    Please tell me this is wrong and there's a fix

    Plain and simple
    1999 2.4 lpt c70 me7 auto

    £30 in tank
    Regular driving 64.2 mile return from it
    That can't be right
    C70 2.4 T Saffy Pearl now dead and stripped
    850 T5 "the Turk" wagon
    V70 D5 parked up for sale
    V50 1.8s family wagon

    That's about 12 - 15mpg judging by my own consumption of about £12 - £15 a day return to get to work and I do around 25 mpg for that.

    £1.40 per ltr unleaded super £28 would get 20 ltrs, which is 4.44 gallons, so if your doing 20 mpg that will get you aprox 85 miles, id say summit is wrong

    I'd say you have a leak,

    Check, Injector seals, Fuel pressure regulator under the rail, Fuel filter under car they can rust through, Fuel tank pipes, filler neck (metal clamp) can rot through. Vac leak on the manifold Purge valve from charcoal cansiter, canister itself. fuel return hose/vacum to tank. condition of the plugs. Stupid question is the auto box getting into top gear?

    Injector refurb, perhaps you have a MAF fault or another sensor so the engine is over fuelling. A session on Vida might be useful!

    My manual C70 me7 T5 gives me upto 35mpg, and never less than 28-30 even when driven sportingly. Can't see the auto making such a big difference.

    even tho it might not be throwing a cel light, read the codes. Also might be worth looking at changing the fuel filter

    O2 sensors do play havock with economy but if it's that low is say a leak somewhere.

    i would change the thermostat and sensor in the housing.
    if the gauge is low, that sensor does the guage and ecu so it could effect fuelling.

    Try a piece of cardboard down the front of the radiator, cheaper than a thermostat

    well it was meant in jest. I did the same for years with my 440 in Norway. It does help with warm up so will improve the mpg until the 'stat is replaced if that is the problem
