E87 118i Engine Oil grade
Hi there,
Wonder if you assist. My 2008 E87 118i FL had an oil change done. The oil used was Castrol Magnetec 10W40. The problem I am having is that at 4000km, there seems to less oil in the engine and I need to top up.
I think this oil is too thin, therefore suspect that the oil is being burnt. The car has 42000km now.
Please advise if 5W40 Castrol Edge would be a better grade of oil.
I do not know what BMW recommends.
any info will be apprecisted.
