A UK Distributor for a Proven Japanese Technology
FuelMarble is the trading name of MICCHO LTD, incorporated in England & Wales (Company No. 17197924) with a registered office at 124 City Road, London EC1V 2NX. We bring an established Japanese fuel-efficiency technology to drivers, fleets, and businesses across the UK, United States, Canada, and Mexico.
The technology is not new or experimental. It was developed over more than a decade in Japan and deployed at scale internationally before reaching our markets. Our role is distribution, support, and honest measurement, helping every customer see their own before-and-after numbers rather than take a claim on faith.
That is the line we hold: we do not ask you to believe a marketing figure. We point you to the independent record, the lab data and verified vehicle results on our technology page, and let it speak for itself.

Backed, Cleared, and Patented
Plenty of products claim to save fuel. What separates a serious company from a garage-shelf gadget is whether independent bodies have examined the technology and put their name to it. FuelMarble's has been, by a national competition regulator, by the patent system, and by a university research programme.
We treat those as credentials, not as a promise of your specific saving. The evidence for how the device actually works, the measurements, the mechanism, and the verified vehicle results. Is set out in full on our technology page.
