Hmm. The concensus here seems to be to use
20/50 or 30 weight oil. I'm just curious what you all think of the following
statements, found on this web site:
http://www.a-series.org.uk/inline_gearbox.htm
"Modern gear oils are much, much better, so if you want that quiet 1st gear
to remain quiet, don9t put engine oil in the gearbox. Engine oils and gear
oils are now quite different, having large quantities of different additives
designed to perform completely different tasks, and most engine oils are
simply not suitable for the gearbox."
and,
"To cut a long story short, modern engine oil is unsuitable, as are oils
designed for hypoid back axles. An API GL4 specification gear oil is best,
such as "Castrol EP-80" (SAE 80W); furthermore this oil has the right
viscosity. EP-90 would probably also work well, particularly if a thicker
oil was desirable (leaks or noise). GL5 oils are high in sulphur, and should
therefore be avoided"
