Michael,
As you are probably aware this subject was beaten to death on the British C=
ar Forum. The conclusion I came to at the time was that thinner, fully synt=
hetic oil was the best way to go. However there was still some ambiguity re=
garding whether to look for a fully synthetic that had the 1200 ZDDP or whe=
ther to ignore that. Fully synthetic oil with high ZDDP is hard to find and=
reduces the choice. I think I came across part of this chap's report when =
I was doing my research. This is a great report and seems to nail the ZDDP =
myth once and for all. I haven't read the whole report as yet but I notice =
that all the best performing oils are fully synthetic, which I guess is no =
