At Darwen Diesels we make a point of stocking those hard to find specialised tools and high quality workshop consumables that we know you need including calibration fluid.

Calibration fluids are simulated fuels that have the physical properties designed specifically to replicate diesel fuel. Calibration fluids are specially designed and formulated to meet the tight specifications demanded when calibrating, flowing and flushing fuel pumps and injectors.

Smooth in texture, with high anti corrosion properties, our calibration fluid is ideally suited for use in nozzle testing systems and all types of hand operated and powered pump test stands.

This is an essential component in order to render accurate and consistent results in diesel injection test equipment. It is also extremely useful as a corrosion prevention oil for the internal preservation of fuel systems.

The Calibration Fluid we stock comes in a 20 litre container and is fully ISO4113 compliant. We have this product in stock and available for next day dispatch.
