Economy you can feel
Deposits never announce themselves. They just take a little more fuel each month for exactly the same journey. Clearing them is how you get those miles back, and you notice it at the pump rather than on the dashboard.
For cars, trucks & fleets
Cleaner engines and more miles from every tank you fill.
Every tank you burn leaves a little of itself behind. Fuelnox goes in at the pump and spends the next tankful clearing what the last few hundred litres left in your injectors.

§01 · Why it matters
Modern engines have less room for dirt.
A modern injector meters fuel through holes finer than a human hair, at pressures no engine of the 1990s ever saw. A deposit far too small to see is enough to spoil the spray pattern, and it builds a little with every tank.
Fuelnox goes in at the pump and works while you drive, then leaves with the fuel. There is nothing to fit, nothing to strip down and nothing to remember beyond the next fill.

Why Fuelnox
Five reasons to dose at every fill-up.
Clean injectors & valves
Detergents lift the sticky varnish and carbon off injectors, carburettors and intake valves, restoring the spray pattern the engine was designed for.
Smoother, stronger running
A clean, fine spray of fuel lights more evenly. That is what you feel as crisper throttle response, less hesitation from cold and fewer misfires under load.
Lower emissions & smoke
Less unburnt fuel means less soot loading the DPF and less work for the catalyst. That helps at the emissions test, and it helps the two parts you would least like to replace.
Built for fleets
One dose at fill-up needs no training, no workshop slot and no change to the routine. Across a hundred vans the numbers speak for themselves: a treated tank costs about a euro, an injector service costs far more.

Long runs
Where deposits come from
Not all miles are equal.
Two cars of the same age can have fuel systems in completely different condition. What separates them is not mileage, it is the kind of miles.
The short-trip life
School run, supermarket, ten minutes to the office. The engine barely reaches temperature, the fuel system never gets the chance to run itself clean, and deposits build faster here than anywhere else.
Hot and steady
A motorway run burns hotter and more completely, which helps. What it will not do is undo what three months of cold, short journeys already left behind on the injectors.

Low-sulphur diesel
Two changes, one answer
Modern pump fuel needs a hand.
It draws in water
Ethanol pulls moisture straight out of the air. Leave a tank part-full for a few weeks and it can drop out as a wet layer on the bottom: the classic reason a car that has stood idles rough and starts hard.
Fuelnox holds that moisture in the fuel as microscopic droplets instead of letting it separate. In the cylinder they flash to steam and burst, breaking the fuel around them into a finer spray, and the water leaves with the exhaust.
It lost its lubricity
Taking the sulphur out of diesel took its natural lubricity with it. The pump and injectors that sulphur used to cushion now run on fuel that no longer does the job.
Fuelnox puts lubricity back, easing the friction where the injection pump and injector needles meet the fuel they are supposed to be protected by.

Simple to dose.
It comes down to two doses: a stronger first treatment, then a light top-up at every fill-up. Overdosing will not harm the engine.
Shock dose
1:2000
About 20 ml per 40 litres of fuel. Add Fuelnox first, then refuel so it mixes evenly as the tank fills. Repeat where contamination is heavy.
Maintenance dose
1:4000
About 10 ml per 40 litres at each refuel or regular interval. A single 500 ml bottle conditions up to 2,000 litres of fuel.
Results vary with engine, fuel and operating conditions. For petrol, diesel and two-stroke fuel systems. Not for aviation fuels.
