>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.
Hmm, and yet gear driven camshafts have similar high-pressure sliding
contact. My belief is it has to do with the viscosity and the operation of
the synchros.
>it does sound silly to say "enginecycle" instead of "motorcycle"...
And to end on a humorous note:
In 1894 a Chicago newspaper sponsored a motor race, and as part of the
promotion ran a contest for readers to write in their suggestions for a new
name for these "newfangled vehicles" to replace the commonly used term
"horseless carriage". The winning entry was "Moto-cycle".
