Is it only me?I have tried to find engine oil to the spec in the PlusFour handbook but I am confused by the amount of 5w30 oils available but none as per the handbook. What is everyone else using? Thanks in advance.

It should be API SP which was designed to reduce the chances of low speed pre-ignition - LSPI which is an issue with turbo-charged engines. Its should also have a medium ash content due to the CAT. Fully synthetic is also a requirement due to the high temps in the turbo. BMW also recommend an LL spec oil. Put all this together and you end up with Castol Edge ( the API SP version which is a later spec) or Motul 8100 eco-clean 0w-30, both of these are used by at least one dealer I spoke to. I believe the factory use a Miller oil but I dont know what the precise spec is. Frequent oil changes are probably more important that the spec as BMW have a habit of leaving the oil in too long! Good luck!

Indeed, manual states 0W30 full synthetic.
As a retired Shell employee, I insist my dealer uses Shell oil… point is that the oil meets the proper requirements.
