Fuel System 53
Diesel Fuel Specification
Quality
Fuel quality is an important factor in
obtaining satisfactory engine performance,
long engine life and acceptable exhaust
emission levels. Volvo engines are designed
to operate on most diesel fuels commercially
available today. Volvo Trucks North
America, Inc. recommends the use of diesel
oil fuel which meets the specification ASTM
D975 (grades No. 2–D and No. 1–D).
Note: The use of lighter fuels (grade No.
1–D) can reduce fuel economy.
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.
Note: When draining the fuel tank, collect
the waste in a fuel proof container. Take the
drained fuel and water to a recycle or waste
management center.
Open the drain at the bottom of the fuel tank
approximately every 30,000 miles
(50,000 km) or 300 hours, to drain off any
water and/or sediment.
Yearly or at 120,000 miles (200,000 km),
tighten all fuel tank mountings and brackets.
Check all hoses, pipes and lines to and from
the fuel tank. At the same time, inspect tank
and connections for any signs of leakage.
Make sure that hoses and lines are not resting
on or touching shafts, couplings, hot surfaces
or sharp areas. Since all machinery vibrates
and moves to a certain extent, clamps and
ties can fatigue with age. Inspect fasteners
frequently and tighten or replace them as
necessary.
