JC Select Nulon Additives

Cheap insurance for your diesel vehicle's most expensive parts

Modern diesel engines are engineering marvels, but their DPFs and injectors are vulnerable. A quarterly additive program from Nulon costs a fraction of the cost of a new engine.

DPF repairs and injector replacements are among the most expensive diesel maintenance jobs around, often running into thousands of dollars. What many diesel owners don't realise is that standard Australian fuel, and even premium diesel, is missing the key additives needed to properly protect these components over the long term. That gap quietly accelerates wear, and by the time a warning light appears, the damage is already done.

Nulon's diesel additive range is designed to fill exactly that gap. The Diesel Fuel System Extreme Clean (DEC) works inside the fuel system to prevent the deposit build-up that clogs injectors and disrupts fuel delivery, keeping your injectors flowing cleanly and precisely as they should. The Diesel Turbo Cleaner (PDTC) uses a fuel-born catalyst that survives combustion and flows through the exhaust system, actively removing the soot deposits that cause turbos to stick, DPFs to block, and EGR valves to fail. Together, used just four times a year, they give your diesel's most vulnerable and expensive components a genuine fighting chance. Available online and at your local Auto One store.
