[H. L. Chauvin]

FWIW:

I had an Uncle born in 1905 who worked or cars all of his life, and was manager and supervisor of a car dealership from the late 1920's through the early 1940's.

He told me back in the late 1950's that when dirt and gravel roads preceded paved roads, without air and without oil filters, vintage cars could travel about 8,000 miles prior to beginning to burn oil, beginning to have nauseating crankcase fumes, and exposing embarrassing smoke exiting the the tail pipe.

After engine wear, some responsible car owners requested engine re-builds, others thought nothing of continuing to drive around with worn out engines, thus resembling mosquito control vehicles smoking up the neighborhood.

Today, (2017), amounts of unfiltered harmful surface grit entering engines, (on today's paved roads), are not distributed in uniform amounts all over the U.S.

Lots depends on wind and soil conditions adjacent to today's paved highways, and also on numbers of vehicles leaving side dirt roads and industrial plants and tracking various harmful particles on paved roads.


There will always be a few Model A concepts that will always be certain:

A. Rather than add a Model A oil filter, and a Hi-Boy 6" K&N air filter, most Model A owners will continue to try not to spend money in order to see what they can get by with; and,

B. Others drive so little each year, as current seniors, they know their Model A engines will outlast the current owners ..... so why add filters?

C. Excuses for not filtering Model A engines will always be based on repeated Model A Forum conjecture.

D. Some have show cars and only want originality.


Suggestion: Respect every Model A opinion, drive and have fun ..... it is far later than any of us think.
