Does anyone use "real" oil in a Comet gearbox? With my background with industrial gearboxes, semi-fluid grease is 19th Century technology for water wheels and steam engines. Even mineral oil has been replaced with Castrol R, oops no that's wrong , with synthetic gear oil. Industrial gearboxes now have different selection charts for using mineral oil and synthetic, because the gear efficiency is so much higher with synth.
I'm about to strip and refurb my Comet gearbox, why shouldn't I use synthetic oil???
