Synthetic oil question

[Wildride47]

Just a quick question on a well worked subject. I'm just about to turn 9K on my '12 and am beginning to think about the second oil change. I have spent the evening reading a lot of oil threads and there are mixed answers here about when to switch from Dino to synthetic. For those of you that did make the switch, at what milage did you change and is it possible changing at 10K my engine is not broken in enough yet to make the swap.

You should be fine.

Not to hijack your thread. But at what mileage is it safe to run Synthetic Oil in the truck. I am due for my first 5,000 Mile change and was kind of planning to swap then. Should I ?

I really don't think there is a need to wait IMHO. If it were my truck I would not hesitate to do it at 5k.

My stealership did my first change for free so I didn't consider it at that point. i've read these diesels like to take their time breaking in compared to their gas brothers. i'm just unsure at what point the cylinders are sealing properly and the bearings are nested.

Like I previously mentioned, I don't see why you wouldn't be able to do it now. And even if there were negative effects, they wouldn't even be noticable. No reason not to do it now. IMHO, people way overthink these motors and baby them. I understand wanting to be careful with a 50k-60k truck but these are HD trucks for a reason and what type of oil you use won't phase them.

Some vehicles come new from the factory with synthetic. In the old days or with rebuilds the tolerances aren't as exact as they are now days from the factory and not a concern. I started using semi synthetic Shell T-5 at 3,500 miles and when I reach 10,000 it's full synthetic Shell T-6. I haven't heard anyone with a 6.7 using oil before the first oil change.

I see no reason to wait. Modern engines no longer require a long break in period. Why do you want to run synthetic? Do you plan on putting enough miles on your truck to wear the engine out if you use dino oil or do you plan on using synthetic in order to extend your drain intervals?

I have a question for you guys. If I switch to synthetic can I go back to dino oil?

Before you take delivery. Ford dynos every truck, and the engine is broken in at that point.

Yes.

My truck will be getting a full-syn oil change at 500 miles just to get the initial oil out of there and remain synthetic from here on out.
