Its no good!¬ I couldn't wait!
got to 207 miles and saw a good ish offer on dino, so had to fill up. Normally top up when gone 200-250 miles so at least its a direct comparison. My last fill up was spot on my avg, 26.5mpg(imp). My journey is mostly crap, stop start urban stuff, dont get into 5th much, but after 207 miles the gauge looked to be in a slightly diff place. well it worked out to be.............bearing in mind its only10 miles each way, plus stop start running about,.........28.9mpg
i think thats a 9% increase, so room for improvement, but a good starter. I was worried it was only going to be 27mpg in which case I'd have been well miffed. worked out that I saved about £4.17 on half a tank, so say £8.0 a tank, plus my saving using svo, lifes good
