Virdine Biodiesel Usage Guidelines
Biodiesel should not impact or void the manufacturer's warranty of any compression-ignition
motor (diesel), however, it's always safest to check your warranty first. We suggest that you contact
the manufacturer if unsure.
At a 5 - 20% blend with ULSD (Ultra Low Sulphur Diesel) the fuel will operate, as would any normal
diesel. At higher blends and at 100% biodiesel the following information should be noted:
Fuel Filters
Conventional fossil fuel leaves a dirty deposit within the fuel tank. When Biodiesel is used it
breaks down the deposits and effectively ‘cleans’ the tank and fuel pipes. So when you first switch to
Biodiesel, check the fuel filters often and change them when needed. The first few weeks
are the most critical but we would recommend checking weekly for the first 2000 miles.
Rubber
Any rubber parts in the fuel system may corrode in time with Biodiesel, especially 100% Biodiesel.
Newer vehicles and boats (since the late 1980s) do not use rubber parts. Biodiesel has been used in many older
engines without any problems. If necessary, check with your vehicle’s or boats manufacturer - its normally
a simple and low cost task to replace your fuel lines with Biodiesel friendly material.
Cold Weather Blending and Storage
Like any diesel fuel, Biodiesel can wax at low temperatures. Some types of Biodiesel wax at
higher temperatures than others, depending on the level of saturated components in the fuel - Virdine
VBio does not suffer from higher temperature waxing. Pure Biodiesel should be stored at temperatures above 0°C.
You can add anti waxing additives to the fuel, which allow its smooth operation even in very cold
weather conditions or blend with mineral diesel.
