<VV> ZDDP in Accel Oil

[Mark Durham]

Ken, if Richard is watching, he may answer the question. Barring that,
here is the link to his well written article on oil, lubrication
properties, ZDDP, petroleum based oil versus synthetics, .

Its more than just which oil has enough ZDDP.
He gives you enough information for you to decide which oil you should
use in your engine.

The 16 oz container says to add it all to engine when changing oil then run for 1000 miles and change oil again presumably without adding more ZDDP.  I need a good answer as to what is enough of this stuff.  There's been a lot of talk abot the ZDDP, but not to the amounts needed that I've seen.  Thanks , Ken Clark
