1996 Volvo 850
Do not use oils with other viscosity ratings. The use of incorrect viscosity oil can shorten engine life.
Volvo recommends the use of energy-conserving oils. Look for the API label. Synthetic oils complying
with oil quality requirements are recommended for: Driving in areas of sustained temperature extremes
(hot or cold), when towing a trailer over long distances or for a prolonged driving in mountainous areas.
Extra oil additives must not be used unless advised by an authorized Volvo retailer.
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.
Changing oil and oil filter
Oil and oil filter changes should be made as specified in the following table:
If driving conditions include:

WHICHEVER COMES FIRST
EVERY
