AMSOIL All-in-one Diesel additive (XL)

AMSOIL Diesel Additive (Bigger 1.9L container)

Cleans the fuel system, boosts cetane levels, and ensures smooth flow even in winter use.

Quite possibly the best **diesel additive** on the market combines three key features into one: injector and pump cleaning and lubrication properties, ensures smooth fuel flow in freezing winter conditions, and increases cetane levels for smoother operation, better fuel efficiency, and maximum power output. This versatile diesel additive is designed for use with all diesel fuels, including biodiesel, and performs reliably in all temperatures – especially in winter conditions where diesel fuel may freeze and cause complications.

Restores Power and Reduces Fuel Consumption

Over time, injectors accumulate carbon deposits, which disrupt the spray pattern and may even cause injector leaks. This increases fuel consumption, emissions, and smoke while reducing power and driving comfort. In modern Common Rail engines, injectors operate at extremely high pressures (up to 2000 bar) and have tiny clearances (1–3 micrometers). Even a small impurity can cause injector sticking or failure. AMSOIL diesel injector cleaner uses the most advanced cleaning agents on the market, ensuring optimal injector performance, preventing potential issues at a minimal cost.

According to the manufacturer, this additive can reduce engine fuel consumption by up to 8%.

Lubricates Pump and Injectors

This diesel cleaner contains a carefully blended mix of lubricating agents designed to protect the system from wear, reduce friction, and simultaneously lower fuel consumption.

Diesel Additive that Boosts Cetane and Power

A higher cetane number ensures more complete combustion and easier engine starts. Diesel All-In-One can boost the cetane number by up to 4 points, improving startup reliability, smoothing idle, and reducing both smoke and emissions.

Enthusiasts love it -> Cetane can be considered the “octane rating” of diesel fuel, the benefits in a high-performance diesel engine are undeniable.

Prevents Fuel Gelling in Freezing Temperatures

In winter conditions, the paraffin naturally present in diesel fuel begins to crystallize, causing blockages in the fuel filter. AMSOIL Diesel All-In-One lowers the cold filter plugging point (CFPP) by up to 22°C, ensuring reliable engine starts even in extremely cold weather.

Extends Fuel Filter Life

As diesel fuel circulates through the hot engine bay, deposits can form and accumulate in the filter. Diesel All-In-One reduces deposit formation, extending the filter’s lifespan and improving the fuel system’s overall performance.

Popular for Year-Round Use – Pays for Itself

Many of our customers use this additive year-round, adding a mild dose to their fuel. Word on the street suggests that the savings in fuel consumption (and potential future repair costs) might just pay for the additive itself – and that could very well be true.

Easy-to-Use and Effective Diesel Additive

• Dosage: A normal 473 ml bottle treats up to 160 liters of diesel fuel. It can also be used in smaller doses for continuous use. This 1.9L will take you far!
• Usage: Pour the additive into the tank before refueling to ensure proper mixing with the fuel.
• Suitable for: Passenger vehicles, heavy equipment, machinery, and marine engines.
