Got myself a new van guys, a vw caddy 104ps jobby, its quite nippy i suppose for a van and has all the mod cons lolo, kind of like a car to drive tbh, anyway set the mileage thingy, filled up with £70 worth of diesel

and got 455 miles and the fuel light was on ?? just normal driving really 70mph etc etc and around town alot
Is this any good ?? i cant really remember if my old vaux combo was much better tbh?
And if i chip it will i get better economy ?
