[Healeys] Gearbox oil

[Oudesluys]

If there are bronze/brass baulk/synchro rings in the gearbox it is best 
to be on the safe side and not use EP oils that contain halogens F, Cl, 
Br, I as these may attack the bronze/brass components. Sunbeam for that 
matter stipulated to use SEA 30 or 20W50 engine oil. I do not see a 
reason to take the risk using EP oils. They do not ad much if anything. 
Straight or detergent containing does not matter much if you change the 
oil on a regular basis as prescribed in those days. Oil is cheap so I 
change the oil in my gearbox every time I change the engine oil, i.e. 
once a year. Use a drain plug with a magnet.

Modern gearboxes may not even have a drain plug as the oil is never 
changed and we have become used to that!
