Certification milestone · CNAS L23122
The CNAS-accredited testing laboratory under registration L23122 issued the formal independent report covering the Shandong heavy-duty road campaign and the Bali marine field evidence. International recognition is supported through ILAC-MRA mutual recognition and CMA metrology mark 202419120184.
Field test · Road freight
Long-distance reference run on a commercial heavy-duty truck under controlled-fuel documentation. Operational data logged continuously and submitted for independent verification.
No filler, no generic blog posts. Each entry exists because it supports credibility, proof or market communication.
Event · Market presence
Valais motor show. On the stand of our partner ATVE (stand 2304): the 1 L road bottle, dosed at 1:10,000, and the 1 L marine glass bottle, which treats 500,000 L of fuel. Developed, produced and sold by Virgo Global Energy SA in Switzerland.
Field test · Marine
Marine operational evidence documented aboard M/V KAYRA under marine fuel oil conditions, with continuous fuel-consumption logging and formal laboratory submission.
Certification
The accreditation marks identify the issuing test laboratory. They support the evidence chain and must never be confused with accreditations held by Virgo or NTROPYX.
Bench measurement
Less fuel per kilowatt-hour, more power at every load point. Fuel weighed, not metered: two runs of at least 2 h on the road engine, of at least 48 h on the marine engine, for each condition. Expanded uncertainty ± 2.0% per reading. Power +17.5% and +18.0% on average, as the laboratory prints it, ± 1.5%.
−15.2% · −15.0%
The fuel's standard parameters do not measurably change. Its ignition quality does. Eleven comparative analyses before and after treatment (appendix C.3). The reports give the laboratory's conclusion, not the individual values: no measurable change in standard physicochemical parameters, within the detection limits of the methods. Cetane number 52 → 56 on the road diesel, ISO 5165.Source Test reports GBT104002131 (Scania) and GBT104002132 (Caterpillar), March 2026.
