Octane rating of fuel

[kelviN]

using 91 on a 95tuned car - one result is VERY poor fuel consumption. drinks like 16L-17L/100km haha. One previous long weekend there was only 91 around =(

^^^ Good point.

But even after putting some 91 in, the next fill will be with 98 will it not?

I would... Sweet as....
