Oil - You get what you pay for!
Discussion
Simon,
The Castrol testing included EI and CI mass spec work, and a catalog of the complex hydrocarbons.
I understand the Castrol esters were developed in German labs between approx. 1991 and 2000 and have been improved upon since then. There are two types of these esters, both derived from PAO olefin polymers.
It is believed these esters are responsible for the AW and FM performance of GC wihout the inclusion of triborates and molys.
With the levels of zddp and calcium, and the high viscosity PAO bases, the formulation appears to be a good one.
Just nice to know what you pay for.

Interesting thread, thank you...! My RS500 runs on 'Silkolene Pro R' I think. Good to know it's decent stuff. Perhaps I should switch from Castrol Ultra to Silkolene in the Type-R...?
Its up to you, we do rate the Silkolene over the Castrol as a "performance" oil.
Cheers
Guy.
