Volvo Penta Service Bulletin
Group 44-1 Number 85 Version 2 Dated 10-2010, Page 1
Changed oil quality recommendation for S-drives
130S-A, 130S-B, 130SR-A, 130SR-B, 150S-A, 150S-B, 150SR-A, 150SR-B
Volvo Penta has changed the recommendation for oil quality in S-drives.
S-drives manufactured September 2010 onwards will have a sticker with the information “SAE 15 W-40 ONLY” attached in connection to the oil filter. Older drives have a sticker with the text “ATF OIL ONLY.”
Volvo Penta recommends that all S-drives change from ATF oil to engine oil SAE 15W-40 at next oil change.
It is possible to replace oil without laying up the boat, please refer to the Operator’s Manual. However, with this method some ATF oil will remain in the stern drive.
For problems concerning sliding/delayed engagement Volvo Penta recommend change of disk package and replacing the oil with engine oil SAE 15W-40.
