I replaced it with (I forget the exact brand) a synthetic gearoil with a
low viscosity/temperature variation, and it was impressively improved. The
gearbox had suffered over the years, but it worked perfectly well for
several years afterwards until everything else fell off and I traded it in.

I had a problem with the syncro on second gear graunching when selecting
at over 40mph (changing up or down). Had a chat with the bods who
service it etc, and they said that Shell had developed a gear oil that
was supposed to fix this problem and suggested I give that a try. Went
for a quick gearbox oil change, and it was like a miracle fix - it
restored perfect operation immediately and it has remained that way for
the last 65k miles. It was IIRC, "Shell Gear Oil S". It was about 10
quid a litre mind you!
