Oil Sample question

Looking at purchasing a truck from a dealer and they have completed a PM service on the truck prior to putting it out on the lot. The truck ran for about an hour today and I took a oil sample to send out.

Is this pretty much a waist of time/money or is it still good practice to do this?

 

I drove it from the dealer to a independent mechanic shop which was around 10 miles and took the sample at that location. How many miles are your test drives generally?

 

I've seen your response to another thread a few months back concerning the Dyno and ECM Dump, I understand these are done at the buyers expense but are you having this done at the dealer you are buying the truck at?

 

Ya, that's the thing with the dealer when they PM every truck to get it up to their "Show Floor" condition. The PM is done before the truck is put up for sale so you cant get the oil sample you would ideally want.
