Volvo Penta Service

Changed oil quality recommendation for S-drives
130S-A, 130S-B, 130SR-A, 130SR-B, 150S-A, 150S-B, 150SR-A, 150SR-B
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.
