Every figure on this site can be traced to the people who measured it. These are the principles we follow.
Every result names the university, institute, laboratory or operator behind it, the period and what was tested. Each source keeps its own number.
Each figure comes from a university study, a laboratory test report or a signed letter from the operator.
Independent institution, operator report or our own measurement: the same mark everywhere on the site shows where a result comes from.
Locomotives, construction and quarry machines, trucks, generators and passenger cars, measured by operators and independent institutions in everyday use.
The 7–20 % range runs from the lowest to the highest fuel result in this ledger: BPS-Prastav and Victus Networks.
Some documents are operator reports shared in confidence. We show their results here and send the full report to investors and partners on request.
The same mark and colour appear with every result across the site, so you can see at a glance where it comes from.
3entries
Measured or evaluated by a university, research institute or accredited laboratory.
6entries
Results from an operator that used BEP in its own fleet, reported or confirmed by that operator.
Raw data on request
Measured by BEP in cooperation with the operator; raw data available on request.
Filter by engine type or level of evidence. Every entry has its full card below.

Adverse effects on engines
Endoscopy showed cleaner cylinders.
Assessing nationwide adoption would call for a larger number of vehicles; NUST recommends extending the trials to fleets as the next step.
