TBK Trading PLC is the authorised Greentech Fuel Saver distributor for Ethiopia, based in Addis Ababa. We supply the device, fit it, and support it afterwards — on cars and taxis, minibuses, city buses, trucks and generator sets.
Ethiopia runs more than 1.5 million vehicles on imported fuel, and Directive No. 1051/2017 sets limits on the pollutant gases they are allowed to emit. For an operator here the two problems are the same problem: what leaves the exhaust is what did not burn in the cylinder. Greentech was launched to the Ethiopian market at a press conference in Addis Ababa in April 2026.
Three independent parties have measured this device in Ethiopia, and every number they produced is published below — the favourable ones and the unfavourable ones.
The Ethiopian Conformity Assessment Enterprise (ECAE) tested it in May 2022 under the national standard CES 6655:2021. Petrol economy rose 17.95%; diesel economy rose 33.6%, on named vehicles with their plates recorded.
Bureau Veritas — a world name in testing and inspection — ran the programme again in May 2023 on the Addis Ababa–Adama Express Road, over 148 km per vehicle, to the same standard. Petrol rose 17.00%, diesel rose 36.22%. Two laboratories, a year apart, on different cars, landing within a point of each other on petrol and within three on diesel.
The same 2023 report answers the question every fleet manager actually asks: does it still work later? Bureau Veritas re-tested a Toyota Hilux that had been running with the device fitted since May 2022. Twelve months on it was still 13.39% better than its original baseline. That is not the same number as the 23.5% recorded on the day of fitting, and it should not be read as one: these are road runs on public highway in live Addis Ababa traffic, not bench tests, and the conditions of the day move the absolute figures. What the re-test settles is the question that was asked — a year later, same vehicle, same laboratory, same national standard, still clearly ahead of where it started.
Then there is the evidence we would actually put in front of a fleet manager. Two separate Addis Ababa public bus operators fitted the device and kept their own fuel logs. The Anbessa City Bus Service Enterprise recorded bus 8407 — 300-litre tank, four fills before and twelve after — dropping from 0.45 to 0.41 litres per kilometre, 8.89%. The Sheger Mass Transport Service Enterprise recorded bus 3A-70831 AA over 2,129 km before and 2,333 km after, dropping from 0.432 to 0.400 litres per kilometre, 7.42%.
Neither operator was measuring for the other. Two public transport authorities in the same city, on their own buses and their own routes, landed within one and a half points of each other. Both letters are on enterprise letterhead, signed, stamped and downloadable below.
The device is fitted once, inside the fuel tank. It needs no power, no additive and no maintenance, it does not modify the engine, and it carries a ten-year service life.
We would rather you measured it than believed us. Record fuel and odometer for a month, fit the device, record another month, compare. That is exactly what every test above did.
Which of these is your fleet? Most of what we fit in Ethiopia falls into five groups. City buses on 300-litre tanks — the class Anbessa and Sheger measured — take the D50. Mid-size trucks and minibuses take the D20. Pickups, light commercials, generator sets and water pumps take the D10, the class of the Toyota Hilux in both laboratory tests. Petrol saloons and taxis take the G10A, the class of the Mitsubishi Attrage and Suzuki Swift. Motorcycles and three-wheelers take the G-Ball. Hotel, bakery and factory gas burners take the LPG module. If your fleet is a mix of these, say so — most are.
What happens after you order. TBK fits it, or trains your own workshop to. How it goes into the tank depends on the vehicle: trucks, buses, generator sets and motorcycles take it through the filler at refuelling. On most cars the filler has an anti-siphon valve: please don't push it down the filler, because it can get stuck and the pump will keep cutting off when you refuel. A workshop can fit it through the fuel-pump opening. The device sits in the fuel tank, needs no power and no additive, and is not serviced afterwards. Every unit carries a serial number printed on the packaging, and you can check any serial yourself at greentech.tw/products/product-register/ — before or after purchase, no account needed. If a unit does not verify, it did not come from us. Ask TBK for the warranty terms in writing together with your quotation.

Bureau Veritas measured a Suzuki Swift at 21.29 km/L before fitting and 24.92 km/L after. A year earlier ECAE had measured a Suzuki DZIRE at 20.74 and 25.28 km/L. Two laboratories, two vehicles, two years apart: the baselines sit within 0.6 km/L of each other and the after-figures within 0.4. Every percentage in the table answers one question — how much less fuel the vehicle burned to cover the same distance — so the rows can be read against each other directly. Where a report published the same measurement the other way round, as a gain in kilometres per litre, it is converted here; where an operator worked in litres per kilometre, the same figures are shown in kilometres per litre.
Diesel gained more: Bureau Veritas took a Toyota Hilux 4x4 from 15.43 to 21.02 km/L over a supervised road test. The result we find more useful came a year later. A Hilux fitted in May 2022 was re-tested by the same laboratory in May 2023 and was still 13.39% above its original baseline. Public-road testing cannot reproduce traffic, load and driving conditions from one year to the next, so the two runs are not the same test — but a year after fitting, the vehicle was still measurably ahead of where it started, measured by the same laboratory to the same national standard.
The evidence we put the most weight on did not come from a laboratory. Anbessa City Bus Service Enterprise recorded 8.89% less fuel on bus 8407, from its own fill log and its own calculation. Sheger Mass Transport Enterprise, working entirely separately, recorded 7.42% less fuel per kilometre on bus 3A-70831 AA. Two public operators in one city, their own buses, their own routes, no shared method — and they landed a point and a half apart. The Sheger letter is addressed to the distributor who held the territory at that time.
Two vehicles in the 2023 report returned figures above 60%. We do not quote them and we build nothing on them. Across every published Greentech test worldwide, documented savings run from roughly 5% to 25%, depending on engine condition, duty cycle, load, fuel quality and route. That is the range we stand behind, and the reason we publish the reports in full rather than a single headline number.
Oxides of nitrogen fell on both diesel vehicles tested. The other measured gases moved in different directions on different vehicles, and hydrocarbons on the petrol vehicles read above the analyser's range, so nothing can be concluded there. The full measurements are in the report. We present these as test reports, not as certifications.
In 2025 the Ministry of Transport and Logistics issued Directive No. 1051/2025 on emission control of pollutants from vehicles, under Road Transport Proclamation 1274/2022. It requires fuel-powered vehicles to meet the emission standard approved by the Ethiopian Standards Institute, and sets a measurement and certification timetable for registered vehicles. The Oromia Transport Agency issued its own implementing directive in January 2026. Operators should confirm their own position with the Ministry or their inspection centre; we are not in a position to advise on it.
Each model is sized to a tank. Tell us the vehicle or the equipment and we will confirm the right one before you order.
D10 Pickups, light commercials, generator sets and water pumps. This is the size class of the Toyota Hilux that Bureau Veritas and ECAE both road-tested on the Addis Ababa–Adama route.
D20 Mid-size trucks, minibuses and mid-range commercial vehicles. Supplied into Ethiopia alongside the D10 as the working pair for mixed fleets.
D50 Long-haul trucks, cranes and city buses. This is the size class of the 300-litre city buses that Anbessa and Sheger recorded in their own fill logs.
D-Ball Small diesel engines: portable generators, pumps, single-cylinder machinery and light agricultural equipment.
G10 Saloons, SUVs and petrol taxis, and small boats. The larger of the two petrol sizes.
G10A Cars, taxis, motorcycles and small petrol generators. This is the size class of the Mitsubishi Attrage and Suzuki Swift used in the ECAE and Bureau Veritas tests.
G-Ball Motorcycles, three-wheelers and small petrol engines — the highest-volume vehicle class on Ethiopian roads.
LPG LPG and CNG engines, and industrial gas burners in hotels, bakeries and factories. Sized to the gas line rather than to a fuel tank.
Dealer networks, service workshops and trade shows across Ethiopia — the people who already sell and fit this product every day.
Some people come here because they burn the fuel. Others come because they want to supply or fit the device in their own area. Tell us which you are and the form will ask the right questions.
