What is LPG and is it cheaper than petrol?

As petrol and diesel prices remain high, putting pressure on families’ budgets across the nation, many have started looking for cheaper alternatives.

One of the options available is LPG, which can be used in a variety of ways, ranging from fueling cars to heating homes.

Here’s everything we know about what LPG is, how it compares to petrol, and its environmental implications.

What is LPG?

LPG, sometimes referred to as LP gas, stands for liquefied petroleum gas.

It is a type of fuel gas that is made up of a flammable combination of hydrocarbon gases, like butane and propane.

Liquefied petroleum gas is made by refining petroleum, that can also be defined as “wet” natural gas, and is mostly derived from fossil fuel sources.

Many countries use it to cook their food and heat homes in rural areas where there isn’t a direct connection to piped natural gas. Perhaps the most common use of it is as motor fuel.

Is LPG cheaper than petrol?

As it stands, LPG has less tax duty and costs about half the price of petrol.

LPG has a lower energy density per litre compared to petrol, so LPG cars need more fuel to go the same distance as petrol vehicles.

However, the significant tax duty difference still makes it a more affordable fuel option.

One thing to keep in mind is that drivers who don’t already have an LPG converter in their car will have to invest in one before they can switch from petrol.

Those who have a diesel vehicle won’t be able to install a converter. So, LPG isn’t an option for these drivers.

How does LPG impact the environment?

While LPG still releases greenhouse gases that have negative environmental consequences, cars that use LPG generate less carbon-dioxide and nitrogen-oxide emissions than petrol and diesel cars.

According to Liquid Gas UK, LPG produces 90 per cent less carbon monoxide and 50 per cent less smog than natural gas. It also evaporates on its own, eliminating environmental risks if there are spillages.

As it burns relatively cleanly, it doesn’t cause any black smoke from the exhaust that is often seen in older diesel cars.
