Every part of your vehicle
has been meticulously designed,
so you need to use a lubricant
that is just as well designed
to protect it.
Shell Lubricants engineers
have developed Shell Spirax,
a world-class transmission range
of axle, gear
and automatic transmission fluids.
They enable drivers, fleet owners
and owner-operators
to select the oil that
will deliver Shell's optimum value,
through enhanced wear protection,
long oil life and efficiency.
Protecting components is even more
relevant in harsh driving conditions.
Experts believe that most of the wear
in a gearbox occurs during shifting,
high-speed operations
and at start-up.
In fact, this occurs in the very
first seconds you start your car.
While the oil rests in the sump,
the gears start turning and meshing,
resulting in the inevitable race
between any mechanical stress
and the oil aiming
to prevent it happening.
A top-tier synthetic oil
has a flatter variation of viscosity
with temperature,
compared with
a conventional lubricant.
This gives benefits both at
lower temperatures - less friction -
and at high temperatures -
more protection.
This means that...
..leading to less mechanical stress
and a longer gearbox life.
Transmission lubricants
are as crucial to the transmission
as motor oil is to the engine.
The most important function
of the oil in a gearbox
is the reduction
of the friction and wear
which harm metal surfaces,
leading to premature failure of the
moving and rotating metal components.
In some cases,
they become denser than is needed
and energy is wasted
moving this thicker lubricant film.
Top-tier synthetic lubricants
control this thickening
and can reduce friction by up to 30%.
Over time, oils will degrade.
High oil temperature
will accelerate this,
but the lubricant's resistance
to oxidation
will help to slow it down.
Oil temperature is influenced
by ambient conditions, speed
and torque of the transmission
and friction.
Put simply...
Due to their molecular composition
and lower friction losses,
synthetic transmission oils
typically enjoy
as much as
a 10 to 20-degree-centigrade
lower temperature
compared to their mineral-oil-based
alternatives.
With oxidation accelerating
in higher temperatures,
well-formulated synthetic lubricants
also offer
improved oxidation stability,
reacting with oxygen from the air
at a slower rate than a mineral oil.
The resulting 20-degree-centigrade
reduction in operating temperature
can typically allow
premium synthetic oils
to last up to two to three times
longer than a standard mineral oil,
rising to five times
in extreme cases.
Whatever your vehicle needs,
Shell can provide a wide range
of lubricants and services
that help you stay efficient
and well protected.

to find out more about the full range
of Shell Spirax, axle, gear
and transmission fluids.
The cooperation with Shell
that we have
brings a lot of knowledge
to our development process.
We are not chemists.
We don't develop oils.
We develop the components.
We need cooperation
to develop the right formulation
for the transmission oil,
to gain both fuel efficiency
and the durability
that the customers need.
The transmission oil
is a key component in the gearbox.
It's like the bearings of the gears -
we need it.
I'm very happy
with the support that we get
from the Shell Lubricants specialists
in this development process.
They are able to combine
the fuel efficiency benefits
that we want to give to our customer
with the durability
that they also need.
