Ignorance? Ya call me ignorant on the net cause I don't buy in to all the BS... I use what I know is good... Go put your 2 cents in somewhere else cause you haven't contributed anything to this thread... UOA are very beneficial yes... I don't do any reading into penzoil because I don't care for it? Yes.. Does that make me ignorant? Whatever you think big guy... I've tried a few different oils but penzoil and Quaker state will never be one of them...

When I had my diesel I'd get an analysis from Blackstone every other oil change. That was after changing the oil every 7K miles and over 200k miles on the truck. All reports where always good and they wanted me to change the oil at 10k miles and send in a sample. Never made it b/c I trade the truck in with 225K miles on it. I was skeptical letting it go that long on a high mileage truck with only dino oil.

Any differences to consider running 5w-20 on a DD non SC seeing alot lighter duty cycles over say a 5w-30 or even a 0w40?

Ive seen the arguments for running 0w40 (which is what i ran in my old Twin turbo 350Z making 450hp) because it protects better at high and low temps and had great results confirmed by blackstone.

Trying to educate myself on the difference here with being a truck/v8 and all that.

This is my first gas truck (had 7.3 diesel before this)
