Quick update on this little car,
Over the last 7168 miles, the average has been 37.83mpg (imp) with a low of 33.72.
MPG's are usually higher when I'm driving- but my more gentle style tends to put the CEL on (usually showing as the Lambda being out of range). I consider this a "leanburn light"
Last weekend she got stock rear suspension fitted, making the ride noticeably more compliant, and allowing for 40psi all round on the tyres.
Lo, and behold on my commute last week she gave 409 miles for 42.27L= 44.02mpg (imp)
Cracking news- so much so, I have her again this week and I'm hoping for another 40+ tank
