Petrol vs diesel Engines…… the big debate resolved

Diesel is slowly but surely becoming a new trend as diesel-fueled cars are no longer what they used to be. Senior mechanic Khalifani Kyasanku Zion Auto Garage says that diesel engine cars are no longer ‘noisy or billow out plumes of smoke every time they pull off’. They are also not less powerful than petrol engine vehicles anymore.


A recent study showed that consumers are becoming more interested in diesel-powered vehicles because they go longer distances, have better resale value, and give you performance and towing capacity without sacrificing the joy of driving.

Diesel-fueled cars also tend to be more fuel efficient, both in city driving situations as well as on the long road. At the moment, diesel cars are more affordable than petrol. However, petrol still remains a firm favourite fuel choice for some people – that’s why most cars still run on petrol.

However, when deciding between a diesel or petrol car, the fuel efficiency and price of the car shouldn’t be the only factors. You should also think about the maintenance, size and type of vehicle and the depreciation value. Kyasanku advises that diesel vehicles have traditionally been more expensive to service. However, many modern diesel vehicles now have similar service intervals to petrol powered vehicles. Service intervals can vary however and depend on the manufacturer’s recommendation. Depreciation is a major factor when considering which fuel type to use. In particular, petrol models of large 4WD’s tend to depreciate more quickly than their diesel equivalents.

On a whole,  large cars and 4WD vehicles with high fuel consumption often will benefit from being diesel powered while smaller cars with petrol engines of around 1.6 litre (or less) capacity will generally be very fuel efficient. Therefore, if you’re thinking of buying a large SUV diesel is the better option, whereas petrol will be more appropriate for a smaller car with a smaller engine.
