Classic-Cadillac-Fuel consumption?

[00"Enjoy the Moment"]

Dear Members of this Forum,

I am very happy to have found this nice forum, so that i can find some answers to my questions.
I am writing a book about the internal combustion engine and cadillac has contributed
very much to it with developments like the first electrical lighting and ignition system (1911),
the first successful mass-produced V8-car (1914) or the only successful V16-car in automobile-history (1930).
What i search for are the fuel-consumption-data of the early Cadillacs.

I would be very obliged if you could give me these information,
or an email-address of someone who knows it.

Particularly interesting for me is the fuel consumption of...

...the 1914 Cadillac Type51 (first V8)!!! -> very important!!!
...a V8-Cadillac of the 1920's
...a Cadillac V16 (1930-1936) -> overhead-valves
...a Cadillac V16 (1937-1941) -> sidevalves
...a Cadillac V12
...the Single-Cylinder Cadillacs from 1903-1908
...a Four-Cylinder Cadillac until 1914

I am grateful for every fuel-consumption-data you could give me.

Thanks in advance for your efforts.

I wish you a very long and lucky life.

sincerely yours
Ronny Grobheiser
