Diesel Fuel Specification
Quality
Diesel engines for 2007 and later model year vehicles are designed to operate
only with Ultra Low Sulfur Diesel (ULSD) fuel. Use of fuel other than ULSD
will reduce the efficiency and durability of the engine, permanently damage
the advanced emission control systems, reduce fuel economy and possibly
prevent the engine from running at all. Manufacturer's warranties are likely to
be rendered void by usage of improper or incorrect fuel, and usage of fuels
other than ULSD fuel in diesel-powered vehicles is illegal and punishable
with civil penalties. Use of fuel additives to compensate for the lower sulfur
content is NOT recommended by Volvo Trucks North America.
The proper selection of fuel is essential for good economy, performance and
engine life. No. 2D ULSD should be used when climatic conditions permit.
No. 1D ULSD can be used during cold weather conditions. Blends of No. 1D
and No. 2D ULSD fuels can be used to suit various climatic conditions.
The use of lighter fuels (grade No. 1-D) can reduce fuel economy.
Euro 4 Engines
Ultra Low Sulfur Diesel (ULSD) fuel with a maximum sulfur content of
15 ppm is required to meet emission certification for Euro 4 emission engines.
Using approved diesel fuel with a maximum sulfur content of 500 ppm in
Euro 4 emission engines will meet all reliability standards.
The fuels used must be clean, completely distilled, stable and non-corrosive.
Always try to keep the fuel tank full. DO NOT put alcohol into the fuel tank.
Fill the tank after completing driving for the day.
