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.
