E63 2008 Fuel Grade Question

[markys]

Does the 2008 E63 require standard unleaded or does it need super unleaded?

[W8aMinute]

The handbook will usually say so. I'm pretty sure the M156 engine has knock sensors so should be able to take advantage of higher octane fuel.

Could put either in my old c63's but it gave better performance on optimax or similar
