The fuel analyses prescribed in the fuel standards DIN EN 590 and DIN 51603 are suitable for ensuring quality when selling to customers. However, the fuel analyses prescribed in the standards do not allow reliable statements to be made about the long-term shelf life of a fuel.

Tec4Fuels has therefore selected a number of additional fuel parameters that are relevant for long-term storage and has them analyzed for fuel quality testing by accredited analytical laboratories using standardized procedures. Based on these parameters, such as oxidation stability, valid statements can be made about the quality and usability of a fuel.
