About Diesel

Standard diesel fuel for compression-ignition engines. Popular for trucks, SUVs, and vehicles requiring high torque and fuel efficiency for long-distance driving.

Suitable for: Diesel vehicles including trucks, 4WDs, commercial vehicles, and diesel passenger cars

Complete Guide to Diesel in Australia

Overview

Diesel fuel powers a significant portion of Australia's vehicle fleet, from the Toyota HiLux and Ford Ranger (the country's two best-selling vehicles) to heavy commercial trucks and agricultural machinery. Unlike petrol engines that use spark ignition, diesel engines compress air until it heats enough to ignite the fuel spontaneously, producing more torque per litre and better fuel economy. Australian diesel meets the Euro 5 standard with a maximum sulphur content of 10 parts per million.

Who Should Use Diesel?

Diesel is the fuel of choice for drivers who cover long distances, tow trailers or caravans, or need a vehicle for commercial or off-road use. Popular diesel vehicles in Australia include the Toyota HiLux, Ford Ranger, Mitsubishi Triton, Toyota LandCruiser, Mazda BT-50, and Isuzu D-Max. Many SUVs like the Toyota Prado, Hyundai Santa Fe, and Kia Sorento also offer diesel variants. If you drive fewer than 15,000 kilometres per year mostly in urban areas, a petrol vehicle may be more cost-effective after factoring in higher diesel fuel prices and servicing costs.

Buying Tips for Australian Motorists

Diesel pricing in Australia behaves differently from petrol. While ULP in east coast cities follows distinct weekly or fortnightly cycles, diesel prices tend to be more stable with smaller fluctuations. However, diesel is often 10 to 20 cents per litre more expensive than ULP due to higher refining costs and stronger global demand (diesel is used for shipping, mining, and freight worldwide). Regional and rural areas typically see less price variation for diesel than for petrol, though prices increase with distance from capital cities due to transport costs.

Fuel Efficiency and Economy

Diesel engines are inherently more thermally efficient than petrol engines, typically achieving 20 to 35 percent better fuel economy. A diesel Toyota HiLux averages around 7.0L/100km on the highway versus 8.5L/100km for the petrol variant. For long-distance touring or towing, the efficiency advantage is even more pronounced. Modern common-rail diesel engines with turbocharging deliver strong low-end torque, making them ideal for hauling heavy loads up hills and towing boats or caravans.

Frequently Asked Questions About Diesel

What happens if I accidentally put petrol in a diesel car?

Do not start the engine. Petrol in a diesel engine can cause catastrophic damage to the fuel pump, injectors, and combustion system because petrol does not provide the lubrication that diesel fuel systems require. If you have not started the engine, a mechanic can drain the tank at a cost of $200 to $500. If the engine has been run, repair costs can exceed $5,000. Call roadside assistance immediately.

Is premium diesel worth the extra cost?

Premium diesel contains cleaning additives, cetane boosters, and anti-foaming agents. For newer vehicles with common-rail injection systems and diesel particulate filters (DPF), using premium diesel every third or fourth tank can help keep injectors clean and assist DPF regeneration. For older diesel vehicles without modern emission controls, the benefits are minimal and standard diesel is sufficient.

Why is diesel more expensive than petrol in Australia?

Diesel costs more to refine than petrol and faces strong global demand from commercial transport, mining, and shipping industries. Australia also imports a significant portion of its refined diesel, exposing prices to international market fluctuations and shipping costs. Unlike petrol, diesel does not experience the same deep discounting during price cycle troughs in Australian cities.

Do diesel cars need more maintenance than petrol cars?

Modern diesel vehicles require specific maintenance including diesel particulate filter (DPF) care, AdBlue top-ups for Euro 6 vehicles, and more frequent fuel filter replacements. Oil change intervals may also be shorter. However, diesel engines are typically built more robustly and can last 300,000 to 500,000 kilometres with proper maintenance, often outlasting their petrol equivalents.
