The prices of petrol and diesel are increasing constantly around the globe, and Australia is no exception. This presents LPG (liquid petroleum gas) cars as an excellent alternative to cars running on conventional fuel.
As of 2025, LPG costs about AU$1.119 per litre, while petrol costs AU$1.93 and diesel AU$1.95. Despite this affordability, less than 2% of Australian vehicles run on LPG, and it is about time to change that for good.
So, buying LPG cars could be an excellent alternative if you are also looking for an affordable transportation mode. But before that, make sure to read this comprehensive guide to the end to learn more about these cars.
What is an LPG Car, and How Is It Different From Conventional Cars?
LPG cars are vehicles that run on LPG instead of conventional fuels like petrol and diesel. This is the primary characteristic that sets these cars apart from most cars running on conventional fuel.
These cars use LPG, a mixture of butane and propane, which offers buyers an excellent alternative. In the battle of LPG cars vs. petrol cars, LPG stands out in terms of affordability and environmental impact.
It is also worth noting that you can convert your petrol car into an LPG car, but you can’t do the same with diesel cars. The logic here is that LPG burns the same way petrol does in your car, which is different from the mechanics of diesel engines.
Are LPG Cars Safe in 2025?
If you have even the slightest idea about LPG cars, you should know these cars have been around for quite some time now. The ignition process in these cars is quite similar to that of petrol cars. Just as petrol cars store fuel in the tank, the same goes for LPG cars, where you store the fuel in a thick steel tank.
In certain cases, you might have to deal with small leaks in the fuel tank of LPG cars after thorough vehicle inspections. But these leaks are generally quite small and don’t pose any significant danger. In fact, TNO carried out a test and concluded that LPG tanks are safer than petrol tanks in case of an accident.
In case of a fire, you have three times more time to escape an LPG car than a petrol car. This should be reason enough for you to consider the purchase of LPG gas vehicles over petrol, but more on that later.
Must-Have Features and Qualities in LPG Cars
Referring to a proper guide LPG cars and buying these vehicles can be an excellent choice for you. But before you finalise this decision, you must have a clear idea of the features to look for in these cars. So, here are some of the most important features and qualities you need to look for in an LPG car:
1. Fuel Efficiency
The first and foremost factor to consider is your car’s fuel efficiency. Just like conventional cars, several factors can influence the mileage of your LPG vehicle. These include driving habits, engine size, and the car’s weight. Be sure to take these into account when assessing fuel efficiency.
There is no denying that LPG burns faster than petrol, but it also costs less on a per-litre basis. The best thing you can do here is to get an LPG gas inspection and determine consumption in litres per kilometre. This is one of the most important things to check in an LPG car before buying one.
2. Dual Fuel Compatibility
The best thing about LPG cars is their compatibility with two fuels, LPG and regular petrol. This gives you the flexibility to shift between fuel systems based on your needs and preferences. This is a great choice for people commuting long distances, as these cars can run either fuel.
This makes it very important that you only buy an LPG car that comes with dual fuel compatibility. This is not just great for the overall convenience of driving a car but also enhances overall practicality. Most importantly, you can easily travel through areas with fewer LPG mobile car maintenance stations without any headache.
3. Fuel Tank Capacity
Fuel tank capacity is an important thing to consider when buying an LPG vehicle after a full car inspection. This is important since it directly affects the car’s total driving range. Getting a larger tank makes sense if you travel long distances.
However, this also means you will have to compromise on the car’s boot space. Hence, it is important for you to evaluate your unique needs and preferences to make the right choice.
4. Performance Check
Contrary to popular misconception, LPG cars are just as powerful as vehicles with a petrol engine. Of course, there is always room for some performance discrepancies, but this should not be a matter of concern.
While you take the LPG car out for the test drive, make sure you drive it through different terrains and roads. This should give you a much better idea of the car’s overall performance potential and help you make an informed choice.
Checklist for Buying an LPG Car in 2025
By now, you should understand the advantages and disadvantages of LPG cars. That said, it is now time to see the checklist for buying these cars. So, here are some of the most important things that you need to check:

This certification verifies that the LPG tank is in proper condition, and you can buy the car without any hesitation.
Final Thoughts
As petrol and diesel fuel prices continue to increase, LPG cars are excellent alternatives to these vehicles. You need not spend much on maintenance and mobile car servicing for these cars, which is quite beneficial in the long run.
It is all about evaluating the right relevant factors and information to make an informed choice here. This means you should check the car’s fuel tank capacity, performance potential, mileage, and, most importantly, the dual fuel compatibility of these vehicles. But before you finalise your decision, take a test drive, conduct proper car inspections Adelaide, and check LPG tank certification. This will help you make the right and informed choice to get the best deal.
