That's what I'm shooting for... long term. I got a buddy who thinks I'm nuts that just traded his 2017 F350 6.2 for a 2019 F350 6.7 but this guy goes through vehicles like he goes through underwear...often. I told him about the new 2017+s having a new design in the CCV system that has filters that clog up. He laughed and said that why he has the warranty and that he won't have the truck long enough. But yet he's the same guy who changes his 2017 F550 6.7 flatbed's oil every 1500 miles or so. It does sit a lot as he's in the city where I work and tows for us when we need hooks for the job. I'll found out how many miles on the flatbed because I know it's not a lot and how many times he's changed the oil. I'm going the distance with my truck. I want to give it the best chance to last. Just my POV...

Ford does not fill the 6.7l with synthetic oil at the factory. Check the Valvoline UOA thread, I had my factory oil tested and it came back as 10w30. There is no synthetic diesel oil available in 10w30.

Wow! This is getting involved! Amsoil NOT being on Ford's approved list worries me. I was a believer of their oil and used for many years on my 2008 6.4.
Where can I find a list of Ford's "approved manufacturer's brands of oil"?

I've been running Motorcraft 15W-40 for a few years with no problems. I tow a 17K pound 5th wheel in hot conditions and living in Louisiana no real cold weather to contend with. Change oil and filter every 5K miles and air and fuel filters at 15 to 20 K miles. Air and fuel filters are expensive at the dealers. Most oil is packaged at blending plants and blended and packaged according to the customer's specs. Can't believe how many guys run full synthetic oil and then put the cheapest fuel they can buy!

That is the other thing that surprised me. I have been using 15W-40 in my 2008, 6.4 since new. I'm sure that that is what ford recommended. Although, I don't get my 6.7 for a couple of weeks, it looks like 5W-40 is recommended for where I live (Canada) based on the Owner's manual that was posted earlier. I will be sure to ask about it at the dealership when I pick it up.

The 2016 Diesel supplement says the same thing.

If you're in the gReat White North, I'd at least consider looking into 5w40 for better flow when starting at cold temps.

If the page formatting didn't change, the list is six items longer than May 2019 but that's all I know. My oil changes are simple, I use Rotella T6 so I think the only time I look at this is when it gets discussed here. I've attached April/August 2018 and May/August 2019 for if you get stuck on a boring assignment today. Notepad++ can do a compare but no easy way with the way this is formatted.

The manual says not to tow for the first 1,000 miles. Its not for the engine its for the rear end gear set to brake in. I believe all ford vehicles come with full synthetic oil from the factory. Motors are so much better that you don't need to brake them in like the old days. I only use Motorcraft oils and filters for my truck. Sure it may be more expensive but you dont have to research and spend time looking up if it's ok to use. I spent $8,000 just for the diesel so I see no reason to skimp on parts. You used to be able to find the oil % on Sync but Ford discontinued that (sad) So I just wait for the truck to tell me when to change the oil. I buy my fuel at a place that sells lots of diesel so I know that the fuel is fresh. other than that just drive it and don't worry. it will wreck your driving experience owning the new modern diesel truck.You will love the power and how nice these trucks tow.

My 15 doesn't have all that cool stuff. (sad) Low tire Ford says guess which one. I wish when they had a better idea they would stick with it.
