I have an old 1976 Seagull outboard engine which needs 140 grade gearbox oil. The gearbox gets filled with a little water, emulsifies and goes to sludge, which is fine, that's just how they all work. Every 10 hrs of use, you top it up and it runs lovely. 140 grade gearbox oil is £15/litre, I have been given 15 litres of brand new 20/50 engine oil, (for vintage cars.) I don't have a vintage car and was wondering if I could use it in my Seagull gearbox? Anybody have any oil knowledge?
Much appreciated. Paul.
