Cooling System - Volvo 262 Owner's Manual

1977 Volvo 262 264 265
At temperatures below 0°F, multigrade oil SAE 5W-20 or SAE 5W-30 is recommended. However, this
oil should not be used when the temperature is continuously above 32°F.
Driving under adverse conditions such as high ambient temperatures, trailer pulling, hill climbing,
driving long distances at high speeds, extended periods of idling, low speed operation, short trip
operation at freezing temperatures may require oil and filter changes more frequently (every third
month).
Drain the oil after driving while it is still hot.
Changing oil filter
Replace the oil filter at every oil change. If the oil filter is changed separately, 1/2 qt. of oil should be
added.
