I'm a very analytical type person who always wants to know why or how something happens when a problem presents itself. Never had an oil analysis done, but I know it's time to have oil changed when it's black, thin, and my truck runs like crap. It happened everytime and was followed there after with foaming. When I used either Valvoline or Castrol, it never happened.
I've looked into this time and time again and it seems that the truck has a mine of it's own...

Yes same here, don't mean to offend. Color means very little. If you're foaming, the oil is thinned out, and truck is running like crap, it get a little more analytical and have an OA done to see what the problem is. It might not be the oil that's the problem.

My truck gets nothing less than 15w40, it's what it came from the factory with and it's what keeps it happy.
Given the advice so far, I'm considering an Oil Analysis to see what could be going on. But what gets me is that only those two oils make it to 5K and the rest are ripped to shreads in no time....
Btw, how much is an oil analysis anyhow?

May I ask what oil filter you are running, and also, are there any loose connections from your 6637 to your turbo??
Good Luck with this, it will be interesting to see what comes of this.

schaeffers 9000 is ful synthetic 5W-40, you can get 5 gallons for about $100, but if you are only changing every 5K or 10K its actually cheaper to run it. i loveit and would never go back to anything else.

Schaeffers oil analysis is cheap I think around $10 or so. I have never used them. I use Blackstone. They are a little more expensive, depending on what you get, as much as $24, if I recall correctly. I started doing it with Blackstone so I keep going back to them.

Is there another filter you guys would suggest?
Found my 6637 filter loose this morning since I just put on a new one, but got that fixed. All intercooler boots are also tight and holding.
