LPG Guide

Liquefied Petroleum Gas (LPG) as an alternative automotive fuel

Autogas is the term generally used for Liquefied Petroleum Gas (LPG), when it is used for the propulsion of road vehicles.

It is obtained as a by-product of the distillation of oil from crude oil and from "wet" North Sea gas. It is produced in large quantities, a surplus of approximately 4 million tonnes per annum is currently available from the North Sea . This surplus is forecast to increase over the next 20 years.

When it is pressurised it becomes a liquid and it is in this form that it is pumped into your tank. Compared to petrol, Autogas has a higher octane content (according to the RON method).

  • Super grade petrol 98
  • Lead free 95
  • LPG over 100

Background Info

For over 5 years, LPG-Cars has been trouble shooting petrol fuelled vehicles to run on dual fuel LPG now commonly known as Autogas. Many of our customers will remember the very early conversion equipment used on pre injection vehicles and the challenge to find a local supply of fuel!

With the development of modern fuel injected engines and complicated computer engine management systems it has been a challenge to develop compatible conversion equipment in line with the constantly stringent demands for improved vehicle emissions.

The challenge is met today with new direct gas injection systems incorporating advanced engine management software providing low emissions whilst maintaining optimum engine performance.

As with all developing markets, there has been a rapid growth in the number of companies and individuals offering LPG conversions, many of which have little or no formal training and offer no technical support or after sales service. Partly as a result of the lack of statutory regulation, the result has often been poorly or incorrectly installed conversion equipment that in some cases may not even be suitable for the vehicle converted.

In response to demand from a few dissatisfied customers, LPG-Cars is now offering a diagnostics and repair service on a variety of LPG systems in use in the UK today. LPG-Cars believe that many of the problems experienced by customers can be rectified, resulting in better running, satisfied customers and promoting a sustainable market.

A new workshop has been developed in Coventry, incorporating advanced LPG diagnostics equipment. Whilst proving invaluable for testing the performance of vehicles on completion of a conversion, finer tuning of the engine to reduce tail pipe emissions provides a clear indication of the advantages of using LPG as an automotive fuel.
