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.
