The "new" since 14 BMW Water Cooled Boxer (1200 CC) which now also shares it's oil with it's gear box calls for 5W40 MA2. BMW switched suppliers from Castrol to Shell, and recommends their BMW label "Advantec" concocted from natural Gas @ $16/litre.
Hardly any UOAs on WC boxers, so what would you guys recommend other than BMW oil?
Thanks
