As many of you are aware, the gov't is demanding less and less zinc and phosphorus additives in lube oils for engines and transmissions. The idea is to extend the life of cats(catylytic converters or scrubbers). That's bad new for us with older iron and particularly those with flat tappet cams. Came across this article the other day:
New antiwear and EP additive technology | Tribology & Lubrication Technology | Find Articles at BNET
Platinum Research Org. in Dallas, TX is finding that fluorinating ZDDP is increasing it's protection level, and that with a lot less phosphorus. Basically in a nutshell while the level of anti-wear additives are being restricted, someone is finding a way to keep them effective with less than was needed before. They ain't there yet, but I'm think'in it's hopeful.
Dick, do you know anything about "PRO" there in Dallas?
