You did an excellent job on obtaining this information.

The last of the links sums up the situation as posted by Tom: -

"Heard something interesting regarding the factory engine oil fill: BMW specifies Castrol SAE 0W30 and PSA specifies TOTAL SAE 5W30. Note that PSA builds the R56 MINI engines.

One can infer from this that SAE 0W30 can be used in the MINI's engine without worry. This should minimize, but not totally eliminate, incidents of cold start noise. However, I recommend you get it in writing from the dealer that use of Castrol 0W30 full synthetic engine oil will not void your engine warranty should you decide to change to SAE 0W30 full synthetic.

It has been mentioned by myself and others in earlier threads that Castrol Edge 0W-30 could reduce occurrence of the 'noise' especially in colder weather, or if the car is parked on a slope.
