Now then, nothing like a good oil debate to get us all going eh??
But seriously, Bushman’s great thread on his seized rockers further provoked a question I had already had for some time.
Am I correct in thinking that the factory specify Silkolene oil?
If so, is that what y’all running with still?
I had bad experience with Silkolene breaking down and loosing its viscosity, resulting in low oil pressure. This was using their top synthetic, it was in hot conditions on a highly tuned BSA/Tri triple.
Oil pressure dropped to an alarming low, after checking what I could, I thought my bottom end was shot. But I checked out on line and saw lots of posts claiming that Silkolene degraded quickly, so I changed the oil for Red Line and, bingo, all was well!
I realise that Silkolene (and thus Fuchs) are big companies that should know what they’re doing, so I’m sure their products are good in many applications. But my personal experience of a highly tuned old fashioned air cooled engine, run hard, in hot conditions, was pretty conclusive, and I have since spoken to other classic racers, who voiced similar experiences.
