Looks like this thread could use a little help....
Oil is extremely important in the 6.0. Ford made a huge mistake by using dino oil in these engines. The oil does not only lubricate and cool the engine but it is also used to power the injectors and control the turbo. The oil goes through a high pressure pump that can create up to 4000psi at WOT to push fuel through the injectors. Needless to say if you want your turbo and injectors to last you should defiantly be running a Full Synthetic oil in these engines. Most guys on here run Shell Rotella T6 5W-40. It is perfect for year round use and gives the best lubrication possible. Change it every 5,000 miles and you should be good to go. And remember to always use a Motorcraft or Racor filter ONLY!

I used to run all Rotella t5 conventional 15w-40. I just did studs and gasket and new injectors so while I had it apart I sucked all the oil out of the oil cooler reservoir and drained the oil. Added new filters and Rotella T6 5w-40 and will continue to run that for the life of the truck. TSC has it on sale for $19.99/gal here probably close to the same where you are.

UOA reports have shown the T6 good to 7k miles or more. I run Amsoil 5w40 and use 7k as my OCI based on UOA. It may be possible to push the OCI out further but I would only do so based on UOA verifying it to be ok on your truck with that particular oil.

Ran Amsoil 15w-40 and the truck loved it, running t5 now and it's a bit louder (the shop that did my hedstuds put it in, not my doing) but will be trying t6 once this is done. My local Napa has it for $20 per gallon so it's way cheaper than amsoil in the long run.

T5 also comes in a 10w40 blend and Triple protection aka T also comes in 10w-30.

Why do you change the filter every 10K and not at 5K with the oil?

Well for what it is worth I use Rotella t6 every oil change and have for the life of the truck. A long time ago I sent in samples to be analyzed. I live in central California so the climate is great and I rarely pull super heavy loads. The truck is my daily driver and I do drive aggressive from time to time with a performance tune. All that being said I went from changing at 3K miles to 5k miles then to 8k miles and the last 3 have all been at 10k miles. All 3 of the last changes where sent to Blackstone for testing and all 3 have come back saying I could have probably went longer. I always use Motorcraft filters and Shell Rotella T6 oil.
I know many people will say that 10K is too long but like I said, for my use the lab suggests I could go further. Oh and the truck just turned over 100,000 miles and still running like a champ. Take i for what its worth but I suggest you send a sample in after 5k miles and see what they say. It was more than worth it to me.

Agree 100%. I've been running full synthetic since 15k miles (wanted to make sure everything seated like it should), and we just pulled my heads last month. That was 145k miles later. My friend doing the work was anti-synthetic oil ever since I've known him, but he commented that I "may have just made him a believer in synthetic oil."
FWIW, I didn't know my oil cooler was clogged until recently and I was seeing EOT's in the 245-250* range every time I was on the highway. I don't know how long they were this bad (ScanGauge was purchased a few months ago), but my oil had 4,500 miles on it when I sent it in for a UOA. The results passed every test with flying colors. I don't think that would have been the same had I been running dino oil.
