[TR] manual gearbox oil Hypoid 75W

[John Macartney]

Couldn't agree more. That was the oil spec in the days when the Stag and all
other Standard-Triumph models were in production and that was the factory
recommended lube. Over all the years I had my own classic cars I never
deviated from factory oil specs - because all of them, unlike many modern
oils were made to meet the engineering tolerances of the day whereas with
more modern lubes (as they affect the UK and Europe) many are completely
unsuitable, a costly waste of money and of questionable benefit. Just
because an oil is *modern* does not mean it's better than its forebear. It's
horses for courses IMHO

Sujit,

Reading these posts made me remember that I did have my OD Stag gearbox
rebuilt about 10 years ago and I refilled it with Castrol Hypoy 80W90 from
dry.  Works great, shifts smooth, OD operates fine, no issues.  Thats what I
would use if I were you.  Its not exotic and readily available.
