Nice link Martin, very interesting.

I got to spend some time in Esso's Higher Olifin's plant, where they made the base stock for Mobil 1, and the rest of the Lube Plant's lubricants. It was fun working at one of the few completely integrated refineries in the world, and the oldest.

I disagree on the ZDDP based on evidence I have seen and monitored. Part of the issue of wear on cam followers is the quality of reproduction parts rather than any issue relating to the oils in use in my opinion.

I hadnt heard rhat, the B series engine flat tappets have been a source of concern personally I choose to use an oil with enough ZDDP content so that whatever the details may be, I wont have a problem.
