Classic car gear oil

[bazjude2998]

Advice please.
TVR Grantura ,MGA Engine & Gearbox.
I have been informed modern GL4 & GL5 gear oils have additives that can damage bronze internals.The advice is to use Morris Lodexol SS 75/90 Semi Synthetic .
All opinions greatly received ( Does that mean all brands of SS 75 / 90 because nobody stocks this product of Morris locally )
Thanks Baz

Get Morris Oils on the phone they are helpful enough they certainly was when I inquired about their zinc/ZDDP levels in a classic motor oil they make for a customer's classic

Doesn’t MGA use engine oil in the gearbox like MGB?

There is a lot of internet talk on bronze internals and EP lubricants.

You are bang on
Engine oil in gear box but I,m guessing there may be bronze in the diff
Having said that It’s interesting information cos I reckon ther,s loads of classics running with gear oil that may damage internals
