The car you drive every day is where fuel money hurts most
Commuting, school runs, weekend trips — sedans and SUVs with tanks up to 100 litres are its home ground.
Fuel spend only ever goes one direction: up.
Grab Vietnam measured 9.5% average across 20 vehicles — real money back every year, before counting a smoother engine.

How to check: open the fuel cap and shine a light into the filler neck. A single spring flap the nozzle pushes open means you are fine to use it. A metal screen or ball deeper in the pipe, or a capless filler, means an anti-siphon device — do not order a drop-in enhancer for this vehicle.
🌿 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.

Grab Vietnam, 20 vehicles (2025)
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.

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?
Gasoline models top out at 100 litres; for diesel tanks up to 200 or 500 litres see D20/D21 and D50/D51. Contact us for special gasoline applications.
