When I bought my 2002 F-150, in 2002 I became friendly with the service manager and he basically said they really just check to see if the oil and filter were changed in a timely manner. They will pull the valve covers and oil pan to see if there is sludge indicating lack of oil changes. He told me about vehicles, especially lease vehicles, coming in with blown engines and the factory fill and oil filter still on. Needless to say the customer had to pay for the repair. Even though my truck called for 5W-20 he said I could use 15W-40 and as long as there was no sludge build up I would be covered for engine problems. Of course each dealership can vary. Some may be sticklers as to being "by the book" for oil requirements.
