🌿 Beyond fuel: for many fleets the main reason to buy is emissions — government bus tests measured smoke down by up to 85%, idle CO cut to zero, 9 of 10 buses passing. Inspections, carbon targets and ESG are where this device fights.

Official rating: diesel up to 10%, gasoline 15–20% — measured higher in heavy-duty markets: Ethiopia official tests +33.6% diesel / +18% gasoline; Qatar heavy truck +34.6%. The more efficient the vehicle, the smaller the % looks — the litres still add up.

🌿 Fuel is only half the story — the emissions gains (smoke down up to 85%, idle CO to zero) carry inspection and ESG value on top.

Questions

Before you order

Will it void my vehicle warranty?

No. The device is passive — no chemicals, no electronics and no engine modification — so the vehicle warranty is unaffected.

How soon will I see results?

The device activates within about 30 minutes. For a reliable before-and-after comparison, record fuel consumption over two to four weeks of normal use.

My tank is larger than 100 litres — which model do I need?

Choose D20/D21 for tanks up to 200 litres or D50/D51 for tanks up to 500 litres.

How do I register the warranty?

Enter the serial number from the packaging at our product registration page. Warranty runs 12 months from registration.

Does it need maintenance or replacement?

No maintenance, no refills. The service life is 10 years; after that, simply replace the unit.

How do I know my unit is genuine?

Every genuine unit has a serial number you can verify on the registration page. Units bought outside authorized channels cannot be registered.
