Converting a car to LPG (Liquified Petroleum Gas) can be worthwhile, primarily due to significant fuel cost savings, but it's essential to consider the upfront costs and other factors. While LPG is generally cheaper than petrol, the conversion can be expensive, and the long-term financial benefits depend on factors like your annual mileage, driving habits, and the specific vehicle. Converting a car to run on LPG (liquefied petroleum gas) can be worthwhile for some drivers, but it depends on several factors. Below is a breakdown of the key considerations to help you decide:
Advantages of LPG Conversion
Lower Fuel Costs
LPG is typically cheaper than petrol or diesel (often by 30-50% in many regions). For drivers who cover high annual mileage (e.g., 15,000+ km), the savings on fuel can quickly offset the upfront conversion cost.
Reduced Engine Wear
LPG burns cleaner than petrol or diesel, producing fewer carbon deposits. This can extend engine life and reduce maintenance needs (e.g., less frequent oil changes or spark plug replacements).
Environmental Benefits
LPG emits lower levels of harmful pollutants like CO₂, nitrogen oxides (NOₓ), and particulate matter compared to diesel. It may also qualify for lower emissions-related taxes or congestion charge exemptions in some cities.
Dual-Fuel Flexibility
Most conversions retain the ability to switch back to petrol/diesel, providing flexibility if LPG is unavailable. This is useful for long trips in areas with limited LPG refueling stations.
Disadvantages of LPG Conversion
Upfront Conversion Cost
Installing an LPG system (including a tank, injectors, and control unit) can cost $1,500–$4,000, depending on the vehicle and kit quality. This is a significant initial investment, and it may take years to recoup for low-mileage drivers.
Reduced Boot Space
The LPG tank (usually mounted in the boot) takes up storage space, which can be a drawback for families or those needing cargo room.
Limited Refueling Infrastructure
While LPG stations are common in some countries (e.g., parts of Europe, Australia), they are less widespread in others. This can be inconvenient for rural or remote drivers.
Slightly Lower Fuel Efficiency
LPG has a lower energy density than petrol, meaning you’ll get fewer kilometers per liter (typically 10–15% less). This means more frequent refueling, even if each fill-up is cheaper.
Potential Impact on Vehicle Value
Modified vehicles may have lower resale value, as some buyers are wary of non-factory fuel systems. Ensuring the conversion is certified by a reputable authority can mitigate this risk.
