I got this info from an American website -

M5 and Z8 Oil Recommendation
M5 (S62 engine) produced up to 3/00:
-- The M5 up to 3/00 production requires a specially formulated synthetic engine oil - Castrol Formula RS SAE 10W-60 or Castrol TWS Motorsport SAE 10W-60 and is the only approved oil for this engine.
-- Castrol Formula RS SAE 10W-60 Synthetic Oil or Castrol TWS Motorsport SAE 10W-60 Synthetic Oil must be used on M5 models produced up to 3/00 whenever a service is necessary to avoid engine damage and is available under BMW part number 07 51 0 009 420 (1 liter bottle).
Notes: For logistical reasons Castrol Formula SAE RS 10W-60 Synthetic Oil has been renamed and is now called Castrol TWS Motorsport SAE 10W-60 Synthetic Oil. Since the formulation has remained the same it is sold under the same BMW part number 07 51 0 009 420.
Only if a customer needs to top up oil between oil changes and Castrol Formula RS 10W-60 Synthetic Oil or Castrol TWS Motorsport SAE 10W-60 Synthetic Oil is not available is it permissible to use synthetic engine oils with a lower viscosity which conform to the API classification SH or higher.
However engine oil consumption will increase when Castrol Formula RS 10W-60 Synthetic Oil or Castrol TWS Motorsport SAE 10W-60 Synthetic is diluted (topped up with other low viscosity synthetic engine oils).

M5 (S62 engine) produced from 3/00 and all Z8: (Need 2000 W plate)
-- The S62 engine incorporates redesigned piston rings from 3/00 which permit the use of BMW High Performance Synthetic Engine Oil SAE 5W-30.
-- The recommended engine oil for all Z8 vehicles and M5 vehicles (produced from 3/00) is BMW High Performance Synthetic Engine Oil SAE 5W-30.
Note: Refer to Service Information bulletin 11 04 00 for S62 engine oil level checking procedure.


Does this apply to UK M5's as well ? How can I tell exactly what kind of engine a car bought on 30th March 2000 is, cos it could have been made during Feb02 I guess ?
