600W Transmission & Rear Axle Oil, 1928-1948, M-400

Approximately equivalent to SAE 250. Also used in steering boxes.1 quart plastic bottle with pour spout. We offer 2 versions of this oil . This version is our preference and although it has a higher cost than our other offering M-400-L, it has slightly more viscosity. See more explanation below. However, both versions are proper for use in all 1928-1953 Ford cars & pickups.
SKU: M-400

With the minimal use of seals & gaskets in their transmisions and steering boxes, Ford counted on the use of this heavy oil for no (or minimal) leakage as well proper year round lubrication of the gears. This version is more costly than our other oil offering (M-400-L) but M-400 has a slightly heavier viscosity and thus more effective in leak prevention.

For use in transmissions (2 3/4 pts), rear axles ( 2 1/2 pts), and steering boxes. 3 quarts (6 pints) required to do all 3.
