Tech Tips for your Model-A
Choosing the right gear lube::
"600W" oil was used in Model-A transmissions, differentials, and steering boxes when they were first manufacturred. No doubt that in their early years the proper lubrication was used.
The "600W" was manufactured and distributed by suppliers for use in Model-A's for many years - then things changed!
The oil marketed today as "600W" is nowhere near the same viscosity ("600W" was not, by the way, the actual viscosity of the oil, it was just called that). It was closer to 240wt
What is sold today as "600W" is nowhere near the same.
Suppliers today offer oil that is called "600W" but it does not come close to 240wt oil.
Combining the "600W" oil sold by suppliers today with STP motor oil additive (on a 50/50 basis) produces a reasonable substitute for "600W" oil.
Straight STP (used by some) is generally not recommended for this application!
