Yup, if you have oil change receipts, they'll likely not bother sending off the oil unless they have reason to suspect that you are lying/the records are forged.Devils Advocate: Couldn’t the dealer simply ask for the oil change records to verify oil changes were done timely and with properly spec’d oil/filter? I’m no Rocket Surgeon but would seem way more straight forward and definitive.
* This is predicated on the notion that oil damaged the engine and the dealer suspected such. Which I don’t think either would happen. Again, devils advocate.
This is one "plus" of having the vehicle serviced at the dealer, even if you provide the fluids, as they'll have those records readily available.
