Oil quality
Meeting API specification SG, SG/CD, SH or
Energy Conserving (EC) II
For best fuel economy and engine protection,
consult with your authorized Volvo retailer for
recommended oils. Oil with a different quality
rating may not provide adequate engine
protection.
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 prolonged driving in mountainous areas.
Extra oil additives must not be used unless
advised by an authorized Volvo retailer.
NOTE:SAE 15W/40 should only be used in
extreme operating conditions such as trailer
towing in sustained ambient temperatures over
104° F (40° C). However, SAE 10W-30 synthetic
oil would be a better alternative in such
conditions.
SAE 15W-40 should not be used under normal
operating conditions.
