About Premium Diesel

Enhanced diesel fuel with additives for better performance, cleaner injectors, and improved cold-weather starting. Often includes cetane boosters for smoother combustion.

Suitable for: Modern diesel vehicles, European diesel cars, vehicles with DPF systems

Complete Guide to Premium Diesel in Australia

Overview

Premium diesel is an enhanced version of standard diesel fuel fortified with cetane boosters, detergent additives, anti-foam agents, and lubricity improvers. In Australia, major offerings include Shell V-Power Diesel, BP Ultimate Diesel, and Ampol Amplify Diesel. The higher cetane number (typically 51 to 55 compared to standard diesel's 46 to 51) provides smoother, more complete combustion with less noise and vibration.

Who Should Use Premium Diesel?

Premium diesel is most beneficial for modern common-rail diesel vehicles with diesel particulate filters (DPF) and selective catalytic reduction (SCR) systems. European diesel vehicles from BMW, Mercedes-Benz, Volkswagen, and Audi particularly benefit from the cleaner-burning properties. If your diesel vehicle regularly does short urban trips that prevent DPF regeneration, using premium diesel every third or fourth tank can help keep the DPF system functioning correctly.

Buying Tips for Australian Motorists

Premium diesel typically costs 5 to 10 cents per litre more than standard diesel. Not all stations stock premium diesel, so availability is more limited than standard diesel. For most drivers, using premium diesel every third or fourth fill is a cost-effective compromise that maintains injector cleanliness without the ongoing premium. For vehicles primarily doing highway driving, standard diesel is usually sufficient.

Fuel Efficiency and Economy

The higher cetane number in premium diesel can improve fuel efficiency by 1 to 2 percent through more complete combustion. The detergent additives help maintain optimal spray patterns from the injectors, preventing the gradual efficiency loss that dirty injectors cause. Over 50,000 kilometres of consistent use, the cumulative effect of cleaner injectors and better combustion can be meaningful for engine longevity and maintained fuel economy.

Frequently Asked Questions About Premium Diesel

Can I alternate between standard and premium diesel?

Yes, you can freely switch between standard and premium diesel without any issues. Many mechanics recommend using premium diesel every third or fourth tank as a cost-effective way to maintain injector cleanliness. The fuels are fully compatible and can be mixed in any proportion.

Will premium diesel help with DPF regeneration issues?

Premium diesel can assist with DPF maintenance because the more complete combustion produces less soot, reducing the frequency of regeneration cycles needed. However, if your DPF is already blocked, premium diesel alone will not fix it. Regular highway driving at sustained speeds remains the most effective way to trigger DPF regeneration.
