Maintenance
When draining the fuel tank, collect the waste in a fuel safe 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
50 000 km (30,000 miles) or 300 hours, to drain off any water and/or
sediment.
Yearly or at 200 000 km (120,000 miles), 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.
ENGINE OIL
General
Keep the engine oil at the proper level and change it at the recommended
intervals. Always replace the oil filters at the same time as when the oil is
changed.
Oil Quality
Volvo Trucks North America recognizes engine oils that meet or exceed the
standards given by American Petroleum Institute (API) for the oil
classifications listed in this manual. Only oils licensed to carry the API
symbol should be used. Lubricants meeting API standards have provided
maximum engine life when used together with the recommended oil and oil
filter change intervals.
EO-O Premium Plus (or VDS-4) diesel engine oil is mandatory for use in all
2007 emission compliant Volvo engines. Chassis equipped with a 2007
emission compliant engine, which can be identified by the presence of a
Diesel Particulate Filter (DPF), also require the use of Ultra Low Sulfur Diesel
(ULSD) fuel. EO-O Premium Plus oils exceed the new API service category
CJ-4.
