9-6 Technical Information
DOB 1300-1556 PA-1639 Operator's Manual 2020 X3-45 Commuter
FUEL TYPE
Your Prevost vehicle is powered by a diesel
engine designed to operate only with Ultra Low
Sulfur Diesel (ULSD) fuel, which can contain no
more than 15 ppm sulfur.
WARNING
ULSD fuel is necessary to avoid fouling the
engine’s Exhaust Aftertreatment System. Use of
fuel other than ULSD will reduce the efficiency
and durability of the engine.
BIODIESEL FUEL
Biodiesel with up to a maximum of 5% biofuel
(B5) may be used and will not affect the
manufacturer’s mechanical warranty as to engine
and emissions system related components. The
biofuel used in the various blends must conform
to ASTM D6751; therefore B1 to B5 blends
conforming to ASTM D975. Also, any engine
performance problem related to the use of
biodiesel fuel would not be recognized nor
considered as Volvo or Prevost’s responsibility.
However, Volvo engines are certified to comply
with
U.S. EPA and California emissions
standards based upon the use of test fuels with
specifications established by these regulatory
agencies.
Alternative fuels, including biodiesel, that are not
substantially similar to the required test fuels may
adversely affect engine emissions compliance.
As a result, Volvo does not warrant the engine will
conform to applicable Federal or California
emissions limits when operated on biodiesel or
other alternative fuels that are not substantially
similar to specified test fuels used for certification.
Additional maintenance is required and is
covered in Section 03: FUEL SYSTEM of the
maintenance manual.

RECOMMENDED TIRE INFLATION PRESSURE
AT MAXIMUM COLD LOAD
The recommended tire inflation pressures are
given in the applicable documents supplied with
the vehicle. In addition, minimum cold tire
inflation pressures are listed on the Department
of Transport (DOT) certification plate, affixed on
the left wall near the driver’s seat.
CAUTION
These tire pressures are established in
accordance with the maximum allowable load on
each axle. A lower pressure is recommended if
the axle load is less than the above specifications.
