How It Works
Simple install. Immediate impact.
Install in Fuel Line
FET is fitted directly into the vehicle's fuel supply line — no engine modifications, no downtime. Compatible with all diesel and petrol engines.
Activates with Engine Heat
As the engine reaches operating temperature, FET's catalytic process begins treating the fuel passing through it, restructuring fuel molecules.
Improves Combustion Efficiency
Better-structured fuel burns more completely, extracting more energy per litre — translating directly into fuel savings and lower emissions.
Proven Results
Documented in real-world conditions.
~10.9%
Fuel Savings
Field test — Unimog winter operation
Measured over an extended field test in cold-weather conditions with a Mercedes-Benz Unimog. Consistent savings across the test period.
Up to 15%
Fuel Savings
Lab test — constant-speed runs
Controlled laboratory testing at constant speed showed up to 15% improvement in fuel consumption versus an untreated baseline vehicle.
Key Benefits
Built for operational realities.
Easy to Retrofit
Fits any diesel or petrol engine without mechanical modification. Installation takes under an hour.
Measurable Impact
Savings are documentable. Before/after fuel logs give you clear evidence for fleet reporting.
Reduce Emissions
More complete combustion means fewer particulates and lower CO₂ per kilometre driven.
Fleet Logic
The more vehicles in your fleet, the stronger the ROI. Savings compound across every unit.
Documented & Verifiable
Results backed by independent field and lab tests. Not marketing claims — measured data.
Ready for Real-World Operation
Proven across passenger cars, trucks, agricultural machinery, marine, and construction equipment.
