dino oil and ZDDP additives ? anybody

I always recommend a additive! I never trust the oil company's. That's how we got into this mess. The highest mileage engine I put together. Is a performer cam'd (flat tappet) 468 in a dualy. It see's regular horse towing duty. Going on 120,000. Every oil change is Rotella with red line additive. My two cents, from my experience. To date every motor I have built, has been because of a flat lobe. The owners didn't know they had to add any ZDDP! Again, this is just from my experience.
