IMPROVE FUEL ECONOMY Increase fuel economy by up to 10% due to Dipetane enabling a more efficient and complete fuel burn saving you money.

Prevents Radiator Cold Spots

Compatible with plastic and fibreglass header tanks and with all metals used in central heating systems including iron, copper, steel, brass and aluminium

CLEANS THE ENTIRE DIESEL FUEL SYSTEM Effectively removes dirt, carbon deposits, and other harmful residues that accumulate within the fuel system over time. Ensures a cleaner and more efficient combustion process by thoroughly cleaning key components such as the fuel pump, diesel injectors, and intake valves. By dissolving stubborn contaminants, it helps prevent clogging and improves the overall efficiency of the fuel delivery system. Designed to work in a single treatment, providing a powerful 'one tank' clean-up that restores optimal fuel system functionality.

Increases power and miles per gallon

Item Package Height 18.5cm

Metal de-activators which stop chemical reactions caused by dissolved metals in fuel

IMPROVES THE VISCOSITY INDEX AND STRENGTHENS OIL FILM Enhancing the viscosity index of lubricating oils is essential to ensure consistent engine performance under varying temperatures. This formulation effectively stabilises the oil s viscosity, allowing it to maintain its protective properties even under extreme heat or heavy load conditions. By strengthening the oil film, it creates a durable barrier between moving parts, reducing friction and wear. The ability to retain its viscosity under high-temperature, high-shear environments ensures optimal lubrication, prolonging the life of the engine components.

Inhibits corrosion, scale, hydrogen gassing, microbiological growth and boiler noise.

Quick and easy dosing of chemicals into central heating systems

MONEY BACK GUARANTEE We are 100% confident you will love our product but in the unlikely event you're not completely happy with your purchase we will provide you with a full refund in accordance with Amazon terms.

DOUBLE ACTION FORMULA FOR ENGINE OPTIMIZATION Formulated as a fully oil-soluble chemical treatment, this product delivers a powerful double action for engine efficiency. First, it improves engine compression, which supports consistent power delivery and enhanced performance. Second, it actively reduces wear on internal engine components, contributing to long-term reliability. By targeting two essential engine functions simultaneously, the treatment not only stabilises mechanical operation but also supports smoother running under varying driving conditions.

Powerful Additive The Diesel Fuel Additive, Hydra 2 EHN, is the best product to give a cetane boost. It is a fuel additive that acts as a performance enhancer which improves economy and performance. This diesel additive enables engines to run smoother with better pickup.

Ideal Preparation for Inhibitor Application Cleaning with X400 prepares the system for the subsequent application of inhibitors, ensuring the best possible protection against corrosion and scale in the future.

The product comes in a convenient 500ml bottle that can be added directly to your central heating system without the need for special equipment Fernox Protect F1 helps to extend the life of your central heating system, improve energy efficiency, and reduce the risk of costly breakdowns and repairs

EXCEPTIONAL HIGH-PERFORMING SUPER DIESEL FUEL. AR6900-D MAX converts low-quality supermarket diesel into high-performing Super Diesel Fuel using a carefully selected blend of pure 2-EHN cetane improver, multiple detergents, ester lubricant, stabiliser and combustion catalyst.
