[TR] GL5 in a diff

[Brian Jones]

Randall: is there no yellow metal in the diff (unlike transmissions) to be
concerned about pitting and corrosion, or if there is yellow metal there, is
the pitting/corrosion risk from GL5 overstated?

I have been using exclusively Valvoline SynPower (full synthetic GL5) gear

oil in all my Triumph diffs for many years.  Never any issues, and in fact I

credit it for making the axle in my TR3A (which was already well worn when I

got the car) last for the 150,000+ hard miles that I drove it.
