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
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.
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.
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.
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.
