[Spridgets] Motor Oil in the Gear Box

That's not the case for gearboxes in general, though it might be for a  
Spridget box but I doubt it.
 
There are lots of gearboxes where you must use a synthetic oil.

The  issue with synthetic in a gearbox is that it tends to be too
slippery for  proper operation of the synchros, leading to lots of
gear-crunching shifts.  I lean towards 20W50 myself.
