Wow, that's expensive to fill up. Apologies CJ_RR, but I've searched the forum and couldn't find the answer. I only do 25 miles a day on a mixture of speed limits so not sure it's going to be very fuel efficient, I often sit in a bit of traffic dependant on when I leave work. What would I be looking to get if I do speed limits from 30-40 and 60-70?
