Does it say 91 _RON_? That's what mine says, and it's the regular low-grade
gas here in Europe. I can get 95 (regular) and 98 (super) unleaded here in
Holland.
Owners manual says 95 is OK.

It drives fine on 95. I'm not interested in paying $.10/litre extra for super.

BTW Even though I drive it quite hard sometimes, I seem to get about 10
km/litre. Not bad for a 2.3- My old 80 1.8 used to do the same in
start-stop traffic.

 The function of an expert is not to be more right than other people,
         but to be wrong for more sophisticated reasons.
