01Fuel Eco Tech
Lower fuel bills, measured on your own vehicles.
A device fitted to the fuel line, between the pump and the filter, that improves how fuel and air mix before combustion. We measure your fuel use before and after fitting, so the saving is a number from your fleet, not a promise.

Field report by CTI GmbH, Lippstadt, signed by Holger Walprecht on 10 November 2025.
That is one vehicle, in Germany. Your own result is measured in a trial on your vehicles, against their own fuel history. That is how we sell.
How it works
It works on the fuel, not the engine.
FET improves the turbulence and distribution of the air-fuel mixture in the combustion chamber, so oxygen is used more fully on every cycle.
- 01
Fitted to your fuel line
FET integrates between the fuel pump and fuel filter, outside the high-pressure system. No modification to your engine, injection system, or electronics. Fitted in under an hour.
- 02
Patented swirl chamber activates
The proprietary swirl chamber system improves the turbulence and distribution of the air-fuel mixture in the combustion chamber. Oxygen integrates more fully, so every cycle burns cleaner and more completely.
- 03
Measured results
We establish your baseline consumption, then track the difference after fitting, giving you a clear, data-backed return on investment.

What it doesn't touch
Your engine stays as the factory built it.


No engine changes
FET works exclusively on fuel preparation and swirling. It does not intervene in the combustion engine, control electronics, or exhaust aftertreatment system.
Outside the high-pressure system
Installation is carried out outside the high-pressure fuel system. No changes to your injection system or engine components are necessary.
No chemical alteration
FET does not change the chemical composition of your fuel or alter the way your engine works. It is a physical optimisation only.
Factory systems stay intact
No mechanical or electronic change to factory-set systems. If your vehicle is under a manufacturer's warranty, tell us the make and model and we'll give you written guidance for it before anything is fitted.
Which device fits
Four sizes, from a 1.0-litre car to a 40-tonne truck.
Taken from the manufacturer's application tables. Engine size is the starting point; the fuel-line diameter, injection system and how the vehicle is used decide the final fit, which we confirm at the assessment.

How this is calculated
15,000 km a year at 7.5 L/100km is about 1,125 litres; at UGX 5,000 a litre that is UGX 5,625,000 of fuel a year. UGX 5,625,000 × 10% = UGX 563,000 saved a year, per vehicle. Device UGX 1,891,000 ÷ UGX 563,000 a year = payback in about 3.4 years.
Still assumed. Replace with your own
- Fuel use is a typical figure for this vehicle class, not your vehicle. Enter your own for a real answer.
- Fuel price is an indicative Kampala pump price.
- Fuel type is the usual one for this vehicle class.
- The saving percentage is your assumption. The German field test measured 13.9% on one vehicle, in one month. Your vehicles, routes and loads may differ, which is what a measured trial is for.
An estimate, not a promise. Actual savings depend on the vehicle, its condition, routes, loads and driving. They are confirmed in a free assessment and can be measured in a trial.
How we sell it
Measure first. Then decide.
- 01
Assessment
We look at your vehicles, routes and fuel records, and tell you which device fits each one, at no cost.
- 02
A measured trial
We fit a small number of vehicles and compare their fuel use with their own history, route by route. The terms of the trial are agreed in writing before it starts.
- 03
Your decision
You see the result in a report, including if the saving is small, or none. Only then do we talk about the rest of the fleet.
What stands behind it
Each credential, and what it actually covers.
A management-system certificate is not a fuel-saving test, and an insurance policy is not a laboratory result. So we list them separately.

Questions
What fleet owners ask us.
Petrol and diesel engines right across the range, from small cars, mini-buses, and vans, through SUVs and light trucks, up to heavy long-haul trucks of 40 tonnes. Four device sizes cover every class; we confirm the exact fit for your specific vehicles during your free assessment.
No. Fuel Eco Tech works outside the high-pressure fuel system, no changes to your engine, injection system, or electronics. Your factory configuration stays completely intact.
FET does not modify the engine or any factory-set component; it works on the fuel before it reaches the high-pressure system. Warranty terms differ by manufacturer, so tell us your make and model and we'll give you written guidance for your vehicle before fitting.
We establish your current fuel consumption as a baseline, then measure consumption after fitting, so the difference is transparent and tied to real data from your fleet.
No. Fuel Eco Tech works for a single vehicle or an entire fleet. Larger fleets simply see the savings multiply across every vehicle.
