I took my car to the Ford Dealership today to get it serviced. I told them I wanted Mobile 1 15W-30 put in and to also change the transmission fluid to Mobile 1. I had no sooner got back to work when I got a phone call from my service manager. He told me that putting anything else other than Motorcraft products in my car voided my warranty. I had never read this before. Is there any truth behind this? If my engine just blows up, and they want to find a reason to blame it on me, can they tell Mobile 1 from Motorcraft in the engine?
Thanks
