I know this subject has been flogged to death in various forums etc. My car has been serviced all it's life by BMW main dealers. meaning presumably, that they have used BM's recommended lubricants. The car is a '94 525i. BTW. With no apparent oil consumption.
The HB lists CCMC-G4 or CCMC-G4/PD2 as the preferred engine oil, with API SG, API SG//CD, API SG/CE, API-SH/CD, or API SH/CE, also permitted. I'd like to know what these specs mean in plain english. :-)
I'm having the car serviced by my oft used tuning mechanic, and would like to continue using oil of a similar spec to that already in it, so I'd either buy the oil, or tell him what to use.
I,e. Is it straight, semi synthetic, fully synthetic, and what viscosity?
I know I could just use Mobil 1 and be done with it, but I'd like to know the spec that BM use, and recommend. Mike.
