Oddly...we tend to be surprised by good news. I have had my A for three years and changed oil twice. It has NEVER seemed to lose/burn oil...even though there is a fine mist of oil under the pan which results in drips on the floor.
 
The dripping from my Model "A" is transmission oil, not motor oil. Annually I have to top off the transmission. I change the motor oil once per year & the oil level stays constant.
 
Every internal combustion engine consumes a small amount of oil. With each of its millions of strokes, this is simply a given for lubrication purposes. However, the amount is extremely small. (This is not to be confused with oil loss, which seeps out of the engine's crevices.)
However, water condensate accumulates in the engine oil, causing its volume to increase slightly. This often occurs with frequent short trips and when the engine is running at low temperatures (oil sump below 90°C). Consequently, the dipstick reading may not be lower, and it can mistakenly appear as if the engine hasn't used any oil at all.
This is easily noticeable when changing the oil after a long period of inactivity, as the first few shots of water will be present in the oil. Therefore, it is advisable to change the oil more frequently, especially with low mileage or short trips.
 
the model A was designed with leaks in mind.

you can find pictures taken of brand new Model A Fords on showroom floors that have oil spots under them. those leaky parts of the car will oil other moving parts.
-the wishbone
-the rear cross shafts on the first braking systems
-the ball on the torque tube
are a couple of spots that get the expelled oil. nothing is sealed up perfectly.
SO
if you A is not using oil that is super. don't try to figure it out.
 
I think saying "Should I be happy that my car uses no oil after four years" falls under the "I checked my bank statement and I have more money than I thought" category?
