7. FUEL SPECIFICATIONS

The quality of fuel used for high-speed diesel
engine operation is a very important factor in
obtaining satisfactory engine performance, long
engine life and acceptable exhaust emission
levels.
The U.S. Environmental Protection Agency
(EPA) has issued new standards to improve air
quality by significantly reducing emissions
through a combination of cleaner-burning diesel
engines and vehicles.
To meet EPA standards, the petroleum industry
produces Ultra Low Sulfur Diesel (ULSD) fuel,
also referred to as S15, containing a maximum
15ppm (parts-per-million) sulfur.
On-highway diesel engines
emission regulations are designed to operate
ONLY with ULSD fuel. ULSD fuel will enable the
use of cleaner technology diesel engines and
vehicles with advanced
devices, resulting in significantly improved air
quality.

7.1 FUEL TYPE

EPA-10 engines like the Volvo D13 are
designed to run on Ultra Low Sulfur Diesel
(ULSD) fuel, which can contain no more than 15
ppm sulfur.
Fuel used must meet engine manufacturer's
specification. Refer
specifications.
CAUTION
ULSD fuel is necessary to avoid fouling the
engine's Exhaust Aftertreatment
Improper fuel use will reduce the efficiency of
the engine's Aftertreatment System and may
permanently damage the system.

Section 03 revised September 2016
CAUTION
Owners of 2010 and later model year on-
highway diesel engine must refuel only with
ULSD fuel.
NOTE
Burning Low Sulfur Diesel fuel (instead of
ULSD fuel) in 2010 and later model year
diesel engines is illegal and punishable with
civil penalties.
NOTE
Engine and vehicle manufacturers expect
ULSD fuel to be fully compatible with the
existing fleet, including 2006 and earlier model
year vehicles. In
introduction of ULSD fuel to older vehicles
may affect fuel system components or loosen
deposits in fuel tanks. As part of a good
maintenance program, owners and operators
of existing cars, trucks and buses are
encouraged to monitor their diesel-powered
vehicles closely for potential fuel system leaks
or premature fuel filter plugging during the
change-over to ULSD fuel.
NOTE
Like Low Sulfur Diesel fuel, ULSD fuel
requires good lubricity and corrosion inhibitors
to prevent unacceptable engine wear. As
necessary, additives to increase lubricity and
to inhibit corrosion will be added to ULSD fuel
prior to its retail sale.

7.2 BLENDING

Only ultra low sulfur kerosene – No.1 diesel with
no more than 15ppm sulfur may be blended with
ULSD fuel to improve
performance. With
formulations on the market, care must be taken
to select kerosene with a maximum of 15ppm
sulfur.
Blend rates remain the same as with Low Sulfur
Diesel fuel.

7.3 BIODIESEL FUELS

Biodiesel up to a maximum of 20% blend (B20)
may be used and
