Unfortunately no. The only "good" if there is some would be if the car was started it was possibly for a test ride where the engine came up to operating temps......... especially during the winter months when you'd be running richer for a bit longer, car is taking longer to warm up and burn out all the blow-by and/or contaminants.

g911cab is infamous around these parts
If you want real piece of mind, you can get your a sample of your oil tested at a nearby lab. Owners of heavy trucks do this all the time for their fleet vehicles. They pretty much ignore manufacturers oil change intervals recommendations. They rely on the individual chemistry of each vehicle to tell them when to change the oil. Being in the heavy truck field, I've noticed that sometimes it's a sooner interval, and sometimes it's a later interval. In any event, it's a great way to monitor the health of your engine over the long term.
