Gearbox oil

For now, I lumped all the pre-war cars together, I would LOVE for there to be enough demand to split it into groups (hint...hint, post here about your pre-war Singer)

Gearbox oil

Postby ColinB » Thu Dec 22, 2016 12:22 pm

The 1929 Junior Owners Handbook specifies Price's Motorine Amber B for the gearbox and rear axle. This is different to the specified engine oil which is Motorine D. What is the modern equivalent for Amber B and/or what do you all use? I presume a 90 grade non-EP gear oil would be suitable but thought I'd check.

Dick Preston agrees that SAE 90 is the right oil. I have ordered Penrite's Transoil 90 for the gearbox and the rear axle. Dick also recommends putting the minimum in the gearbox to just half way up the layshaft. This will apparently help avoid leaks and aid smooth changing.

Update from Dick - he has found a note that says the gearbox requires 1 1/4 pints. So it's easy to get this right: take off the gear stick and cover, pour in the oil and replace the gear stick.

Hey Colin,

I can also vouch for Penrite products. They are excellent. Their steering box lube works wonders in the pre-war steering boxes as well.

They have a very good reputation Phillip and their products are apparently used in important veteran and vintage car collections. I plan to put their oil in the engine after a few runs with the current fill of Halford's Classic.
