July 25 - 31, 2011

LPG (Liquefied Petroleum Gas) is in use worldwide in an estimated 16 million plus vehicles. Auto conversions to LPG are encouraged by the governments of the UK, Australia, and Turkey.

LPG has been in use in Pakistan since the 1970s in rickshaws, taxis, pickups and private cars. Domestic/commercial/industrial users for heating/cooking/other purposes also use LPG. LPG is an excellent fuel for gasoline engines for several reasons.

There are 16 million vehicles using LPG world wide. Only 2.2 million vehicles are using LPG in Turkey.

With the new Diesel-Dual-Fuel (DDF) technology, LPG is used in diesel engines, improving mileage, power & torque and greatly reducing toxic gases & carbon particulates in the emissions. Next generation car kits also allow LPG through a single conversion. LPG, being a liquid with low pressure, allows users to install larger capacity tanks due to lesser weight (up to 100 litres are already in use) which means far greater distances can be covered with one fill.

Engines on LPG last almost twice as long as those on petrol and CNG. LPG produces the lowest amount of CO, CO2, NO2 and green-house gases compared to other fuels - hence, it is most eco-friendly. LPG is gaining popularity as an alternative fuel in industry as well as specific power generation applications (as SNG).

LPG is more readily available around the world. It is a byproduct in the refining process or extracted from condensate at the wells of natural gas.

ADVANTAGES COMPARED TO OTHER FUELS

- It is actually better than petrol because it reaches the engine in pure gas form with improved combustion resulting in fewer knocking.

- With modern technology, there is very little discharge of carbon monoxide, and compared to petrol and diesel, the exhaust fumes contain less harmful substances.

- The life of the engine is extended as a result of the absence of acids and carbon deposits. One can safely state that engines on LPG last almost twice than that on petrol.

- Unlike diesel, one does not have to adjust their driving style. Cold starting is no problem. Engine performance is almost exactly the same as with petrol. There is no spilling when filling the tank and no possibility of theft or pilfering. Engine noise is low and one drives in a more environment-friendly way.

- LPG is a clean burning, high octane, environment friendly fuel. It generates no smoke or fumes and emits extremely low levels of carbon monoxide, hydrocarbons, and nitrogen oxides. It emits virtually no sulphur oxides and no particulate matter.

- LPG can be used in a way similar to diesel, with liquid sequential multi point fuel injection (MPFI). Experts also say that owing to the strength and integrity of the fuel tank, LPG is safer than petrol and is on par with diesel.

Hascol Petroleum Limited will market the LPG as an automotive fuel through its retail network and in this connection necessary license has been obtained from OGRA and LPG installation is in progress at Hascol retail outlets. HPL is geared up to implement international safety standards.

Hascol will be the first oil marketing company to launch LPG through its retail outlets.
