From the first laboratory reports in 2006 to a Vietnamese government inspection centre in 2025; from ready-mix fleets in Dubai and LPG plants in India to public buses in Addis Ababa — every figure on this page comes with its original document. Open it and you will see the letterhead, the signature and the stamp.
Why a range? Each vehicle is compared with its own original fuel use — the same vehicle, in the same test, before and after fitting. That original figure is the denominator: a vehicle that already runs efficiently shows a smaller percentage for the same fuel saved. Vehicle type, age, engine condition, load and route all differ too, so every vehicle’s saving is different. That is why we show the measured range, with every original document attached — find the result closest to your own vehicles.

Foundries, heat-treatment shops, ceramics, glass, pipe and auto-parts plants fit Greentech modules on the gas lines of their LPG and natural-gas (PNG) burners. The figures come from each plant’s own gas meters and production records — and the purchase orders they paid are below.

From letters signed by fleet managers and general managers.
“The product has met our expectations and we are satisfied with the results. The devices after installation have resulted in a saving of 10% fuel usage and we plan to install this device in total fleet phase-wise.”
Arshad HussainProcurement Manager · Unimix, Dubai“The drivers noticed that the trucks which installed Greentech devices performed better in overall engine performance, with less exhaust emissions. We are looking forward to install Greentech to our entire fleet.”
Engr. Hesham ShalabyFleet Maintenance Manager · Steady Routes Logistics, Riyadh“We have tested your products for 15 vehicles (light and heavy vehicles) for more than 3 months, where we found the performance of all the devices is up to our expectation. As an average, the fuel saving was between 15% to 25%.”
Althaf KhaziGeneral Manager · Belhasa Engineering & Contracting, Dubai“We found a real difference by installing Greentech units … saving of 10% of fuel consumption for the vehicle without any problems or obstacles.”
Ahmed H. YounisGeneral Manager · White Crown Transport Trading & Services, DohaQuoted from the original letters.
Greentech grew out of the Mtech fuel saver developed by Moletech in Taiwan. From 2006 it was sent to laboratories and universities in the United States, Australia, Hong Kong and Taiwan. These reports mark where the technology started; for today’s products, see the official tests and fleet results above.
An independent test house in Wisconsin ran the SAE J1321 fuel-consumption procedure on a 2005 Toyota Corolla 1.8L: 40.15 → 42.53 mpg (+5.93%). MGA Research does not certify or endorse products; results relate to the tested vehicle.
A California laboratory ran FTP-75 emission tests on a Chevrolet Tahoe, a Dodge RAM, a Toyota Camry and Kenworth Class 8 and Class 9 trucks; the reports record lower THC, CO and NOx. FTP-75 measures emissions, so we quote no fuel figures from it.

Air Automotive Australia — DOTARS test facility T2335, an ISO 9001 laboratory — tested a 2006 Holden Commodore 3.6L to Australian Design Rules 79/01 (emissions) and 81/01 (fuel consumption); the executive summary of report MTC001b (October 2007) records a 28% cut in greenhouse gases.
Chassis-dynamometer test on a 2003 Lexus/Toyota 3.0L at the university: 10.9% fuel saving.
The Graduate Institute of Biomedical Materials analysed 95 and 98 octane petrol by FTIR spectroscopy and viscometry; the results are consistent with smaller fuel-molecule clusters and lower viscosity.
Taipei City EPB inspection station: 1996 Toyota, idle CO −90% and HC −90%; 2004 Honda CR-V, idle HC −86%. Chun Yuan Vehicle Technology: 2003 Toyota, idle HC 127 → 4 ppm (−96.85%).
