Sulnox Eco™

The 100% Organic
Fuel Conditioner

Sulnox Eco™ improves combustion to lower fuel costs, lower emissions, and protect engines - no retrofits, no capital expenditure, just add to any liquid hydrocarbon fuel.

Seen This Before?

That Smoke is
Unburnt Fuel

When you see black smoke pouring from an exhaust, it means the fuel didn’t fully combust. This is called incomplete combustion - and it wastes energy, drives up fuel costs, increases emissions, and accelerates engine wear.

The Hidden Cause

Why Incomplete Combustion Happens

When fuel is injected, not all the droplets are small enough to fully combust. So what's left behind goes to waste: causing carbon deposits, reducing engine efficiency, and exiting the exhaust as black smoke.

How Sulnox Eco Works

The Four
Mechanisms

SulnoxEco works through four key effects - each designed to improve how fuel behaves inside your engine.

1. Emulsification

Conditions Fuel for Complete Combustion

When added to the fuel tank, the surfactants scavenge small amounts of free water already present, and disperses it into microscopic droplets within the fuel, forming a stable emulsion.

2. Secondary Atomisation

Delivers Complete Combustion

As the fuel enters the combustion chamber, the microscopic water droplets within the atomised fuel vaporise at lower temperatures. This triggers micro-explosions that fragment the fuel droplets into even smaller ones - exposing more surface area and resulting in complete combustion. That means less black smoke lower emissions, and more usable energy from every drop of fuel.

3. Improved Lubricity

Protects Engine Components from Wear

With an average c.17% added lubricity, Sulnox Eco also reduces friction across engine components - helping extend the life of key parts like piston rings and liners.

4. Detergency

Removes Deposits, Restores Efficiency.

Gently cleans away built-up carbon from engine components - and prevents future deposits - extending their lifespan.

What This Means for You

What Sulnox Eco achieves in the real world

Lower Fuel Costs

5% average saving for marine and 8% average for land applications, with >300% ROI within weeks.

Lower Emissions

c.90% particulate reduction, plus lower CO₂, NOx and SOx.

Better Engine Performance

Keeps engine components clean and lubricated - minimising internal stress and extending lifespan.

Simple Application

No equipment changes or expensive upgrades. Just a 1:2000 dose (or 1:1000 for petrol) added during bunkering or fuelling.

Adopted by Market Leaders

Expanding Sulnox Eco across our fleet was an easy decision. It's a self-funding solution that delivers tangible fuel savings, cleaner engines and supports our broader efficiency and sustainability goals
