LPG is a fuel obtained by processing petroleum, while CNG is compressed natural gas. Both gaseous substances can be used as automotive fuels. However, there are differences between them related to their properties and combustion technology.
Fuel for conscious drivers
Autogas means pure savings, longer car range and care for the natural environment. This is a solution for conscious drivers who know what they want and appreciate the value of the investment. If you want to drive economically, comfortably and ecologically – choose an LPG system. Autogas is smart!
With autogas You can go further
It’s easy to calculate that after refueling with LPG for the same amount instead of petrol, you will always cover more kilometers. Each car equipped with a gas system can be powered by a different fuel – petrol, diesel or hybrid. Thanks to this, you can cover a much longer distance without the need for additional refueling. Just in case, you always have a second fuel tank.
Autogas always pays off
Autogas is definitely cheaper than petrol or diesel – that’s a fact. It simply pays off, regardless of whether the car covers higher or lower mileage. If you travel 2,000 kilometers on average a month, you save a lot of money by filling up your gas tank. The cost of installing an autogas installation can be reimbursed even after driving 10,000 kilometers. Of course, the more you drive and the more fuel your car’s engine consumes, the more you save on refueling. Return on investment in a gas installation is only a matter of time.

Longer Engine Life
Autogas burns cleaner than gasoline, which may contribute to less wear and deposition of pollutants in the engine. Ignition is smoother and more efficient, and the protective layer of engine oil is not washed away from the cylinder walls. That’s why autogas-powered cars often have a longer engine life.
Safety
Autogas systems are designed with safety in mind. LPG/CNG tanks are durable and have security measures that minimize the risk of fuel leakage. These are precisely refined systems that meet strict homologation standards – there are no exceptions to them. The production technology takes into account the highest level of security, much higher than that applicable to the petrol fuel system.
Performance and Power
A well-installed autogas system does not reduce the engine’s power, and can even increase it! That’s why users of cars such as the Ford Mustang 5.0 V8 or the 6-liter Hummer also install gas systems.
Environmental aspect
Autogas is cleaner than petrol or diesel and emits fewer harmful substances, such as carbon dioxide (CO2), nitrogen oxides (NOx) and particulate matter. As a result, cars powered by autogas have a lower negative impact on the environment.
What is LPG? How is it produced?
LPG (Liquid Petroleum Gas) is a natural product obtained as a result of the extraction and refining of crude oil and natural gas extraction. This substance is a mixture of propane, butane and other gases. Autogas is flammable but non-toxic. When subjected to slight pressure (2-8 bar), it becomes a liquid. This matters because the transition to a liquid state reduces the volume of LPG by approximately 250 times. This allows you to store more gas in less space. Gas fuel is odorless, but for safety reasons, a characteristic fragrance is added to the mixture.

Availability
Product of petroleum refining. It consists mainly of propane (C3H8) and butane (C4H10). It may also contain small amounts of other ingredients such as ethane or pentane.
Natural fuel extracted from gas fields. It consists mainly of methane (CH4) and is the main component of natural gas.
It is a liquefied gas, which means it takes up less space in the tank compared to a gas with the same amount of energy.
It is a compressed gas and takes up more space than LPG with the same amount of energy. It must be stored under high pressure in cylindrical tanks.
Widely available at gas stations in many countries. There is extensive infrastructure for the supply and distribution of LPG.
CNG fueling stations are more concentrated in certain regions or cities.
