Great diesel myth: They DON'T save you money and petrol models 'are more economical for most makes of car'

Can take up to 14 years before diesel cars save the average driver money
Fuel can be almost 6p a litre more expensive than unleaded petrol
Findings come as diesels make up over half of new car market for first time

Diesel cars’ reputation for saving drivers money has been shattered by research showing they are often more expensive than petrol models.
It concludes that ‘diesels are no longer the default option for frugal motoring’.
While diesel engines may deliver more miles per gallon, it can take up to 14 years before they save the average driver any money.
This is because of the higher cost of diesel cars and of the fuel, which can be almost 6p a litre more expensive than unleaded petrol.
A report today by the consumer watchdog Which? says: ‘With drivers having to pay a premium for a diesel car – typically ￡1,000 to ￡2,000 more on a new car – our tests reveal it could take up to 14 years to recoup the up-front costs in fuel savings.
‘Lower pump prices for petrol and advances in petrol-engine efficiency mean petrol cars now often provide better value for money.’
Ironically, the findings come as diesels make up more than half of the new car market for the first time.
Which? compared similar-spec petrol and diesel versions of six popular cars – the Ford Fiesta, Vauxhall Astra, Volkswagen Tiguan, VW Sharan, BMW 5 Series and Peugeot 308 SW.
It calculated the annual fuel bill for each based on an average mileage of 10,672, and concluded: ‘In four out of our six examples, the petrol engine was the best choice for a driver covering 10,000 miles (16,000 km) a year.

Diesels often seem cheaper
b e c a u s e t h e b u y e r i s
hypnotised by the apparently low
cost of fuel instead of looking at the
entire cost of ownership, including
road taxes, increased servicing costs
and the cost of an expensive engine
rebuild that grows ever more likely
with every passing kilometre.
There are a few things you should
know about diesels:
1) Diesels cost more to buy. In
almost every case, new vehicles with
diesel engines cost significantly more
than the petrol equivalent.
Recently, carbuyers have developed
an unhealthy attraction to
diesels for fuel economy reasons,
especially European diesels. You
should be aware that, however much
you may save in fuel, European cars
fitted with diesels have a shocking
track record for reliability, and when
they break, they break your bank
account as well.
2) Diesels are generally noisier
than petrol engines, although you
may not notice this when you’re inside
the car, because diesel-powered
cars are often well soundproofed.
3) Diesel engines generally cost
much more to service & repair
than petrol engines. Diesel engines
need to be far stronger than petrol
engines. This additional strength
translates into additional expense
at fix-up time.
4) Diesel is often a lot less per
litre than petrol, but diesel-powered
vehicles must pay road tax in many
countries, which drastically raises
the true cost of the fuel.
5) Diesels may not be much
more economical for smaller vehicles.
Various tests comparing the
running costs of a petrol-powered
small car versus a diesel-powered
small car have concluded that the
average driver would take several
years at least, merely to get back the
extra cost of the diesel engine.
Diesels aren’t all bad: there are
two groups that do well from owning
diesels: owners of new commercial
vehicles and owners of large
offroad vehicles. Why?
New commercial vehicles are
often covering huge distances and
their owners are primarily concerned
with keeping running costs
as low as possible. Because a new
vehicle is under warranty, fuel and
servicing are likely to be the biggest
costs that commercial owners face.
Of these costs, fuel is by far the
biggest. If they’re doing big mileages,
a well-serviced new diesel can
be significantly cheaper to operate,
both in terms of fuel costs alone and
in terms of overall costs of ownership.
Because the vehicle will probably
be sold long before the engine
needs rebuilding, new owners don’t
care about the cost of diesel engine
repair. It’s the next guy’s problem.
Lastly, because the warranty will
require that the vehicle is regularly
serviced, the engine is less likely to
give trouble for its first owner.
It’s the person who buys the ageing
diesel vehicle off the commercial
operator who may be a loser – it’s
far more likely to require expensive
repairs & far less likely to have a
decent guarantee.
Owners of large offroaders with
proven engines such as those fitted
to the early Nissan Patrols and
Toyota Landcruisers are also likely
winners.
There’s a rough rule of thumb
with automotive diesels that the
larger the engine, the more likely it is
to be reliable, and vice versa. Older
Nissan Patrol and Toyota Landcruiser
engines have been known to do
500,000km without major repairs.
Also, there are many rural areas
where you simply can’t buy petrol
because there are no petrol stations.
Most farmers, by comparison, have
easy access to diesel.
However, unless you’re buying
new or buying a vehicle with
a proven service history, you don’t
know what the inside of the engine
is like. One thing that everyone
agrees on is that diesels are often
hellishly expensive to fix when they
do go wrong. So, there’s a general
rule that if you don’t know a diesel’s
history, you should avoid it altogether,
unless a diesel mechanic tells you
otherwise.
The bad news
You probably think that modern
diesels are better than earlier models
but you may be wrong. Although
many improvements have been
made over the years, big, reliable,
chugging diesels are rapidly going
the way of the dinosaur. The
ever-growing need for better fuel
economy, less pollution and greater
performance has meant that diesel
engines have been pushed beyond
their limits by over-eager vehicle
manufacturers.

Traditional diesel engines were
heavily built and rarely worked very
hard. Because they rarely worked
very hard, the engine lasted a long
time.
By comparison, most modern
diesels have turbochargers – giant
air pumps – pushing pressurised air
through them to make the engine
work at least a quarter harder. As
the engine works at least a quarter
harder, so the engine parts and cooling
system have to work at least a
quarter harder. Some of this extra
strain can be taken up with skilful
engine designs and higher quality
parts, but there’s a limit to this.
The latest generation of diesel
engines, termed common-rail diesels,
are the most efficient diesel engines
ever made, and when fitted to a
car offer good levels of power and
acceleration comparable to petrol
engines.
However, many turbocharged
common-rail diesel engines work
harder than any other diesels in
history. No matter how solidly they
are made, we do not believe that
they will last as long as their lesshardworking
cousins of old.
France is the world centre for
small diesel engines. Diesels account
for most of the new cars sold in
France and in Europe generally.
There is already plenty of evidence
of problems with the new
generation of European common
rail diesel engines, even when relatively
new. However, there are far
worse problems down the track,
after the vehicles leave warranty.
European diesel engines (like their
petrol siblings) are designed to
be used in one vehicle for a fixed
period of time and then disposed
of. They are computer controlled
and everything from the high tech
fuel pumps to the exhaust system
is designed to work together as one
whole unit. Without the computer
and the sensors in the exhaust pipe,
the diesel will not run properly.
The European carmakers know
this of course – in five or ten years’
time when their diesel becomes
uneconomic to fix or will no longer
pass emissions checks, they’ll be
waiting around to sell you a whole
new vehicle. The rest of the car will
probably be junk.
Peugeot diesels use a silicon
carbide honeycomb filter that absorbs
pollution, then every 500km
or so the filter system oxidizes the
absorbed pollutants by injecting a
small amount of fuel and a rareearth-derived
additive called Eolys
to superheat the exhaust and burn
off the soot left behind by burning
diesel.
Very clever no doubt, and we believe
Peugeot’s claim that the system
eliminates 95% of pollution. When
new. However, given Peugeot’s woeful
reputation for reliability even
with existing technology, hands up
everyone who thinks this system
will still be working reliably and
economically in ten years’ time?
Thought not.
Compare this to the modern
Japanese petrol engine: it’s worth
remembering that the basic Toyota
Corolla petrol engine is not all that
different to the models that they
were making twenty years ago;
it’s just somewhat more complex
and somewhat more efficient. It’s
proven, durable technology that is
cheap to buy, cheap to service, cheap
to fix, and if the car is too old to
make engine repair economic, you
can get a good, cheap petrol engine
from just about any wrecker.
What about Japanese diesel
engines? The older, smaller diesel
engines by Mazda & Toyota were
fairly dreadful. Nissan has always
been a market leader, until recently,
when some new high tech diesels
started giving grief at a young age.
Ditto Isuzu.
New European diesels require
a very clean type of diesel fuel, but
this new diesel fuel often wrecks
the diesel pump on older Japanese
models.
Outside of Europe, sales of diesel
vehicles were expected to fall,
but the opposite happened as fuel
prices rose.
We’d advise you to avoid diesels
altogether unless your needs can
only really be met by having a diesel
engine. If you must have a diesel, buy
new or with caution, perhaps great
caution, and for God’s sake have it
checked out by a diesel mechanic
before you pay over any money.
