Designed to give your diesel engine extra protection, extra performance and
extra efficiency.
Next time you visit a service station, look out for Shell Diesel Extra. If you
don't give it a try, you'll never know what you've been missing.
Shell Diesel Extra is a fuel with an exclusive formulation that is designed to
clean the engine. This can lead to better engine performance and increased fuel
economy as well as reduced emissions. Shell Diesel Extra contains a powerful
detergent, which helps to clean away and reduce the build up of the harmful
fuel system deposits that can collect in a diesel vehicle's fuel injection
system, reducing performance and fuel economy.
Shell Diesel Extra is also higher in cetane than conventional diesel. Cetane is
an indication of the fuel's readiness to ignite and a diesel fuel with a higher
cetane number will aid combustion. This can lead to the engine running more
smoothly with less noise and reduced emissions.
Research has shown that diesel drivers expect more from their vehicles and from
the fuel that they buy. Diesel is also a growing market in the UK : the diesel
car population has grown by more than 10% over the past 5 years. The new
generation of diesel engines for cars and trucks is particularly responsive and
can deliver performance , which matches that of a petrol vehicle. These new
engines may benefit from a higher performance diesel and that is where Shell
Diesel Extra comes in.
John Rasmussen, UK Retail Director, said: "We are delighted to be launching
Shell Diesel Extra at additional locations. It is a fantastic product that
continues the Shell tradition of delivering top quality, innovative fuels to
our customers. Shell Diesel Extra is a also the same price as our current
diesel so motorists will not pay a premium for a fuel that is designed to give
them better performance and lower emissions."
Q. What is Shell Diesel Extra?
A. Shell Diesel Extra is a new Diesel fuel with an exclusive
formulation, which is designed to help improve your engine's performance,
protect it and enable your vehicle to run more efficiently. The same team of
Shell technicians who develop fuels for the Ferrari Formula One cars and have
brought Shell Optimax to the UK motorist have created Shell Diesel Extra, which
is also exclusive to Shell.
Q: Can I safely mix Shell Diesel Extra with other grades of fuel?
A: Yes. Shell Diesel Extra can be mixed with all other Diesel fuels
without causing any damage to your engine. However the full benefits of Shell
Diesel Extra will not be achieved if mixed with other Diesel fuels. To achieve
the greatest benefit, refuel with Shell Diesel Extra every time.
Q. Can newer Diesel vehicles use Shell Diesel Extra?
A. Yes. The Shell Diesel Extra formulation contains a powerful detergent, which
is designed to help clean up and control the harmful fuel system deposits that
can build up on the precision fuel injection equipment found in modern diesel
cars. The fuel injection equipment found in modern diesel cars can perform
poorly if there is a build up of deposits on them. Shell Diesel Extra helps to
clean away these deposits, keeping the fuel injection system operating more
efficiently and helping to restore the engine's performance.
Q. Can older Diesel vehicles use Shell Diesel Extra?
A. Yes. Shell Diesel Extra is high in cetane. Cetane is an indication of the
fuel's readiness to ignite. A diesel fuel with a high cetane number can aid
combustion in older diesel vehicles, leading to the engine running more
smoothly with less noise and reduced emissions.
Q. Can heavy goods vehicles use Shell Diesel Extra?
A. Yes. Shell Diesel Extra's cleaning properties combined with its high cetane
number are designed to be beneficial for the heavy-duty engines found in HGVs.
Shell Diesel Extra helps to restore the engine's performance, reduce white
smoke and emissions, and fuel economy benefits may also be realised.
Q: Why does Shell feel the need to market this new fuel now?
A: Shell has conducted extensive research and has found that the diesel
motorists are demanding more from their vehicles and the fuel they buy. Shell
Diesel Extra has been developed specifically to meet the needs of these
customers. There is an increasing number of diesel motorists and they are very
important customers for Shell. Shell has recognised this and has now brought
the benefits of their fuel expertise to these customers.
Q. How does Shell Diesel Extra work?
A: Shell Diesel Extra is a unique formulation, which works to actively
clean up and control harmful fuel system deposits. This can help keep the
vehicle's precision fuel injection systems operating more efficiently. The high
cetane content of the additive aids more efficient combustion. The combination
of these effects can lead to more power, better fuel economy and lower
emissions in many vehicles.
Q: What evidence do you have that Shell Diesel Extra is better for a
vehicle's engine?
A: The exclusive formulation used to make Shell Diesel Extra has undergone
rigorous engine testing, proving the performance benefits of this diesel fuel.
We have extensive test results which show how removing and preventing the build
up of deposits in engines, helps maintain designed performance. But you'll only
reach its full potential with continued use. Shell Diesel Extra also contains
an anti-corrosion additive for further protection.
Q: How quickly will Shell Diesel Extra improve my vehicle's performance?
A: Shell Diesel Extra starts the process of removing deposits from the engine
from the first time you fill. As you use Shell Diesel Extra more, any deposits
on the engine's fuel injectors will be progressively reduced, improving your
engine's performance. Many older technology vehicles should notice the benefits
of the improved cetane quality from the first fill.
Q: What is cetane?
A: Cetane is an indication of the fuel's readiness to ignite. In
particular, many older diesel cars perform better when using a diesel fuel that
has a high cetane number. This is because it improves the combustion of the
diesel fuel, which can result in better starting, less noise, fewer emissions
and better fuel economy.
Q: Will Shell Diesel Extra affect my fuel economy?
A: Shell Diesel Extra helps to remove performance-sapping deposits from your
engine, which can lead to some fuel consumption benefits.
Q: Are you able to quantify the exact performance/fuel
economy/emissions/smoke/noise improvement that will be delivered?
A: We have extensive test results that show that all diesel vehicle
technologies (light and heavy duty; old and new) can derive a benefit from
Shell Diesel Extra. However, just how much an individual vehicle will benefit
depends upon many factors, including age, engine technology, driving style of
the driver, how well maintained it is, traffic and road conditions experienced,
and so on. In our experience, it is ill advised, and potentially misleading, to
make specific quantified claims.
Q: Is the launch of Diesel Extra simply a re-branding exercise of your
current diesel?
A: Diesel Extra is absolutely not just a re-branding exercise - our new
formulation offers a wide range of additional benefits when compared with Shell
Diesel or other regular diesel fuels.
Q: Won't the lumps of deposit that Shell Diesel Extra removes end up in my
engine and damage it?
A. No. Shell Diesel Extra does not chip deposits off the fuel injectors, it
dissolves them and washes them into the combustion chamber where they are
burned completely along with the fuel.
Q. Is Shell Diesel Extra available at all Shell Service Stations?
A. No. Initially it will only be available at selected service
stations - around 60% of our network, in Scotland , the north of England and
part of the South East of England. All service stations that stock Shell Diesel
Extra will advertise its availability clearly to our customers.
Q: Why is Shell Diesel Extra not available nation-wide?
A: Shell Diesel Extra is a unique fuel requiring specialist logistics
equipment to make it available for delivery; and this equipment is not as yet
in place nationally. We are, however, planning to extend distribution to
remaining parts of the UK as soon as it is possible to do so.
Q: How can I find out which sites will be selling Shell Diesel Extra?
A: You can call our customer service centre on 0800 731 8888 or view
the site availability listing on this website.
Q. How much does Shell Diesel Extra cost?
A. Shell Diesel Extra will be priced at the same competitive price as Shell
Diesel has been. You don't pay a higher price at the pump.
Q: Will I still be able to buy Shell Diesel from Shell?
A: Shell Diesel Extra will replace Shell Diesel at the pump in the areas
