Sewin, I don't trust MMC's info on oils, as I suspect there's some copy & paste used in the manuals so old data gets accidentally used in newer versions
chatting with Billy Bellinger many years ago about the Aussie spec BTR's he advised Castrol SAF-XJ 80/140 "and add a spash of friction modifier sold by Jag service depts"
That particular Castrol spec seamed to morph into Syntrax, but then I swopped to Millers because of the tech support & I especially like to support a British manufacturer that makes a quality product
