| Message: | | Unfortunately, GM has discontinued OES and just about any Delo or Rotella you can find now is as bad a poison to our vintage BMWs as SM gasoline engine oils due to it's lack of ZDDP!! Please call or email me for the SWEPCO dealer nearest you. SWEPCO's 306 Premium engine oil is unchanged from the last 15 years with 1450ppm ZDDP and will NEVER meet the 2007 API SM specs!! Save, guard and protect your vintage motors, use SWEPCO 306 20/50 or 15/40.
