Is a mixture of butane and propane.

Composition and characteristics of LPG for automotive use are regulated since 1993 by the European Norm EN 589. Thus its quality is constant and controlled.

LPG is stored, transported and supplied in liquid phase at ambient temperature and low pressure (5-10 bars), so high energetic density is available in reduced  volumes.

Which vehicles can use LPG as fuel ?

There are no restrictions from a technical point of view, so any vehicle equipped with an adequate engine could use it.

Nevertheless, the spanish tax system makes its use economically attractive only for public service vehicles like:

-	Taxis
-	Buses
-	Urban solid waste trucks
-	Lift forks
-	Other public service fleets (mail, ambulances, police, fire protection, delivery, etc.)

In other European countries its use is normal in private vehicles. This is expected to be possible in Spain in the near future.

LPG is the ideal energy for automotive use

The automotive use of LPG has technical, economical and specially environmental advantages:

Technical Advantages

An homogeneous and controlled mixture properly distributed in the cylinders produces a full an cleaner combustion. Longer lasting engine life.

Cheaper maintenance due to a lower number of breakdowns and lesser oil changes (no carbon residues)

Silent and vibration-free.

Service stations can be placed anywhere. Specifically, there is a wide network of LPG stations in Spain ensuring the adequate supply for LPG vehicles.

Minimum filling time.

Vehicles are technologically and commercially developed with reliability, performance and guarantees similar to the diesel powered ones:

For small and medium cars a gasoline engine requires a minor adaptation to be transformed into an LPG engine allowing the use of both carburants which provides double autonomy.

Buses and trucks are directly manufactured for the LPG use and are fully guaranteed.

Environmental advantages

Reduction of the regulated emissions (NO_x, CO, HC and particles) well below the levels accepted by the most demanding norms.

Reduction of the non regulated emissions like CO₂ (green house effect) aldehydes and aromatics (cancer agent substances).

No sulphur, no lead content.

Reduce odors, smoke and engine vibrations to minimum levels

Significant noise reduction.

Economical advantages

For small and medium cars (taxis, ambulances, mail, etc.) and lift forks represents an important saving (lower purchase cost, lower maintenance cost and lower fuel costs).

For heavy vehicles (buses and trucks) Repsol Gas makes a taylor-made offer for every single customer, depending on the number of vehicles purchased (current and future) assuring the total cost of the vehicle being equivalent to those of a diesel one during the life of the vehicle.

Reduction of other city costs (health, city cleaning, etc.) due to the use of an environment friendly fuel.

LPG Automotive market. World and Spain

LPG automotive world markets started to develop in the seventies basically for economical, energy diversification and environmental reasons. Today there are some 4 millions LPG vehicles in the world filling their tanks in about 23.000 service stations.

In Spain, the market started also in the seventies thanks to our commercial and technological efforts. There are now up to 10.000 LPG taxi cabs, being a consolidated and competitive product using a 40 station service network, distributed all over Spain.

We have also pushed the use of LPG in urban buses and garbage collecting trucks. There are now 57 LPG buses in Valladolid and 6 in Vigo, as well as 3 urban solid waste trucks in Madrid and Barcelona.
