1989 Volvo 740
Viscosity (stable ambient temperatures):
SAE 15W/40 is recommended for use in driving conditions that raise oil temperature and increase oil consumption i.e., mountain driving,
trailer towing.
NOTE: SAE 15W/40 must not be used at low ambient temperatures; see viscosity chart.
Volvo recommends the use of energy-conserving oils. When using these oils, the Volvo recommended oil-change intervals must be
followed.
Synthetic or semisynthetic oils may be used if their specifications comply with the oil quality requirements.
Volvo does not recommend additional oil additives, as they can adversely affect the engine.
Changing oil and oil filter
Oil and oil filter are first changed at the 600-1,200 mile (1,000-2,000 km) service. Thereafter, changes should be made as specified by this
table:
If driving conditions include:
Then the correct oil/oil filter change interval
is:
●
Extended periods of idling and/or low-speed operation
●
Frequent short trips (less than 7 miles = 11 km)
●
Extended periods of driving in dusty and/or sandy
areas
●
Trailer towing
●
Driving mountainous areas
5,000 miles = 8,000 km
or EVERY 3 MONTHS
WHICHEVER COMES FIRST
●
Primarily highway driving
●
Frequent trips of longer than 7 miles = 11 km
5,000 miles = 8,000 km
or EVERY 6 MONTHS
WHICHEVER COMES FIRST
American Petroleum Institute (API) label. This label certifies that the oil conforms to the applicable standards and specifications of the API.

Torque exhaust manifold nuts
The manifold nuts should be torqued at the 600-1,200 mile (1,000-2,000 km) inspection. A loose manifold could alter air/fuel ratio and
cause an increase in emissions and/or poor driveability.
Valves
The valve clearance should be checked and, if necessary, adjusted every 30,000 miles (48,000 km). This does not apply to the 740 GLE (B
234 F engine).
