Are US Dealers using 0W-30 or 5W30 on LCI M5s?
I read that UK dealers have switched to 0W-30 for the M5. They were using 5W-30 previously.
Does anyone know if the US dealers have done the same or are we still getting the unwanted 5W-30 oil like we did on the 2013 cars?
I'm doing break-in service later this week, so I need to know whether to buy 9 bottles of 0W-30.
