Subject: [TR] Regarding oil . . .
On the subject of oil, does anyone know anything about the removal of zinc from
modern motor oil? It's being done to protect catalytic converters. There's an
additive product that is supposed to compensate for this. Supposedly, the zinc
in the oil protects flat tappets (as old British cars have). Or you can use a
premium diesel grade motor oil which still has the zinc in it.
