Compatible with all types of engines!

“The engine and injector cleaner recognized by all main engine builders!”

The ashless natural composition of the Xbee fuel additive is harmless to all engines. Xbee additive is “substantially similar to fuels”, hence compatible with all types of engines.


For light and heavy vehicles (cars, lorries, buses, construction vehicles, farming vehicles, etc.), Xbee Enzyme Fuel Treatment complies with standards established by the CEC.
The Co-ordinating European Council‘s goal is to develop performance tests for fuels, lubricants and other fluids. This European benchmark organization is approved by more than fifty automobile manufacturers, oil companies and oil manufacturers. Prodrive, a laboratory based in England, ran two of its tests on the Xbee Fuel Cleaner. CEC F-23-A-01 for diesel engines and CEC F-05-A-93 for petrol engines.

The approach in the maritime industry is different in so far as marine engine builders are very strict regarding the use of additives in their engines. The Xbee fuel additive was first subject to a composition analysis by the DNV. Det Norske Veritas is an international risk management service provider, whose in-depth analysis of the Xbee biotechnology’s chemical composition demonstrated that this enzyme-based product presents no danger to engines or their components.

On the strength of this assurance, some engine builders such as Wärtsilä Finland Oy and its Swiss subsidiary responsible for 2-stroke engines, as well as Caterpillar Motoren GmbH for its Cat and MaK engines, have drafted letters of either non-objection or recommendation based on their observations.
