40 stories down, in caverns no tourist will ever see,
lies the secret of the quicker starts you get with today's
Super Shell the gasoline for top performance
The 9 ingredients in today's Super Shell are specially
blended every season to give you tep performance in
any weather. ,
While colder, harder-starting mornings are here,
today's Super Shell is primed with extra Butane an
ingredient so volatile it has to be stored under pres
sure all summer to stop it from vaporizing by itself.
Think what this high volatility means on cold days.
Faster firing. A big strain off your battery. And an
even bigger one off your patience.
IT takes millions of gallons of Butane to
give today's Super Shell its nationwide
reputation lor quick winter starts.
. But you might wonder why Shell goes to
lo much trouble to store this quick-start in
gredient underground. Mere's why.
' Butane is stored as a liquid. But it is so
eager to vaporize that it lias to be kept under
pressurc.This can be done in tanks ol course.
But Shell's refinery experts decided that a
cavern would be safer and more economical.
They didn't have a cavern handy. So they
built one.
It was no mean task. For instance, the
whole cavern had to be leakproof, airtight
and had to have the smallest possible open
ing (sec cut) that could take men and ma-:
chtnery. This tiny entrance posed quite a 1

Blasted out of solid rock, this Butane storage cavern is located 432 feet straight down beneath total area that's larger than two football fields and holds 22 million gallons. Storage space consists

problem when it came to getting a bulldozer
down. But our "spclunkcrs" simply cut up
the bulldozer to fit the hole.
The very thing that makes Butane a prob
lem to store makes it work wonders in stone
cold engines.
Lou' tciiiifirtliircs make ordinary gaso
line reluctant to fire. But when you add
Butane, volatility increases dramatically
and even the coldest engine finds it
easier to start.
That's why an extra dose of Butane is added
to today's Super Shell whenever the weather
is likely to be wintry. It takes a strain off
your engine, your battery and your patience.
Butane lins hot-weather benefits,
too an odd little paradox
Shell's refining experts always add a certain
amount of Butane to Super Shell even in
mid summer. This may sound paradoxical.
But it isn't.
Volatile Butane also happens lo have an
unusual anti-knock value at high tempera
tures. So this winter-start ingredient has a
summer benefit, too. It helps to smooth out
your car's performance just as much in June
as it docs in January.
Now that you know about Butane, why
not take a couple of extra minutes and learn
about'the eight other ingredients in today'
Super Shell? It's essential reading if you
want to know the seSrct of toj pcrormiwce.

Ingredient 2 is TCP for power,
mileage and longer plug-life
Super Shell now contains an even better
version of this famous additive. Its chemical :
name is cresyl-diphenyl-phosphate. ' '
TCP additive can give your car up to
15 per cent more power; up to 17 extra
. miles per tankful; and can make plugs
last up to twice as long.
New TCP does this by neutralizing certain
harmful effects of combustion deposits. It is
scientifically formulated to keep them from
glowing when hot a major cause of power
loss. Also to keep them from diverting your,
spark a major cause of "missing."
Ingredient 3 is "cat-cracked"
gasoline for power with a purr
This is petroleum that has actually cracked
under 900-dcgree 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 moleculcs-wilhout changing itself.
Ingredient 4 is Alkylate, noted
for knock control in hot engines
Jimmy Doolittlc 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 eteii faster than the engines
oaDC-7.
Ingredient 5 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 cats like
musicians. ,
. They insist -on adding a special anti
knock mix. A mix, so effective, one tea-.
spoon per gallon can boost anti-knock
rating by five points. .
This mix has the tricky job of rcgiintiiig
' combustion so that Super Shell gives each
piston a firm, even push rather than a
sharp blow which would cause a knock.
Ingredient 6 is Pentane mix
for fast warm-ups on cold days
. Pentanes arc made by tearing gasoline apart,
much as you split kindling to start a log fire.
,' In this case, the "logs" are petroleum's
heavier hydrocarbous. 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.
Carburetor Icing causes stalling. Arrow shows
where ice can form on your throttle plate.
Shell anticipates this problem, See below.
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-live degrees, a carbu
retor anti-icer is added.
Why 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 thcpurcstgasolinccan 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.

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.
These three alone release 1 1 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 Iojj performance.
