Does anyone have the current list of approved oils for the Flexible
Service System FSS? My list is dated October 2000 and has eight oils.
Only one of them, Castrol syntec 5w-50, is suitable for Wisconsin
(temperatures below -4 deg. F) and is readily available.
I am told that the current list is longer.
I would like to find one oil for my three cars: MB C230, BMW 323,
The prius requires 5-30 and the BMW preferred oil is 5-30. The only
5-30's on my MB approved list are Castrol TXT Softec plus and Shell
Helix Ultra. I have found no source for these in the Milwaukee area.
