This is bit crazy week, I have to do quite few miles on road. Now most recent tank was bit less than previous one, might be because of my right foot too, but still over 64mpg, that is quite good for such car as ZX, front airdam is doing miraclous things it seems, it can't be that there would be error in two fillups and as I managed to get a lot further than before airdam with a tank, I can only point airdam being one responsible from better FE.
That is almost 10mpg change that has happened after I did install airdam, it is quite a lot, imo. might be that it is partly because maybe I have just adjusted to mods, like wheel skirts and kamm + now airdam.
Will see more results by end of a week.
