Oil Burns Slowly.

'On the other hand the heavier fuels

tically did away with the intake mani

and close to the intake On the in
terror of the cylinder head we converted
the Stephens manifold into a super
heated chamber and built a yapOrlginC
wall directly in the path Of the gas.
This wall is heated by the direct eX-
haust of the two center cylinders. This

This prepared gas Is held waiting in

chamber. This permits only perfectly
prepared gas TO enter the cylinders. the
kind that ignltes quicker. cNplodes
faster and burns completely before the
valves open for discharge,
The results prove that we found the
correct solution. One 81 the most strik-
ing demonstrations Of Stephens success
was the famous run between Camps
Fremont and kearney and return. Of
1,191 miles in 40 hours and 10 minutes
made on distillate, without stopping the
engine. The Stephens has also won the
Los Angeles economy run two years In
succession and tests prove that the
stephens Is the most powerful and
economical engine for it's size found in
passenger automobiles, developing 81
horse power at $500 r. y. NJ.
AS far as IL is possible for @any
maker TO do so, we have successfully
checked the, fuel bhgbear with the
stephens perfected overhead valve en-

"A Stephens Salient Six has made he
run from Sacramento TO Lake Tahoe in
the record time OF three hours and eight
minutes, stripping Il minutes from the
record held by another we'll known car.
The course is 10 miles long over
what IT, unquestionably the most won
deTful mountain highway In the world.

Sierra Nevada mountains to an altitude
Of 1900 feet. girded with a wealth OF

then downward to beautiful Lake Ia
hoe.
Over this road Al Kennedy. OF San
lose. drove a stephens Salient six at
an average speed Of 3a62 miles per hour,
lowering tho former record by IA min
utes. q
Tho most remarkable part of the per
foFmanee Is the fact that up TO the day
before the race MIR. A. Il. Mcmahon,
Stephens distributor at Sacramento,
who had entered the Stephens In the
race. was unable to secure a car to
participate. Finally he borrowed a
stephens from George Knox, Sacrament
to PHOTOGRAPHER, who q year. and a half
before had purchased the first stephens
shipped TO that city.
Called Game"
Mr.. McMahon wa called the gamest
man on the continent, when he an
nounced that he was going to use the
Oldest Stephens Salient Six In the To-
cality in the, speed event. Later II de-
veloped that Mr.. Knox's Stephens had
never been o~verhauled nor ever had the
valves ground since he had purchased
1t II months before.
MY faith In the road performance Of
the Stephens Salient Six regardless OF
its age or service previously rendered
and its ability to make the run in rec
ord time has been justified" aid Mr..
Mcmahon after the race. We had no
trouble of any kind and the Fisk cord
tires which are now regular equipment
showed they had the stuff IN them,
Considering that MIR. Kennedy had only
been over the difficult course twice be
fore the race this demonstration OF
speed. stamina, endurance and mechan-
ical perfection is striking proof Of the
fact that the stephens is a master all
round road performer, You can't beat
tem.
Old racing fans who were on the
ground ut the finish declared that they
had never seen a car wind up In such
condition. This is a wonderful tribute
to the mechanical perfection OF the
Stephens Salient Six engine.
