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 15 W -40 oil 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 -30 should not be used under normal operating conditions.
