Trucks, buses, generators and boats: in through the filler. On most cars the filler has an anti-siphon valve, so please don't push it down the filler: a workshop can fit it through the fuel-pump opening.

Fitted at the next refuel
Trucks and machines take it at refuelling; most cars are fitted at a workshop. About ten years without maintenance
Gas modules are fitted on the gas line by trained installers; ships start with a pre-installation survey. Fuel is hazardous and flammable: do not smoke near the fuel tank.

Questions
Which model do I need?
Pick by fuel and tank size, one unit per tank: G-Ball or D-Ball up to 20 L, G10A up to 60 L, G10 / G11 or D10 / D11 up to 100 L, D20 / D21 up to 200 L, D50 / D51 up to 500 L. Ships take one MFS-T10000 per 10,000 L of tank; gas burners take the Industrial Gas Saving Module. Product Selector →
Does it work on gasoline, diesel and gas?
Yes. The Gasoline and Diesel Fuel Enhancers go into the fuel tank; the Industrial Gas Saving Module goes on the gas line to burners running on LPG, PNG or CNG; ships use the Greentech Marine Fuel Saver.
How much will we save?
Published results mostly fall between 5% and 25% less fuel. The figure depends on the engine and its duty: an engine that is already efficient starts from a bigger base, so the same gain shows up as a smaller percentage. Results vary with engine, load and duty. How the saving is calculated →
Is there any maintenance?
None. There are no consumables, nothing is wired or changed on the engine, and the unit stays in the tank for about ten years.
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 also be ordered online. Find a distributor →
