    Default Sudden MPG loss on Dual Carriageway

    Hi All,

    Need a little help to figure out a problem!!

    I had my car serviced 2 days ago. With this the MPG had become less than what it had used to (53mpg ave down to 47mpg) and not get any better. It had the EGR cleaned, fuel filter replaced and fuel conditioned added. This had then led the MPG to rise back to 53mpg ave on my journeys to work so was happy as larry with that.

    Driving home last night i was cruising at 65mph on cruise control and ave trip was saying 53.1 then all of a sudden MPG dropped to 43 on Dual Carrigeway and dropped to 40 by time got home. No loss of power and boosted fine with no smoke coming out of the back, just that it was apparantley drinking diesel quicker than i can drink beer!!!

    Went out agin in it last night and ave mpg rose to 43 on a light run round and up to 45 on run to work!!

    Anyone have anyideas as very concerned!!!

    Thanks

    What engine model/year is it? And is your car an automatic or manual, hatchback or estate?

    I know that's a lot of questions but it will help to work out if the car has a DPF or not. If it does they tend to drink diesel when it's doing a re-gen. Did you have any lights on on the dashboard?

    Diesel Particulate Filter.

    From what i know...

    It stores some of the crap in a box in the exhaust and then does a regen whereby it burns it off, will smoke a bit more and uses more fuel from what i understand of it.

    Id wait for someone to confirm or deny this though!

    Sounds like a re-gen to me too, Mine did one last week, did 30 mpg for a good 20 minutes, with plenty of smoke too!! You could, if you have access to op-com or similar, look at the distance since last re-gen and see if it tallys roughly with the reading of your odometer.

    If it was on a regen it will stop it as soon as you turn the key off. One way to tell is stop, and whilst its ticking over check the inst mpg on the fuel comp. If its showing a much higher reading than normal 1gph etc then its on a regen. Its always best to let it finish its cycle too.

    Do a bit of reading on diesel particulate filters too
    Now I need a turbo to keep up!
