Why not use Redline Oil as an additive? Their tech told me that the 10w30 and 10w40 Redline has:
Moly: 950
Zinc: 1400
Phosphorus: 1300
More moly than Valvoline Synpower Oil Treatment and roughly 85% the zinc and phosphorus of the Synpower Oil Treatment
Price should not be an issue as half a quart of Redline is $4 and a bottle of the Synpower (15oz) is $4. Mixed with 4.5 qts basic dino you would get average 95 ppm moly (a hefty dose) and boost the zinc and phosphorus by about 40 and 30 ppm. An added benefit is the ester base oil of Redline which should give you a "Start Up" advantage as it clings to metal. The esters may also help clean the engine.
