My favorite brand that seems to work best is........FRESH OIL.
Everbody gets their panties in a bunch over what brand is better than the next, 25w40 vs straight 40, and so on.
you can have brad penn, amsoil, royal purple, or whatever you spend 10 bucks a quart on, and if you dont change it often, its as good as junk once it get contaminated with fuel, carbon, moisture, etc.
My advice is use a good name brand 20w50 and use a wix filter, change it often, and keep tune up in top running order. The engines will live a long time. Your 4.3 will be fine with some castrol or pennzoil from wally world.
Big rig engines go a million plus miles, mostly using fleet oils. Diesels or not, bearings are bearings, lubrication is lubrication. Key is maintance intervals.

All the other claims are snake oil. A good brand name oil changed at regular intervals is the key.
