Used diesel engine vehicles form a significant part of the African automotive market. An increasing number of people in Africa are considering purchasing a used diesel engine vehicle. Diesel engines are renowned for their durability, fuel efficiency, and impressive torque compared to their gasoline counterparts.
“Despite the growing push towards electrification and increasingly stringent emissions regulations, diesel cars still hold a significant position in the used car market,” says Davide Orlandi – Sales and Marketing Director at International Automotive Parts Srl. He further highlighted, “While uncertainties about the future of this technology may raise doubts, purchasing a used diesel car can still be a beneficial choice for various reasons.”
Their fuel efficiency and perceived durability make them attractive, particularly in regions with unreliable electricity grids. “Although electric and hybrid vehicles are gaining popularity, diesel engines remain competitive. They offer a long range and quick refueling times, crucial factors for many drivers,” asserts Orlandi.
Additionally, purchasing a used vehicle, especially one powered by a diesel engine, requires careful consideration of several key factors to ensure a reliable and cost-effective investment. These factors include:
1. Engine Condition and Longevity
The engine is the heart of any vehicle, and it’s crucial to ensure that the engine of the used diesel vehicle you’re considering is in good condition. You should check for any visible signs of wear and tear, such as leaks, cracks or corrosion. It’s also essential to check the engine’s vital components, such as the turbocharger, fuel injectors and cylinder walls. “Another important factor to consider is the longevity of modern Euro 6 diesel engines, which have an average lifespan of around 10 years,” Says Orlandi.
Besides, a professional mechanic can help you determine the engine’s condition and identify any potential issues as well as advice you on longevity. A lower mileage vehicle is generally preferable, but a well-maintained higher mileage vehicle can still be a good investment.
2. Emission System
Diesel engines emit nitrogen oxides and particulate matter, which can be harmful to the environment and human health. Therefore, diesel vehicles are subject to strict emission standards. Before purchasing a used diesel engine vehicle, you should check its emission system to ensure that it complies with the relevant regulations. You should also consider the vehicle’s emission history, which can indicate potential issues with the emission system.
3. Fuel Efficiency and Cost of Ownership
One of the primary benefits of diesel engines is their better fuel efficiency compared to gasoline engines. However, the fuel efficiency can vary between different diesel engine vehicles. You should consider the vehicle’s fuel efficiency ratings and compare them to other similar models. Additionally, you should consider your driving habits and needs to determine the most fuel-efficient option for you.
“Diesel cars are particularly suitable for those who drive at least 20,000-25,000 kilometers per year, especially on highways. Their superior thermodynamic efficiency ensures optimal performance, smooth driving, and significantly lower fuel consumption compared to other engine types. This translates into substantial fuel savings over the long term,” elaborates Orlandi.
“Additionally, the widespread availability of diesel fuel stations provides a further advantage over the still-under-development electric charging infrastructure,” he adds.
Besides, fuel prices fluctuate, and knowing the potential impact on your running costs is vital. Beyond fuel, factor in the cost of regular maintenance, including oil changes, filter replacements and potential repairs. Diesel engines often require specialized lubricants and filters, which can be slightly expensive than those for petrol engines.
4. Maintenance History
Regular maintenance is crucial for the longevity and performance of diesel engines. Therefore, it’s essential to check the vehicle’s maintenance history before making a purchase. A well-maintained diesel engine vehicle can last for hundreds of thousands of kilometers, while a poorly maintained one can have significant issues. You should also look for evidence of regular oil changes, filter replacements and other routine maintenance tasks.
5. Noise and Vibration
Diesel engines are known for their distinctive noise and vibration, which can be more pronounced than in gasoline engines. However, excessive noise and vibration can indicate potential issues with the engine or other components. You should test drive the vehicle and pay attention to any unusual noises or vibrations, which could indicate worn-out components or other problems.
6. Price and Value
Diesel engine vehicles can be more expensive than their gasoline counterparts, but they also offer better fuel efficiency and longer engine life. Therefore, it’s essential to consider the vehicle’s price and value before making a purchase. You should compare the price to similar models and consider the vehicle’s long-term costs, such as fuel and maintenance expenses.
7. Availability of Parts and Mechanics
Before committing to a purchase, research the availability of spare parts and qualified mechanics in your area. Some diesel engines are more common and easier to service than others. Ensure that you can readily source replacement parts and find a competent mechanic who is familiar with the specific engine model. This is particularly important if you plan to use the vehicle in remote areas.
8. Warranty and Insurance
Warranty and insurance are essential considerations when purchasing a used diesel engine vehicle. You should check whether the vehicle is still under warranty and what it covers. Additionally, you should consider the cost and availability of insurance for diesel engines, which can be more expensive than for gasoline engines.
9. Legal and Regulatory Considerations
Diesel engines are subject to strict regulations, and it’s essential to ensure that the vehicle complies with the relevant laws and regulations. You should check whether the vehicle has any outstanding recalls or safety issues and whether it meets the relevant emission standards. Additionally, you should consider the vehicle’s registration and insurance requirements in your state or province.
Carefully Evaluate
Purchasing a used diesel engine vehicle can be an excellent investment, given the numerous benefits of diesel engines as discussed above. As he concludes, Orlandi remarks, “Choosing a used diesel car can be a strategic and advantageous decision, provided that certain essential factors are carefully evaluated: the vehicle’s age, the condition of the diesel particulate filter, and compliance with local emissions regulations.”
Nevertheless, to ensure a reliable and cost-effective choice, consider consulting a trusted mechanic for expert advice and a professional inspection to make an informed decision.
