Yep, if it really annoys, then do what previous posters suggested and go full synthetic. The Ram crowd found Redline in 5W-30 was Hemi honey...there’s plenty of research and discussion over on ramforums.com under the 4G Engine & Performance section (see the “synthetic oil” thread.
I'm using QSUD 5W-30 in my 6.2 and it sounds fine...I got great results from this stuff in my Ram and Blackstone Labs even said I could go to a 11.5K OIC. I imagine my first UOA from the Ford will be similar; I’ll know for sure in about 7K miles.

Im runnings Fords full synthetic oil... I just don’t want them to put any blame on me if I start getting my oil change else where . Let’s see what they say on Monday.

I checked my remote oil filter bolts, (2) 1/2" and (2) 10mm, and all were as tight as could be. Still haven't noticed the sound since around the time I last posted here about it. In fact, I'm feeling good enough about it that I may or may not have installed an AFE intake and SCT BDX tuner.

I have an appointment (again ) with my dealership on Monday ... they want to open the valve covers to check rockers and cut open oil filter to look for metal shavings (not the microscopic ones)... but after he told me this he stated it’s a normal engine noise characteristic.... so why open up the valve covers ?

they run $1500-$1700 installed and I did test drive one but I feel the 6.2 is quicker and lighter up front

Nice, I might have to DIY a set one of these days, along with Raptor wheel.
Looking at the numbers and after doing some mods, I wonder if an uncorked and tuned 6.2 wouldn't be as fun or even more so than a stock 7.3. Though I think they are getting +80 HP / 55 FT/LB at the crank w/o any accessories on it w/ cam, mild porting, and intake manifold. Not THAT impressive to the wheels and probably not money that I would invest on a big work truck however.

Thanks ... yes it’s a stx w/ FX4 but does have the large center screen with apple car play , sat radio, Ford pass...remote start. I guess I’m just missing the power seat and power folding mirrors ... fog lamps. the leather gives it a upgraded feel and smells awesome.

I have owned many Fords since 95 and have 2 now a 6.7 and 6.2 F350’s and I never have had any problems so to speak other than normal maintenance stuff as they got older. Now I use the hell out of them for what they are intended and built for. Don’t know if that makes a difference but knock on wood it stays that way. Kinda like the 3.5 Ecoboost you here tons of crap on it have had 4 since 2010 not one single problem out of none. On my 3rd 6.7 since Ford came out with it and no problems other than my 19 it had the electric fan went bad. This is my first 6.2 and so far so good haven’t had it long but got 2000 on it and good so far.
