SGS fuel analysis – Australian Diesel Oil

In May and June 2023, the independent and accredited laboratory SGS received a sample of diesel oil supplied by the engine workshop Australian Marine Services, established in the province of Victoria, Australia.


The laboratory analyzed the regular fuel, then treated a sample with XBEE Enzyme Fuel Technology at the advised ratio of 4,000:1. This additized sample was stored for a few weeks in order to simulate storage, and was finally analyzed according to the Australian standard CAN/ CGSB-3.51-2020.

Among the most notable elements, we can notice that the lubricity is improved, going from 440 to 410 µm of wear, i.e. a 6.8% improvement.
