Based on a modern 4.3L internals and the metals used inside, what dino/hm blend oil is recommended based on paper? What I am asking is should I be looking for an oil higher in sodium, calcium, boron, zinc, moly, etc.? I currently use Maxlife blend which seems to hold up well for the frequent short/cold trips I do, however I have heard that large amounts of Moly can be corrosive to some engine metals such as copper, etc. Is this true? I know that there are a couple types of moly and this is referring to one or the other. I will always do 3k ocis with K&N, Mobil1, Pureone, or Carquest premium filters due to the worries of a faulty intake manifold gasket on this engine I will always stick close to 3,000 mile oil changes. Dexcool was changed out at the 30k mile marker for Peak Global lifetime. I just want to stay ahead of the game as I will never sell this truck. By the way, the truck is a 5-speed & has a K&N Gen II intake system with Magnaflow cat-back mandrel exhaust and a custom computer tune with 93+ octane for max lbs.power & mpg performance. Before anyone hates on the K&N filter, I also have a pre-wrap filter on the cone for the last 10k miles and I recently checked the filter itself which has held its cleanliness red color.
