i can get 50 miles per 1/8 of tank reading on mine but thats fannying about with country roads, drove to gatwick and back on saturday from Ipswich and did it out 1.3 of a tank, 70mph, sensible me...but then i get the urge to pull past every gary boy in the village as they as they come on to the A12 in the mornings and evenings in their Saxos and Corsas
34MPG if im being good and seeing that i think its a 55ltr tank its not bad
18MPG when im being a a menace to the chavs
...no mods yet either but get remapped and i hear you can add another 10MPG...dont know if this is true though
