Yanmar approves use of B5 biodiesel
01 Jul 2008
In general, when compared to standard diesel fuel, B5 Biodiesel usage can reduce particulate matter and the emission of so-called greenhouse gases. A maximum 5% B5 Biodiesel is blended with standard fuel and must conform to ASTM D6751 or ISO EN14214 specifications.
However, Yanmar Marine warns boatbuilders and other customers that biodiesel blends can adversely affect certain metal, rubber and plastic components of engine fuel supply and return systems.
Biodiesel-compatible components must be used instead so deterioration and damage do not occur. Builders and/or customers must verify they are using the correct fuel supply and return system materials, otherwise they will lose their engine warranty protection.
A check with Yanmar is advised before using B5 Biodiesel in any Yanmar engine.
