Youre not the only odd one here, bumcover, I also use T6 in my '13 V6 fronty & have gotten excellent UOA's from Blackstone. It runs nice & quiet, no noisy lifters or timing chain rattle, & most importantly it helps it run cooler in these HOT Texas summers. Speaking of timing chains, Ive found a way to help keep the them from rattling so much on cold start ups. Heres what I do; I put the key in the ignition & turn it to ON but DONT start it. I wait till I hear a slight 'clunk' from the engine bay THEN I start the truck. After the engine has started I hold the key in the 'start' position for just a split second longer then I let it go. Doing this method I hardly ever hear the timing chains rattle if at all. And, using the T6, if I don't do any of that they only rattle for maybe a second or two at most then stop rattling completely.
Now, what that slight 'clunk' is after I leave the key in the ON position for a couple of seconds before starting, I'm not sure. Maybe one of the oil solenoids to the chains opening?? All I do know is that running the T6 in my truck it runs smoother & quieter than any other oil ive used.
