Mobil knows more about when to start using synthetic than I do. As for new engines. A lot of people don't this but Fords new 6.7 couldn't even be made 20 years ago. The block material couldn't be machined on a production basis. It's too hard for the cutting tools that existed the. I've been in the machine shop business for 50 years. The new machines and tools are just unbelievable. Million dollar machines that check their own work, change their own tools and work lights out. You start them cut the lights out and go home. If there is a problem they call you tell you what the problem is so you can go fix it.
