Just wondering if there was a reason for no one mentioning the quality of or about any problems with Valvoline Premium Blue. Thats what I've always run and am under the impression that its is CI-4 rated now(though I would still check the bottle). I also thought that it is what has been put in at the factory for quite some time. But I could be way off. 
Just Curious,
Mike

Oh-oh. So, I tow it to another place that has more capacity, tell them the sequence of events and they say, "have you been using Pennzoil in this vehicle?" Crap. They give me a couple of options and say the can fix it, but I'd be better off at XYZ shop. So, off it goes to that shop. Same thing:
"Have you been using Pennzoil?"
" Yep, why does everyone ask me that?"
"Pennzoil uses a parrafin base that builds up over time."
Now, I'm not an engineer or anything, and I know oil parrafin isn't wax like candle parrafin, but when 3 different shops and 5 or 6 techs ask/say the same exact thing, I have to give it some credibility.
At the final shop, they had to lift the engine, remove the oil pan (I'm still hoping it was just a bad pressure sensor, or maybe pump) to resolve the problem. Once the pan came off, they found a SOLID 1 1/2" of crap in the bottom of the pan. It covered the drain hole, so no oil could come out and was caked on the pump, too, though they said they thought it was still pumping oil and the engine should be OK (it was). They replaced the pump while it was exposed. To get the crap out of the pan, they had to use a chisel and hammer and chip away at it. I was there and saw the process - that stuff was rock solid.
I don't know - maybe that's the same with all oils, but for me, I'll never use Pennzoil again.

I have taken my truck to the dealer the first two oil changes. I stood right in the bay and watched the guy do it and put in the Mopar oil and my own Cummins bought Fleetguard Stratopore Filter. But, I am changing my own tomorrow (today) and im going to try the Shell Rotella T. I haven't heard anything bad about it yet. Wish me luck. Walmart had it and as I went back and forth about which one to go with before I even read this thread........I saw the Rotella and decided that was the one. I am sure the Delo and Pennzoil etc. etc. are all fine.....especially with a regular oil and filter change. I am going every 5000.

I remember seeing this problem in a haliburton Ford f250 in 84. There was sludge under the intake ontop of the lifters. That was a oil field work truck with texaco and god knows what else run in it. I dont know what could cause this but i found this.
