Petrol or Diesel? The Great Debate

Petrol or Diesel? The two fuel types are so different that it can often be difficult to decide which option to take when choosing a new car. So this month we thought we’d take a look to determine the benefits for each and have 9 areas to consider when making your selection:




  • Fuel Economy

Data shows that for most models that have both a petrol and diesel variant, the fuel economy on the diesel is typically better than the fuel economy on its petrol counterpart. For example, the Mazda CX-3 Akari AWD Automatic Diesel has an official combined fuel economy of 5.1 litres/ 100km’s, whereas it’s petrol version reflects a higher figure of 6.7 litres/100km’s.


  • Purchase price

Typically speaking (although not necessarily always the case), a diesel vehicle will have a more expensive purchase price than its petrol equivalent. However, extra costs incurred by the purchase price can be saved through the better fuel economy achieved through the diesel vehicle, so check with a ProNovate Consultant to review the whole of life cost on each option.


  • Environment

Diesel fuel is a ‘dirtier’ fuel than petrol, and can emit large amounts of nitrogen compounds. However, diesel vehicles can emit lower amounts of carbon monoxide, hydrocarbons and carbon dioxide than petrol does. In addition, diesel fuel vehicles can achieve greater distances than traditional petrol engines and require less refuelling. When purchasing a new vehicle, check the carbon emissions with the manufacturer, as well as the Green Star Rating. If you are not sure, simply ask a ProNovate Consultant who would be happy to assist.


  • Resale

An important factor when choosing the right car is its future resale ability. Check whether the vehicle you are considering and a diesel or petrol variant, and speak with a ProNovate Consultant to establish which has the better resale ability.


  • Power

One of the key reasons that influences a person’s choice on a diesel or petrol vehicle, is the power that each option provides. Typically speaking, the diesel vehicle will offer more ‘torque’, whereas the petrol version will offer more ‘kilowatts’. As a result, diesel vehicles will usually have a much better towing capacity however petrol vehicles will be ‘zippier’ from 0-100.


  • Noise

There are many things to look out for when test driving a vehicle, but one thing to take note of is the noise in the cabin, particularly for diesel vehicles which can be louder than petrol variants.


  • Distance travelled

Diesel engines can be known to last a lot longer than petrol engines, which is why people who tend travel greater distances opt for diesel variants. Diesel drivers in such situations will not need to fill up as often, and their vehicle’s resale will not be hindered the same way that a petrol vehicle with a high odometer reading.


  • Refuelling

Diesel fuel can be quite dirty, and many people are known to wear gloves while they fill up, so this should be considered especially if you have a vehicle with a light interior and diesel can be transferred from your hands to the interior trim.


  • Pump price

An important aspect to consider is the difference in pump prices when refuelling your petrol or diesel vehicle. According to the Australian Institute of Petroleum, the average retail price on petrol for the 2015 Financial Year was 136.50 cents per litre, whereas the average retail price for diesel was 142.10 cents per litre.
