Me happy cave man camper !!!
Me throw no rocks at innocents, me actually have used "additive" called ZDDP Booster which contains high quality (high vapor temperature) ZDDP concentrate cut with a known good group III based synthetic base oil.
Me used it according to mix recommendations, to achieve a certain PPM level as requested by Web Cam through research done by their distributor (Lancer) in order to give happy 500 mile break in period to hot assed new Stage II cam.
Me know what is in it, why it should work and what it does for me.
Me might throw a bone or two at people who use what they know not what it is for reasons they can't explain -- me give Bill awards out only as needed.
ugh ....
