Hello,
my oil light came on while standing on a hill today so I have to fill up the oil level a bit. The thing is that we have national holiday here in CZ and BMW dealer will be closed for quite a while. What are the specifications for the standard BMW oil the dealer uses? Can oil brands be mixed if the specifications of the oils are respected?
Many thanks!
