should anything be amiss afterwards.

Anyway, all seems well however I asked what oil they'd used and they answered Mobil 1 0W 40 which is the right one, I believe. But he then said they'd left a new bottle of oil in my car - great I thougfht but it's not the Mobil 1, it's Penzoil (see attached pic)...

The questions I have are... is this oil any good? ... and is it possible they didn;t use Mobil 1 and used this cheaper stuff
