Gasoline Fuel Savers
Motorcycles, cars, taxis and small gasoline engines
Under 10,000 L per tank: one D50 per 500 L (2,000 L = four). Before fitting an MFS: a pre-installation survey of the vessel, and a check with the engine maker. Size a boat's tanks →
How it is fitted
Motorcycles, trucks and machines: three steps, about five minutes
Open the fuel cap
Drop the enhancer in through the filler neck
Close the cap, refuel and drive as usual
Twin-tank trucks: one unit per tank (the D20 and D21 come with two).
D50 / D51 in large tanks and boat tanks: drop in at refuelling or through the inspection hatch; tanks with baffles are positioned by an installer.

Gas saving module
Fitted on the gas line by trained installers; the burner and its controls stay as they are. The gas meter shows the before-and-after most directly.
Marine Fuel Saver
Placed in the tank, above the sludge layer: one per 10,000 L of capacity, one in each separate tank, for tanks of 10,000 L and more. It goes in during a normal port call, after a pre-installation survey and a check with the engine maker. Boats with smaller tanks take D50s instead, one per 500 L, dropped into each tank.

What is the difference between a single unit and a complete set?
Complete sets, the models ending in 1 (G11, D11, D21, D51), add an Air Refiner to the fuel enhancer. It sits in the air filter housing, on the intake side before the filter, so the fuel side and the air side are treated together.
Blister pack or gift box: what changes?
Only the packaging. The enhancer inside is the same. Single units come in a blister pack, the G10 and D10 also in a gift box, and complete sets in a gift box only.
Will it work in my car? How is it fitted?
Yes. Passenger cars, gasoline or diesel, are fitted at a workshop: 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 by area, so ask your workshop for a price first.
Is there any maintenance? How long does it last?
No maintenance. There are no consumables, nothing is wired or changed on the engine, and the enhancer stays in the tank for about ten years.
Is there a warranty?
Yes. Register the serial number for the 12-month product warranty. It covers the unit itself: if something goes wrong with it after installation, we replace it with a new one. Verify & register →
Where do we buy?
From the authorised Greentech distributor in your country, or directly from Greentech in Taiwan where there is none. Single vehicles can be ordered online; fleets and plants, please ask for a quote. Find a distributor →
