Woops, read it as "just as efficient".

Ok so I've put in Shell 91. So far so good, and I can already notice the better fuel economy... based on the fuel gauge I can maintain a higher speed with the same fuel mileage displayed (and over the same route I've done lots and lots of times so I know the parts of it very well)

Can't feel the engine holding back as if I'm running too low octane so hopefully everything is ok. Remember this is with the 93 octane MarkD chip for M50vanos

Either I'm nuts or the car feels a lot smoother too.
