No, I was there for a family wedding.
So I had an interesting drive back, I was aiming for 500 miles to a tank. Bearing in mind I have new pads, discs, shocks and other bits in the boot, I chickened out at 485. The light was coming on for a minute or two and then going off and I didn't know when the next services would be. I could of gone on knowing the distances now. I think 550 would be possible at a push, I wasn't going particularly slow either speed between 60-75mph and kept the eco light on for 95% of the time.
With a quick calculation it's around 49/50mpg which I think is pretty good.
