What Is LPG
LPG is produced during the normal petrol chemical
distilling process of crude oil and the letters LPG
stand for Liquefied Petroleum Gas, so in other words -
petrol gas - which is 100% octane as in 100% octane 5*
petrol 97/98 4* and 97 super unleaded. Any car can run on
high octane fuel without modification, problems arise
from cars designed to run on high octane being asked to
use regular unleaded, which is 94%. LPG is stored in a
liquid form because being 250x more dense than as a gas
it requires less space within the car. Many
manufacturers, including Renault, Citroen and Vauxhall
offer LP gas cars direct from the dealership as part of
the range. Other manufacturers such as Ford, Range
Rover and Chrysler may not have an LPG vehicle as part
of the range but will allow conversions to be carried
out after manufacture.
of the largest nations for LPG use in vehicles are Italy
and Japan, who are not oil producers. In the UK we
produce in excess of 4 million tonnes per year.
What are the Benefits
The benefits are:
- smoother, quieter, cleaner running for your car
- 30% extended engine life
- cleaner air for all
- half price fuel for you
- lower service costs
- extended cruising range. The ability to run on both petrol and gas.
- safety - allowing you to drive a larger/luxury car with inherent added
safety features and better crash protection qualities.
- as a business user you will be able to recoup some of the
conversion cost as a capital expense.
- added reliability - the RAC and AA will confirm that most breakdowns are
fuel related. On a rainy night having a second, fully
independent tank of fuel might give some comfort.
- possible reduced insurance premium
- possibility of running one larger/luxury car for all journeys and selling second
- resale value enhanced, especially on larger
engined or luxury cars where running costs put a lot of

Who Uses LPG
Worldwide millions of people have been
benefiting from converting their car to run on LPG and
now many car companies including Mitsubishi, Volkswagen
and Smart are offering duel fuel models, which has proved very popular with fleet
buyers looking to save on running costs. We are
currently converting cars direct from the factory for
Ford for the BP fleet.
In Europe, countries like Italy having nearly 1.5m but
also countries like Japan, where 90% of taxis use LPG
and Australia where on bigger vehicles it is extremely
popular and even in America, where petrol is currently
25% of the
cost in the UK, in certain clean states such as
California. In the UK high profile users including Royal
household, ministerial cars, local authorities, police
forces and the support service industry such as UPS and
Securicor. Also at the last budget the government
allocated a further £30m towards London black cab users
and fixed the price of LPG until 2008, but the main
private users of LPG are people who appreciate smoother,
quieter running, longer engine life, cheaper car
insurance and half price fuel as well as knowing that
you are doing your bit for the environment.

How Much Will I Save
Whatever you are spending on petrol will be halved on
gas if you take into consideration longer engine life
and longer engine peak performance. Also bear in mind
for the larger/luxury car sector LP gas is very much a
selling point, but should you feel that you are unable
to justify a premium at resale the conversion can be
fully removed and the car left in near original form and
the kit can be re-used on another vehicle, we can
reprogram. Also, you might qualify for cheaper car
insurance and with car taxation soon to be based on
emissions you might qualify for cheaper road tax and

we Convert Your Car
Within reason, all petrol engine vehicles can be converted with age and
mileage not being as important as condition. We
regularly convert high mileage modern and classic cars
with anything up to 200,000 miles.
If we are happy to do the job you will be happy with the
results. Over the years we have converted in
excess of 100 Jaguar/Daimler vehicles, dozens of Range
Rovers, Cherokee Jeeps, Chrysler Grand Voyagers, Ford
Mondeos and Galaxys. Please contact us and we will
be happy to inform you if your car is suitable.
For more information please see our Ford press release
on home page and editorials from Jaguar Enthusiast,
Jaguar Monthly, Jaguar World and Jaguar Drivers' Club
magazines. For more information please go to
Editorial page. More information on
Jaguars/Daimlers can be found on websites listed

Safety and Insurance
LPG has an excellent safety record and is industry
recognised as being safer than petrol. This is due to
the construction of the LPG tank being more robust and
on our system having 3 fuel safety shut off solenoids
and safety vent system which can open and close at a split second but will not
be open unless the engine is running. LPG converted cars
may affect your insurance premium and you may be able to
save up to 20% through LPG Sure who can be contacted
cars should not normally affect any other warranties in
force, but we offer in such cases a comprehensive
Olympic warranty which is included in the cost of the
for a quotation.
LPG is so much better for the environment, which is
becoming a major issue worldwide, that manufacturers
such as Ford, Vauxhall have endorsed LPG converted vehicles
by, not only running a number themselves, but also price
fixing LPG taxation until 2009. Various grants are
available to London black cab drivers and certain other
users but not currently private users, although some
cars can qualify for London Congestion Charging
Worldwide the number of cars is expanding at an alarming
rate. In the UK alone we have 24 million. With LP gas
being up to 75% cleaner on petrol and up to 90% cleaner
on diesel everyone will benefit from the number that
convert. The UK currently, on the DVLA register,
only has 150,000 LPG vehicles so it would be a long time
before the government would get any benefit from putting
the price of LPG up.
