Klarius Engine Fluids

The professional-grade engine fluids range from Klarius Products has been extended to include Engine Flush, Diesel System Cleaner, Petrol System Cleaner and a DPF (diesel particulate filter) Regeneration Aid. Designed for everyday use, they are all formulated and manufactured in the UK, ensuring excellent cleaning and protection for engines, fuel and emission control systems. All four fluids in the range are compliant with the latest safety and environmental standards. Each has been designed to improve system performance and help to safeguard long-term vehicle reliability.

Klarius Engine Flush is designed to purge harmful sludge and carbon from the engine prior to an oil change. Suitable for either petrol or diesel cars, the flush helps to stabilise cylinder compression, extends the service life of exhaust devices and reduces emissions while lowering fuel and oil use.

Petrol System Cleaner removes varnish and gum from the fuel system. When added to a half-full tank, it clears EGR valves and tackles carbon deposits, which helps to improve cold engine starting.

Diesel System Cleaner is used in the same manner, helping to clean injectors, compression rings and valve seats, with benefits including improved fuel economy and reduced emissions.

DPF Regeneration Aid is formulated to allow soot burn-off inside the device at lower temperatures. This is useful for diesel vehicles that only conduct short journeys where high regeneration temperatures aren’t typically reached, preventing clogging and power loss.
