Bascially i have a 1.2 16V extreme. Its a 52 plate and when looking on the internet it says you get up for 47MPG and i'm like . I have no idea to get anywhere near as close as this! I reset my trip computer and i've been driving at 39.1 MPG I used to change gear at liek 1800 rev then found out it was tough on my engine so i increased it to 2200 revs, haven't gone over 80 when been on motorways since i reset it doesn't do much help.
Any ideas?
