Hi all , had my antara 4wd 63 plate a couple of months now and loving it. I have just under a 1000 miles on the clock now and I noticed my mpg clock was going all over the place on the motorway My mpg prior to this was avg 37 mpg it's now dropped to 32mpg if I had not noticed this I would be none the wiser so my question is have I had my first regan?
