American Hammered Piston
Rings-We have sold more than
400 sets of rings since we started
in business last May and have not
had a single comeback.
Over 81 per cent of all the cars
on the highway are Fords, Chew
rolets and Plymouths.
It is estimated that 81 per cent
of all the motor car mileage is
driven in Fords, Chevrolets and
Plymouths. Sixty-five per cent of
all piston rings sold for replace
ment are for Fords, Chevrolets
and Plymouths.
And $1,000 miles on the Roose-
welt Raceway Mystery Run under
AAA contest board supervision
proves the Flexible Oil Cutter
Piston Ring an outstanding re-
placement ring for Ford, Chevro-
let and Plymouth.
Here's how the contest was run:
The AAA contest board purchas-
ed three used cars from dealer
stocks. 1885 Ford, a 1885 Chew
rolet and 1885 Plymouth.
The test was made by absolute
ly unbiased officials and drivers
of the AAA contest board who
purchased the materials, made all
mechanical installations and adj
justments, did every mile of driv-
ing and made all tests and re-
ports.
No manufacturer of motor cars,
parts, equipment, accessories or
supplies influenced any phase of
the tests.
The contest board selected the
Roosevelt Raceway for the COM
petitive tests. 1t was selected be-
cause it presented nearer average
driving conditions that any other
speedway or track in the United
States.
For the first run the Ford, the
Chevrolet and the Plymouth were
driven 1000 miles each exactly
as purchased. At the end of the
run accurate measurements were
made by the board to determine
exact oil consumption and the
condition of the engines.
Then the Big Three were equip.
ped with new rings.
Competitive makes of rings
were purchased by the .AAA from
regular jobber stocks. The rings
selected for the tests included the
various types of flexible rings
made by nationally known piston
ring manufacturers. These pur-
chases were made by the AAA
contest board from bona fide
sources of their own selection. All
installations were made solely by
the AAA contest board mechanics,
exactly according to the respec-
tive manufacturers recommended
tons.
For the second, third, fourth
and fifth runs the cars were
equipped in like manner with a
new set of piston rings for each
run and on each run were
driven $500 miles at an average
speed of As miles per hour.
At the end of every run the
engines were taken down pre-
else measurements taken and new
and different rings installed.
Each piston ring ran 1900 miles
in each car.
Same cars, same speed, same
oil. same drivers, same highway,
same conditions, but Not The
Same Results.
American Hammered Flexible
Oil Cutter bettered the consump-
ton of Manufacturer AS rings by
89.5 per cent; bettered the oil
consumption of Manufacturer BIS
rings by 96.2 per cent; bettered
the oil consumption of Manufac-
turer C's rings by IT. per cent;
bettered the average of all three
by 58.6 per cent.
That's why American Hammer
ed Distributors will get more of
the piston ring replacement bust
ness for Ford, Chevrolet and Ply
mouth.
The AAA contest board is the
automobile industry's supreme
court of performance claims. Its
supervision makes any automo-
bile event official.
The AAA contest board super
vises all leading automobile
events. 1t is the governing body
of the annual 500 mile Decoration
day speed classic at Indianapolis
The Roosevelt Raseway Mys-
terry Run was the first competitive
piston ring test ever supervised
by the AAA. It established a new
basis for unbiased protesting Of
