| The instructions were prepared by
Ray F. Mcnamara, the famous Max.
well road engineer and the world:
most experienced motor car pilot
In his advice Mcnamara, who ha.
driven over 100000 miles at the
| wheel, lets loose a series of helps
that are educational in value for mo.
torists generally and of such sur.
| prising nature, considering the ex-
| perience they are based on, that the

distribute them to automobile own
ers everywhere.
DO not change a thing in the
stock cars as you borrow them from
their owners for your rum" Mona
mara points out in His instruction
sheet See that you have a fair
compression in each cylinder, use a
speed of Is miles an hour, don't
tamper with anything the factory has
put into the regular stock car, and
YOU will be certain of about 80
miles from your one gallon of fuel.
With practice on your course and
careful driving you can do anything
from 80 to As miles per gallon.
DO not make your run with high
test gasoline. The stock Maxwell
motor is engineered to run best on
ordinary gasoline bought at the
street filling stations. High-test gas
gives more power but less mileage.
Do not change the factory dash ad-
justments in the least. Contrary to
theories, too, lean a mixture cuts
down from two to four miles on the
gallon.

the regular Maxwell carbuetor
Leave the float level and the needle
taper exactly as the factory engi-
neers have made them. Do not
change the valve timing and do not
attempt to change the valve setting.
If the car has been run 5000 miles
or more you need not grind the
valves. Carbon deposit will not af-
feet your mileage either way.
BE assured that l have made
gasoline economy demonstrations
with MaXwells in every part of the
United States, with my record to
date being 45.6 miles on one gallon,
and have yet to discover a way in
which I could improve upon what
our engineers have given the regu-
lar stock car. have tried to bet
ter them, but have lost mileage in
every instance. Stick to the regu-
lar stuff and any owners Maxwell
will do the rest"
McNamara's instructions were
sent to Detroit from Los Angeles. In
the contest demonstration upward of
5000 Maxwells will participate, each
mount being an owners machine.
Each of the dealers entering is re-
quired to run two owners cars to-
gether over the same route, with
three official observers in each car.
