Best/Recommended Oil

Hi all,

Just wondering what the best or recommended oil is for a 197 and the best place to buy it from? Checked my level tonight and its hovering above the minimum mark so will be due a top up soon.

Thanks.
 
I've always used the Elf fully-synthetic stuff that was in the car from new. Never had any issues and it's not too expensive from the dealers, around £11 for a litre top-up bottle and is always available if I need some at short notice.
