<DIV>I run 30W non-detergent in my BN1 and that's what's been used in it for
over sixty years now and it still works great, so why mess with a good thing!
And yes, mine leaks, so I always have fresh oil being added and what leaks,
looks almost brand new. All good and I try not to over think or change what
works.</DIV>

the gearbox oil level. On unscrewing the plug the hot oil<BR>flowed out under
