What oil are people using for their M4?

[x5x3]

my "please top up oil" message has just come one with less than perfect timing!

I don't desperately need my car at the moment (as in I don't need to travel for essential business) so plan to order some from Amazon and be patient as it will not be a priority delivery.

So what are people using?

Opie Oils has a decent look-up system. Halfords (for all their faults) are still running a mail order business.

Your manual will tell you, just use the one it recommends.
