We often get questions about which diesel should be used in Vetus Diesel engines and whether biodiesel or diesel with added biodiesel can be used.
This is described in your engine manual, but here are the recommendations that apply 01.11.2022

Fuel Quality Grade
Use only diesel fuel or diesel blends with up to 7% FAME (B7), with less
than 0.5% sulphur content of which the quality is fully controlled and
conform the standards below.

The following fuel specifications / standards are approved:

• CEN EN 590:2009
• ASTM D975-09

Don’t use fuel with more than 1% sulfur!
The cetane number must be at least 49.

The exhaust emission levels determined during certification by the supervising authority are always based on the reference fuel described by law. These fuels match the diesel fuels which are in accordance with CEN EN 590 andASTM D 975. Emission levels cannot be guaranteed with other fuels.

Biodiesel:

Use only the prescribed diesel fuel or diesel blends. Do not use 100% biodiesel (B100)!
Although the use of biodiesel is allowed in diesel blends with up to 7% FAME (Fatty Acid Methyl Esters) (B7) fast degradation of the biodiesel should be taken in account.

Problems caused by using FAME of poor quality or degraded fuel are not covered by warranty.
