Which oil is used in the Hydro-Vac brake booster?
I'm trying to find out which type of oil to use in the Hydro-Vac brake booster of a 1951 F7. The manual says air cylinder oil M-4856. Thanks!

I asked Google your question and found at least one thread on a military vehicle website that deals with exactly your question:

Mineral oil, neetsfoot oil, shock absorber oil, any oil that is compatible with leather. Use about 1 oz. in your unit. Check annually depending on use. Don't use engine oil.
Good luck in finding this:
