I've often wondered why some BritCar makers specified motor oil for the
gearbox rather than gear oil. The two types of oil are formulated for
very different types of protection, and theoretically motor oil doesn't
have adequate resistance to high-pressure sliding contact for use in a
gearbox.

Well, if you want to pick nits, "motor" is used correctly only as in
electric motor, while "engine" refers to internal combustion or steam
engines. OTOH, it does sound silly to say "enginecycle" instead of
"motorcycle"...
