Actually, Quaker State and Pennzoil no longer use any Pennsylvania crude.
All comes from points south now. Actually, they are both owned by Shell now,
so it will be interesting to see what comes of that.
Teflon, made by Dupont, is not recommended by them to be used inside
engines. To be honest, from what I have seen thru work, it is all pretty
well snake oil. Lucas makes some petroleum based products which seem to work
ok, but all the rest I have no faith in at all. If you want better oil, use
synthetic.
