There are now 1,000,000,000,000 threads about oil that all answer these types of questions but I will answer it. You are risking stiction in any season if you use dino oil. non-sythetic oil creates varnish in the injectors thats what creates stiction.

I don't believe that statement to be 100% correct. The stiction issue, atleast in my opinion is caused by certain additive packages not able to withstand the HPOP.
Even though lube is speced CJ-4 from one company to the other there are differences, sometimes major differences, in the additive packages.

In my own 6.0 experience, I've been driving one since early '04, I have never experienced "stiction". My current '07 had three OCI's of syn 5w-40, other than that its always had dino, same as my '04. I have NEVER used an oil additive of any kind either.

I am always amazed at everyone on the syn bandwagon, feeling that its "needed". With a Racor filter and 3 1/2 gallons of 10w-30 I can do an oil change for less that 50 bucks, and change it out at 7,500 mi. intervals, with excellent UOA's.

I ran T5 my last change and sticktion developed. Added archoil to it and ran it about 1,000 miles and all sticktion stopped. Changed back to T6 on Saturday with another treatment of archoil. The engine rolls over noticably quicker with the T6 too.

Wow 7,500 mi. on dino oil. That's pretty gutsy I'd be scared to run that long. I have pushed about 4k but did not fell right about it. I would hate to have to buy another engine. But you must have one he** of a truck mine is a finicky bit** and would probably have me walking for less.

I contemplated the t5 at walmart today...but came home with t6 again. I like how the truck is running with the synthetic so Im just leaving it alone.

5k is the reccomended change interval for dino oil? is that gutsy? there is no recomended extended change interval for synthetic, so testing is needed to extend the interval.

Where do you get archoil and how much do you add.. what does it cost?
