The 74-day
Ferrari ‘Magic India Discovery’ Tour reached its
conclusion at the famous Gateway of India in Mumbai
recently. During the trip, two Ferrari 612 Scaglietti,
one red, the other ivory, both sporting a specially
designed livery, travelled over 13,000 kilometres and
visited 57 cities – all without an oil change. At the
end of the tour, Shell sent samples of the used Shell
Helix Ultra motor oil for analysis.
Lubricant is the
lifeblood of the engine. Its job is to help keep the
components clean, protect the moving parts from mechanical
wear, reduce friction and power loss, and to cool the
engine. Shell Helix Ultra also contains active cleansing
agents to help prevent dirt build-up and ensure optimal
performance.
“The Ferrari
‘Magic India Discovery’ Tour gave us a unique opportunity to
put Shell Helix Ultra 5W40 to the ultimate test,” explains
Mark Wakem, Shell Lubricants Development Project Leader for
Ferrari. “Not only did Ferrari deliberately choose to leave
the oil unchanged, the cars experienced very harsh driving
conditions, including dust, more than 45°C temperatures and
slow speeds due to unsealed roads and the multitude of
traffic. The analysis results are exciting for Shell because
it demonstrates that despite the challenging conditions, the
oil has performed - and is still performing - remarkably
well.”
The Ferrari 612
Scaglietti owner’s manual recommends that the first oil
change take place after 10,000 kilometres or one year. The
oil change interval extends to 20,000 kilometres or annually
there after. In the build-up to the Ferrari ‘Magic India
Discovery’ Tour, the two Ferrari 612 Scaglietti completed
around 5,000 kilometres in pre-testing and preparation,
which when added to the tour distance, is a total of 18,000
kilometres. In normal driving conditions, the two cars would
be coming up on their second recommended oil change. To
check the health of the engines, the Ferrari technicians
checked the oil carefully on a daily basis throughout the
entire tour, and were very pleased with its performance.
“In
collaboration with Shell, we made a deliberate decision not
change the oil within our recommended timeframe,” explains
Ferrari engineer Andrea Costantini. “We knew that this would
give us the chance to test and evaluate the engine in the
tough conditions of India. We have been working with Shell
for a very long time, many years, and we trust them, so we
knew that the oil would not let us down on tour.”

FINDINGS
“What
immediately stands out is that the analysis results for both
612 Scaglietti are almost exactly the same,” says Wakem.
“This is fascinating, because it is very rare. Despite the
two cars having made the same journey, normally you must
still allow for variations in engine manufacture. What we
can assume here is that Ferrari’s precise approach to engine
building means they have truly created identical twins. It
also clearly demonstrates the consistency of the Shell Helix
Ultra oil, across two different vehicles.”
·Vk100°C
(Viscosity)
The normal
viscosity at 100°C for 5W40 grade lubricant is between 12.5
– 16.3 mm2/s. These results show that while, as expected,
the oil has thickened a little due to oxidisation, the oil
in both cars is still easily within grade. This means the
oil is still remarkably robust, showing excellent shear
stability. Put simply, it is demonstrating a high resistance
to degradation caused by mechanical forces in the engine.
·TBN
(Total Base Number) and TAN (Total Acid Number)
We usually look
at TBN and TAN together in order to understand the levels of
acidic combustion products and base reserve in the oil. If
the oil is doing its job correctly, the TBN will drop as the
base reserve in the oil is used up in neutralising acids
produced during combustion. This acid build-up is indicated
by the increase in TAN. If TBN is allowed to drop too far
and TAN rises to unacceptable levels, at some point a
corrosive attack on engine components may start to occur.
The wear element analysis results show that this has not
happened and that the oil is still protecting the engine.
·Fuel
Dilution
Fuel dilution is
a measure of how much fuel is seeping through into the oil
during combustion. It is usually caused by excessive ring
wear, which happens if the lubricant is not doing its job
correctly. This wear is caused by dirt and acid corrosion.
What is excellent to see from these results is that the fuel
dilution is around 1% in both cars, which is well within the
healthy limit – a particularly good result given the dusty
conditions in India. This result indicates the Ferrari
engines are in very good condition.
·Additive
Elements
A number of
different additives are put into Shell Helix Ultra motor oil
for various purposes. Zinc and Phosphorus are key anti-wear
components, helping to lubricate and protect the surfaces as
they move together. Calcium is a key part of Shell Helix
Ultra’s active cleansing technology, helping to prevent the
build-up of dirt inside the engine, a factor in preventing
power loss. The good news is that these results show the
additives are still robust and working well, despite the
challenges posed by the roads of India.
·Wear-related
Elements
The best word to
describe these elements is ‘contaminants’. These are foreign
substances, either rubbed or corroded off parts of the
engine or sucked in from the road outside. These results
show that normal wear metals like Copper and Lead from the
bearings and Iron and Aluminium from the pistons, conrods
and engine block are all present at acceptable levels, which
demonstrates that the oil is working well.
In addition to
the expected wear metals there are also two other
contaminants present - Silicon and Sodium. Silicon is an
element contained in sand and also, clay, which is
predominant in parts of India. Given how extensive the tour
has been, it is not surprising to see significant amounts.
Clay in its driest form creates a very fine dust - like
talcum powder - which can even thwart the cleverest Ferrari
air filter. The second
contaminant, Sodium, is essentially from salt. Again, this
can be picked up from dust. Particularly high sodium content
will be found in dust around coastal areas, such as those
visited by the tour. Salt can have an especially corrosive
effect on an engine, so the job of the oil to neutralise it.
“We did not have
a single engine concern during the tour,” Costantini
commented. “These results are very interesting, because they
show that the Shell Helix Ultra motor oil was working
perfectly, but they also show how well the Ferrari engines
performed under very tough conditions. This was the aim of
the Ferrari ‘Magic India Discovery’ Tour - we wanted to show
that a Ferrari can handle any challenge.”
Over 60 Years of
Shared Passion for Performance
As early as the
1930s Shell was helping Enzo Ferrari go racing, so it was a
mark of esteem when Shell was chosen to supply fuel and
lubricants to the company he founded in 1947. Today, Shell’s
technical partnership with Ferrari is an essential part of
its overall design and development strategy, as it seeks to
create better products for the road. In fact, every car
leaving Maranello is first-filled with Shell V-Power fuel,
Shell Helix Ultra motor oil and other Shell products to
create a complete package of engine care.
