Verified Results of Fuel Savings

FuelMarble technology is backed by more than ten years of research and development in Japan.
Its performance has been validated through independent real-world driving tests conducted in Japan, China, and Indonesia.

Across all regions, users recorded an average 20.8% increase in driving distance, confirming a consistent improvement in fuel efficiency.
In China, the most recent independently certified trial demonstrated an 18% improvement in fuel efficiency following retrofitting, as documented in the Chinese vehicle test case study.

In parallel, emissions performance has also been monitored. During a congested urban test in Jakarta, FuelMarble delivered a 10.34% reduction in CO₂ emissions, indicating that improved combustion efficiency can produce measurable environmental benefits alongside fuel savings.

All findings come from independent testing, long-term monitoring, and audited verification processes.

Key Findings

FuelMarble’s technology was developed in Japan through a decade of research and engineering.

The project was a collaborative effort involving Kurume Industrial University, Kurume National College of Technology, and the Kyushu Institute of Technology.
This long-term academic partnership forms the scientific foundation behind FuelMarble’s performance.

Developed Over 10 Years by 3 Japanese Research Institutions

FuelMarble: The Only Japan-Developed Technology Proven by Scientific Data

FuelMarble is the only product in Japan whose fuel-efficiency performance is backed by university-verified scientific research.

In 2008, the Japan Fair Trade Commission (JFTC) investigated 20 companies that claimed to improve automobile fuel economy.
The investigation concluded that 19 of those companies lacked credible scientific evidence and were issued cease-and-desist orders requiring them to withdraw their advertisements.

FuelMarble was the only product not required to withdraw its claims.
Its performance data was supported by verifiable, peer-reviewed research conducted by accredited Japanese institutions.

Over 180,000 units have been deployed across vehicles and industrial applications in Asia.
This long-term adoption reflects strong consumer trust and a solid scientific foundation behind the technology.

FuelMarble technology is endorsed by Japanese regulatory bodies and developed using mineral-based thermal optimization principles that have been presented and validated in academic research settings.

Independent road tests conducted across multiple countries, verified by different organizations such as Shiao Moto Vehicle Testing Company Limited, Qinhuangdao City Ecological Environment Bureau, Automotive Engineering Society etc, confirm its effectiveness, demonstrating meaningful increases in fuel economy and a near-total reduction of harmful exhaust emissions.
