Proprietary Greentech
Fuel Enhancing Technology

A patented, passive fuel enhancer that sits in the fuel tank. It helps the fuel atomize finer and burn more completely — no additives, no electronics, no engine modification.

01 · How it works

It works on the fuel — before the engine ever sees it

One fuel, three places. Nothing is added to the fuel, and nothing on the engine is changed.

1

In the tank

The enhancer lies fully immersed in the fuel. No wiring, no power, nothing to adjust.

2

At the injector

The fuel atomizes finer, so more of it meets oxygen.

3

In the cylinder

More of every drop burns: more work from each litre, less CO and HC at the tailpipe.

02 · What changes

Coarse drops leave fuel unburned. A finer spray burns more completely.

Untreated fuel
COHCsmoke
  1. Fuel molecules cling together in clusters
  2. Coarser droplets leave the nozzle
  3. Part of each drop leaves unburned — as CO, HC, smoke and carbon deposits
With Greentech
CO ↓HC ↓
  1. The fuel reaches the injector more dispersed
  2. A finer spray mixes with more air
  3. A more complete burn: more energy per litre, lower CO and HC

Why finer matters

Split one drop into eight drops of half the diameter: the same fuel now has twice the surface in contact with oxygen — and fuel evaporates and burns from the surface of each drop.

    Ethiopian government test (ECAE, 2022): same distance, 17.95% less petrol and 33.6% less diesel — report ↗. In daily fleet use: typically 5–25% — e.g. IFFCO (UAE), six heavy trucks, 7.4% less diesel on average, Savex-measured — fleet report ↗. Each % is worked out against that vehicle’s own original fuel use, so the same fuel saved can show as a different percentage on different vehicles.

Each result compares the same vehicle before and after fitting, in the same test — results are not averaged or compared across tests. Tests from 2006–2009 used the first-generation product (Moletech); today's Greentech is the improved second generation. Results vary by engine condition and operating environment.

05 · What it is — and isn't

Passive, physical, nothing to maintain

Greentech D10 — the enhancer and its box
  • Not an additive

    Nothing dissolves into the fuel; its specification stays the same.

  • Not electronic

    No battery, no wiring, no power supply.

  • No engine changes

    No ECU tuning, no parts replaced; the engine stays as built.

  • Nothing used up

    Passive and not consumed. Designed for 10+ years of service.

  • Any climate

    Measured in the lab at 0 °C; in daily use from the Gulf to Southeast Asia.

  • Common fuels

    Petrol, diesel, LPG and CNG — vehicles, generators, machinery, vessels.

Questions

What buyers ask us most

Does Greentech change my fuel?

No additive goes into the fuel. Vietnam Energy Inspection (EIC) tested RON 95 petrol before and after: 25 fuel-quality tests showed no significant change (RON 95.1 → 95.1). What changes is how the fuel behaves at the injector — it atomizes finer and burns more completely.

Where does it go, and how is it installed?

Inside the fuel tank, fully immersed in fuel. Motorcycles, buses, trucks, boats and generators: drop it in through the filler. Passenger cars: fitted at a workshop, because on an ordinary car it does not go in through the filler. The tank is drained, then the enhancer goes in through the fuel-pump opening or where the filler pipe joins the tank, underneath. Labour costs vary, so ask the workshop first. LPG/CNG: a module in the gas line. Vessels: one per 10,000 L of tank capacity.

How soon does it work?

In the laboratory the viscosity change was measured 30 minutes after contact. On the road, compare a few full tanks before and after on the same route and load — kilometres per litre, or litres per hour for machines.

Is it safe for my engine?

It does not modify the engine or its electronics, and the fuel stays within its specification. Because combustion becomes more complete, engine output can rise: for marine engines, and engines already run close to their rated limit, confirm with the engine manufacturer before installing.

Why do savings differ from vehicle to vehicle?

The saving comes from fuel that was not burning completely. Older engines, carbon build-up and heavy loads leave more room; a new, well-tuned engine leaves less. How the percentage is calculated matters too — see how savings are calculated.

How long does it last?

It is passive and nothing is consumed; one unit is designed for 10+ years of service.
