Weird electron "pictures" help Shell scientists
develop improved TCP for today's Super Shell
to give your car top performance
Read how electron diffraction revealed the inner
secrets of the combustion deposits in your car's en
gine. How improved TCP was developed to neutralize
these deposits, prolong spark-plug life, increase mile
ageand release up to 15 more power.
Here's the full story of today's Super Shell and
the 9 ingredients that give your car top performance.
The TCP iii toduy's Super Shell does its
job better than ever. It neutralizes cer
tain harmful: effects of combustion deposits
deposits that can prevent you from ever
knowing your engine's top performance.
There's not a single engine with more
than a few thousand miles on it that doesn't
have this type of deposit in its combustion
chambers, These depusits can cause real
trouble when you need power most.
.They glow red-hot and set off the fuel
before the spark plug has a chance to get
into the act.
The experts call this pre-ignition. The ex
plosion punches the piston on the way up.
Two forces meet head-on. No wonder your
power falls off.
Deposits can also cramp your car's per
formance by short-circuiting the spark. What
happens? No firing you get a miss.
Problem: How to add something to gaso
line that neutralizes the effects of deposits.
Answer: Shell Research. ' ,
A scientific detective story
Shell scientists announced the first TCP
. additive eight years ago, after research had
proved it could virtually end this misfire
problem once and for all. TCP was hailed
as the greatest advance in gasoline in thirty
one years. Now Shell has improved it.
Scientific detectives like the electron
"photograph" (above) made new, improved
TCP possible. They helped Shell scientists
to 'look engine deposits right in the fucc. And
to find how best to neutralize them.
Test proves how TCP neutralizes glowing deposits. The electrically heated piston, above, has been
sprinkled with two kinds of engine deposit. The glowing deposit, at left, had mil been neutralized
with TCP. The deposit on the right had. With TCP in action, there is no trace of glow.

What today's TCP can do
Tests have already proved that TCP can
help you. get up to 15 per cent more power,
up to 17 more miles per tankful. And it can
make plugs last up to twice as long.
Yet TCP is only one of ine ingredients
in today's Super Shell. Read about the
others. And how each helps your car deliver
its top performance.
Ingredient 2 is "cat-cracked"
gasoline for power with a purr
This is petroleum that has actually cracked
under 900-degrec heat and catalytic action.
Its heavier molecules have been shattered
into livelier, lighter ones.
The result is a super-octane ingredient
that makes your engine purr with power the
moment you put your foot down.
note: "Cat-cracking" refers to the use of a
catalyst the mysterious substance that can
alter molecules without changing itself.
Ingredient 3 is Alkylate, noted
for knock control in hot engines
Jimmy Doolittle helped pioneer this out
standing high-octane ingredient for Shell
aviation fuel.
Alkylate the ingredient that took the
dream of 100-octane gasoline out of the lab
and put it into the skies is now in Super
Shell. It controls knocking in hot engines
at high speeds better than anything else yet
available.
note: Speaking of controlling knocks at
high speeds, remember that car engines fre
quently turn even faster than the engines
of a DC-7. Think of this next time you pass
another car.
Ingredient 4 is anti-knock mix
for extra resistance to knocks
You might think that two high-octane ingre
dients are enough for knock-free perform
ance. But Shell's scientists have keen ears.
Ticy insist on adding a special anti
knock mix. A mix so effective that one
teaspoon per gallon can boost anti-knock
rating by five points.
This mix has the tricky job of regulating
combustion so that Super Shell gives each
piston a firm, even push rather than a
sharp blow which would cause a knock.
Ingredient 5 is Butane for
quick starts on cold mornings
Butane is so eager to get going that Shell
keeps it under pressure 400 feet below
ground to stop it from vaporizing by itself.
Think what this extra volatility means in
cold weather. Your engine fires in seconds. '
There is less strain on your battery. And
none on your patience. ,
note: Super Shell is primed with Butane
all year round. In winter, Shell scientists
simply increase the quick-start doss.
Ingredient 6 is Pentane mix
for fast warm-ups on cold days
Pentancs are made by tearing gasoline apart,
much as you split kindling to start a log fire.
In this case, the "logs" are petroleum's
heavier hydrocarbons. A special process
transforms their molecules from slow
burning "logs" into the quicker-firing
"kindling."
net result: Fast warm-up and top per
formance in a hurry.
Ingredient 7 is an "anti-icer"
to check cold-weather stalling
Super Shell's formula is adjusted as often as
eight times a year to beat the weather. For
example, whenever the temperature is likely
to be less than forty-five degrees, a carbu
retor anti-icer is added.
Wliy add anti-icer at forty-five degrees?
Because, even then, frost can form in your
carburetor just as it does in your refrigerator.
It can choke your engine dead.
Ingredient 8 is gum preventive
to keep carburetors clean inside
Even the purest gasoline can form gum when
stored. This can clog carburetors and foul
automatic chokes. But, with Super Shell,
you needn't worry. A special gum preven
tive docs the trick.
o
.iTrndemark tor Shell, unique ciollnt
It acts like a policeman controlling a mob.
Regulates unstable elements to help keep
them from clotting. Hence no gum problem.
Ingredient 9 is Platformate
for extra energy, more mileage
It takes eight million dollars' worth of plat
inum catalyst for Shell to produce Platfor
mate. But fortunately for you and for us,
this precious stuff can be used over and over
again.
The platinum re-forming process, which
gives Platformate its odd name, converts
petroleum into super-energy components
such as benzene, xylene and toluene.
TJiese three alone release 11 per cent
more energy per gallon than the finest
100-octane gasoline.
But make no mistake. This is not untamed
energy. Far from it. The super-energy of
Platformate is harnessed by the eight other
ingredients in Super Shell, where it behaves
so well you scarcely know it's there. That
is until you note your extra mileage. After
that, there is no doubt.
Test Super Shell for yourself
Try Super Shell next time you fill up. You'll
soon feel and hear a difference in the way
your engine runs.
That difference is top performance.
