I appreciate I'm probably the dullest person on the forum for suggesting it but I very nearly got the magic 50mpg for the stretch of M6 50mph limit jct 10-13ish. It would be interesting to see what others get for that consistent stretch. That's a lardy 07 221, surely I'll see some magical figures from newer kit. Face it, you have nothing more interesting to do on the m6. The merc was on shell premium diesel... I haven't quite figured out if it's % better against % price but I'm seeing numbers over never seen.
