- The main advantage of LPG is the price. A litre of
LPG costs less than half the price of a litre of petrol.
|
- LPG does not contain or require any additives to improve
combustion or increase the octane rating of the fuel such as lead or lead
substitutes. LPG has an octane rating of over 106 which is much higher than that of
4star petrol at 98.
|
|
- The environmental advantages of LPG for marine use are
indisputable.
|
- Exhaust fumes and smoke are practically eliminated and noxious
gases are nearly eliminated as a result of the improved combustion of LPG. This is
in stark contrast to petrol, especially at engine start up.
|
- The absence of petrol acids and carbon deposits in LPG
combustion mean less wear and tear on the engine as engine
oil is not diluted and polluted with unburnt petrol and carbon particles. Oil
retains its' protective power much longer and needs to be changed less frequently.
|
- Petrol engines often flood when starting from cold. LPG
does not suffer from this problem.
|
- LPG is stored in liquid form in a built in tank(s). It is
vaporised just before entering the engine thus ensuring clean carbon free combustion.
|
|
- Spillage of fuel is impossible, engine noise is lower and
performance is comparable to petrol.
|
- The petrol fuel system is still retained therefore if
both petrol and LPG fuel
tanks are filled the cruising range is greatly increased.
