    DC2R Fuel Consumption

    I recently replaced my fuel filter, o2 sensor, thermostat, replaced oil and filter, change coolant.
    Now I'm still getting the same fuel consumption which is about 300-320 per tank,

    Just wondering if theres any other way to really get more, as a lot of other friends with dc2r's are getting 400+

    Mods:
    -Intake
    -Exhaust b-pipe/muffler
    -Stock Headers

    Petrol: Shell 98 or sometimes 98 BP (i see no difference in fuel economy/driving).

    Not a bad idea, a wideband O2 will tell you if it's running too rich for any reason.

    Sounds like you are running too rich.

    Does the car misfire? Check all ignition components (Spark plugs, leads, dizzy and/or rotor)
    Check Air intake temperature sensor
    Give your throttle body a clean including the IACV
    Check and/or clean injectors. injectors may be leaking?

    sounds about right then see how the fuel consumption is!

    what type of conditions are you driving in?, I get close to 450 out of a tank, with 50/50 town and highway driving. oh and im running on 95 octane, it doesn't seem to like 98

    maybe check your fuel pump regulator is holding the right fuel pressure? and also try clean n flush your injectors

    This is a good thing to do too, have the injectors flow bench tested and serviced if needed =)

    Also be aware that as your engine gets worn down more, the more inefficient it will become.

    check your tyre pressure, refer to door placard, also are your tyres worn out?? if it is, that's probably why your car is drinking fuel much. some people don't look at the tyres as one of the factors to fuel consumption.

    thanks for the replies guys, tired pressures are good and so are the tires, i was under the assumption that using 98 octane cleans the injectors anyways,
