A diesel mileage question

    Its probably an obvious answer...but not to me.

    I'm looking at changing my car, and having always has a petrol I'm looking for a diesel.

    When going for petrol, low mileage has always been important. I got a 3 year old 07 with 31,000 km on the clock and 7 years on still only has 76k.

    My question..
    What should I be looking for as a max mileage (KM) in a 2009/2010 diesel.
    Obvioulsy low is good but a lot of what I see has about 100 - 120 k on the clock.

    I saw this Ceed with 120k . Whats your opinions on it?
    thanks in advance:D

    I'm just curious why you are looking at high mileage diesel cars now as opposed to low mileage petrol cars like you did the past? I know the choice of petrol cars is limited these days but with only putting 45k km in 4 years on your existing car, do you really need a diesel car especially a high mileage one that might require a lot of wear and tear items replaced on it in the near future?

    Thats my question exactly :)

    I know my car is low mileage but need to change it. Its an 07 megane with nct to 2015, serviced twice a year. etc.

    I'm looking for an 09/10 and after selling mine should have about €7-8k to spend. I was looking at diesel as tax and fuel are cheaper and I've only got low mileage at the moment due to being out of work for a while. If I got a low mileage diesel I'd be happy.

    The only diesels I've seen are high mileage. I might be looking in the wrong place!

    What I need is something for a growing family. I've 2 kids now so extra space is needed, hence I was looking at an estate/MPV. I need Isofix for the child seats and I need something reliable.

    If anyone has any suggestions they'd be welcome.
    Thanks

    My point is that you may not warrant the need for a diesel car irrespective of whether you need more space or not. There is more to owning a diesel (especially a high mileage one) than just headline grabbing cheap motor tax and lower prices at the pump. A 120k miles modern diesel car could potentially require a new DPF or DMF in the not so distant future which could cost more than any small savings you make on motor tax or fuel costs doing small journeys. Also if you do a lot of city or short trips then you may encounter other associated problems as diesel cars don't like short stop/start journeys as it's not what they are designed for.

    If it were me doing that small mileage, I'd stick to finding another petrol car.

    Thanks for the advice.
    On that note can you make any suggestions on what I could be looking at in petrol?

    As a side note, your servicing seems excessive. I think you could easily reduce the servicing to once per year.
    The service interval on my petrol Megane was every 18,000 miles (28,000 km) or annually whichever comes first.
    You only put up 45,000km in 4 years, an average of 11,000 km per annum, yet you have your car serviced twice a year.

    I'd suspect a more modern petrol car you get has a similar or longer service interval.

    I'd consider it like that in regards mileage (we are talking km)
    Average diesel will probably need clutch + DMF at about 200k.
    On Irish roads, except if it was used only on motorways, probably at about 200k suspension will need some work.
    Possibly brake discs will need to be changed before 200k, depending on driving style.
    Engine should last easily 400k - 500k without any major work on most cars, but in some cases some problems might arise earlier.
    Turbo might go much earlier due to no appropriate servicing.
    Injectors might get clogged from using not best quality fuel.
    Other things rather deteriorate with age than mileage. Bodywork will get rusty at some stage. Exhaust the same. Electrical problems are more likely to happen on older car. They are seldom linked to high mileage (f.e. I'd expect to have electrical problems more on 8 year old car with 30k km, then 5 year old with 600k km).

    Considering small mileage you do, I wouldn't think about diesel.

    I agree with you 100% I did the whole diesel thing while only barely doing 7000 km's a year firstly in an 02 Octavia and then in an 07 Octavia both 1.9 TDI's. Unfortunately I never got up enough years to even enjoy the cheap tax... I'm driving a 09 1.4 TSI dsg Octavia now and I love it. I only have it six weeks and find that I'm getting 600-650Km's to the tank of petrol where I was getting a maximum of 700-720Km's from the diesel. The petrol car is so much smoother and quieter and is €390 a year to tax compared to €670 for the 07 Diesel. I changed to the petrol when my mechanic diagnosed the increasing moments of total power loss(limp home)were being caused by sticking vanes in the vnt turbo causing overboost. He also thought the clutch was starting to feel very juddery. Both jobs realistically were going to cost the guts of 2,000 yo yo's. I talked nice to the CU and got rid of it. In fairness it is a brilliant car for a driver doing the proper diesel driving. Unless my weekly driving changes dramatically I'm a dedicated petrol head from now on.:D

    You must of been doing seriously short trips or driving the rag out of the diesel Octavia's. I have my parents 05 octavia this week as they have my focus there's almost 550km on the tank and the gauge is sitting at 1/2 tank that one is normally good for 900km before the light comes on and the newer 11 one they have will do 1000-1100 km before the light comes on. But I would agree diesel are absolutely pointless unless your doing fairly long trips and not all town driving. The annual mileage isn't as important it's more so the type of driving you do but obviously it's all linked.

    Low annual mileage doesn't necesserily mean short-trips only.
    I know people who work not far from home, and they virtually don't use their cars Monday-Friday, but then do 300km trip every weekend.
    Car will have very low annual mileage, but it's not short trips. For that kind of use diesel is suitable, however probably not necceary.

    Very short trips mostly. I did crack the 1000 Km's to the tank once, while going from wexford to letterkenny and back. They're a great car but to get the best out of them you really need to be doing the mileage/ correct type of journey. When it started going into limp mode the fuel mileage fell dramatically 645 Km from the last tank of diesel:(

    Good point. It was often 6 weeks before my car ever left the town.... Not good for the aul diesel.

    That can be countered with petrols are cheaper to buy and less to go wrong. What is your annual mileage?
