I thought the M Series engines were meant to run on Super?



The handbook says one will get more power and mpg from super but the
minimum RON is 95. Until recently all I could get around here was 97
and it still pinked. 99 from tescos works well but it still backfires
when cold. All "perfectly normal".

Have you taken it up direct with BMW GB - by letter or fax?

I'd not take the word of any UK BMW dealer - crooks, the lot of them.
