Hey Guys,

What weight gear oil are you running in your transmission and rear end gear boxes?

Gary WA · 06-13-2022, 10:47 PM

600w from Model A vendors,Others will have different oils

bavArian · 06-14-2022, 05:02 AM

SAE 250 GL1/2 from a German brand. (Rektol Klassik)
Using it for gearbox, differential and steering box. No complaints.

Patrick L. · 06-14-2022, 05:31 AM

Either 140 or 250 in transmitter, steering box. Anything from 80-250 [ or 600W] in the rear.

I use SAE 85W140 GL5 Super Tech Gear Oil from Walmart in the transmission and differential.

Patrick L. · 06-15-2022, 05:47 AM

You could try a lighter weight oil in the transmission, I just find that I don't like the way it shifts.

Stalube 140 Gear Oil

Sunny the Model A · 06-18-2022, 01:51 PM

600w steam cylinder oil. exact same stuff the model a suppliers sell, so I get it in 5-gallon buckets. no complaints except my diff is weeping oil from the bottom. no biggie, just got to keep an eye on it.

Kevin in NJ · 06-20-2022, 07:14 AM

That is not the weight of the oil but a type of oil.
Back in the 30's it was call 600W and is just a heavy pressure steam oil designed for straight cut gears. Today it has a different reference but people have researched the current naming.

Yep, 600W is a designation for the old steam cylinder oil. It works out to about 180-240 weight.

This is what I use: https://lucasoil.com/products/engine...oil-stabilizer It makes a huge improvement in tranny feel. Smoother shifts, slick feel to shifting, quiets gear noise. I've had it in my A tranny for years now, no comparison to the vendor 600W sludge.

eagle, Do you use that product straight or blended with something else?

WHN · 06-21-2022, 07:25 AM

I have been using a mix of 50% 600W oil and 50% STP. No leaks, shifting is great, works for me.

Enjoy.
