SulnoxEco Fuel Conditioner | Petrol & Diesel

Get More Miles. Reduce Emissions. Protect Your Engine.

Whether you drive a classic Mini, Jaguar E-Type, Land Rover, MG or modern daily driver, SulnoxEco helps you get more from every tank of fuel.

This new dual-purpose formula is suitable for both petrol and diesel engines, making it easier than ever to improve fuel efficiency, reduce emissions and help protect your engine with one simple product.

No modifications. No complicated installation. Just add SulnoxEco when refuelling.

Why Choose SulnoxEco?

Modern fuels aren't the same as those many classic vehicles were designed to run on.

SulnoxEco is a 100% organic fuel conditioner that improves combustion, helping fuel burn more efficiently while reducing carbon deposits and improving lubricity throughout your fuel system.

Trusted in over 40 countries, SulnoxEco has been independently tested and is suitable for petrol, diesel and biofuel engines.

Key Benefits

Improve Fuel Efficiency

Independent testing has shown an average improvement in fuel economy of around 9%, helping every litre go further.

Reduce Emissions

More complete combustion helps reduce black smoke and harmful exhaust emissions while encouraging a cleaner-running engine.

Protect Your Engine

SulnoxEco gently removes carbon deposits, helps prevent further build-up and improves fuel lubricity by around 17%, reducing wear on fuel system components.

Suitable for Petrol & Diesel

One bottle treats both petrol and diesel vehicles, making it ideal for households or workshops with multiple vehicles.

How It Works

Better Combustion

SulnoxEco improves fuel atomisation, allowing fuel to burn more completely.

The result is better combustion, less wasted fuel and lower emissions.

Cleans As You Drive

The organic detergent package gradually removes carbon deposits while helping prevent new build-up from forming.

Improves Lubricity

Modern fuels often provide less lubrication than older fuels.

SulnoxEco helps restore lubricity, reducing friction and helping protect pumps, injectors, carburettors and other fuel system components.

Simple to Use

Simply add SulnoxEco directly to your fuel before refilling.
