The Mobil AV-1 story

Are organic disperants totally ashless? Can they scavenge large amounts of lead compounds from the ring area?

Yep, but they are not cheap.

You are 100% correct in that Mobil AV-1 could have been merely tweaked to achieve a very high level of performance in lead diispersion capabilities. It was in fact accomplished in the lab; however, the cost of re-cirtification of the oil with FAA would have taken much time/money and not cost justified.. And Mobil did test the oil very extensively but one cannot test with every variant that exists and it would have been difficult to imagine engines with as much blow-by as some of the problem Continentaqls and still pass annual inspection! But they did and the rest is history..
