Hi Guys, Still loving every minute of my Z4! However on turning off the engine tonight an orange/yellow oil lamp light stayed on along with a short beep... I'm guessing this is because my engine oil is low? But wasn't sure as its yellow not red!... On that note what engine oil do you recommend? (mine is a 2008 2.0 litre).. Thanks in advance (I've attached another picture of my baby)
