I use Castroil 5W-30 in this truck. I suspect the usual things like Valve guide seals.
I added some stuff called Lucas Oil Stabilizer, but then did a search on this forum to find out that this stuff has caused engine failures, but the one oil change that I did use it, it did seem to cut down on the consumption. But I am a little leary about continuing to use it because of the bad reviews.
Has anyone had similar experiences? Would synthetic be better? I know going to a little thicker oil (Maybe 10W-40) would probably help, but I'd like a little guidance.
Throw me a rope here, you guys are the best.

1.) Replace your PCV valve.
2.) Search for PCV catchcan in this forum. I wrote an article on it. Works awesome.
3.) Add only 5.0quarts when you change the filter and the oil, DO NOT FILL TO THE TOP OF THE DIPSTICK AND GO OVER 5.0 QUARTS. The engine might be just trying to get the excessive oil out of the system.
