Ive just bought a 3.9V8 disco and the fuel economy is shocking, i got 100 miles out of £60 and that was driving slowly.

Can anyone advise me of where to investigate first as something is clearly wrong.
 
By my quick math that's about 10mpg your getting if you only got 100 miles from £60. Whats the official figures say on a combined 19 mpg?? You have to factor in the age of the V8 as well but that's s bit low.

Did you check for a puddle on the floor when you filled up? :) Sounds like a problem somewhere?
 
Dont know anything about v8,s but does the car have a lambda sensor ? If they are not working it will cause all sorts of fuelling problems and low mpg.
 
ouch I get 100miles from £20 in my 300tdi

has it had a good service? plugs filters and ht leads checked
 
Sometimes it's just happens that way. Mines a lightweight with RR chassis, 3.5v8 with autobox and I only get 9mpg but I do have a heavy right foot because I love the sound of it
 
cheers guys.... it has 33" wheels which proberly doesnt help, oh well, does sound awsome though!!

SMILES per gallon, not miles per gallon!
