    I've seen a thread on another forum which purports to show an official BMW Recommendation for 2014 (and newer) cars to have a 10000 mile oil change interval. (2014 CBS Intervals - Attachment 5 to SI B000113). I have not yet contacted BMW about this, but has anyone else seen this, or got any useful comments to make.

    There are various oil change intervals specified for the M6 (and M5) which depend on the region into which the car is sold.

    In the UK we get S8KAA which is 24 months or 30,000km. Other options are 24 months/24,000km, 24 months/12,000km, 18 months/15,000km, 12 months/15,000km, 12 months/12,000km and 8 months/12,000km. The intervals are supposedly chosen based on the quality of available fuel, climate etc. however the USA interval was changed from 24 months/24,000km to 12 months 15,000km in late 2014. To me it looks like they set the interval to whatever they think they can get away with, which is why I always get an extra change done at about 9,000 miles.

    I'm not too convinced on the long oil change intervals, for any of the current engines, not just 'M' engines. Evidence is building up that it is a least partly responsible for engine wear (timing chains to be more specific).

    I'm off to the dealers tomorrow for an interim oil change along with the MOT. CBS is showing another 12,000 miles, or another year. Looking at the oil colour, it appears to have a higher impurity (carbon) content for a petrol engine that I'd expect to see. Reading up, I understand DI petrol engines do add more carbon to the oil, so I don't sit too well with another year with the same oil.

    My own N55 engine, (due to the unusual history) has had 3 oil changes already, and only at about 33,700 miles for the interim change tomorrow. Want to keep this engine in tip top condition. (y)

    Hey Richard,

    So how does this align with the condition based servicing countdown that pops up on the dashboard ?

    I am at 9,300 miles and it states, service due in circa 3,300 miles....and I am just about 7 months old.

    Thanks

    The default values are based on quite gentle driving, although the more modern cars have various enhancements like oil quality sensors, I believe that they still just go on fuel used. So, if you know, what's your average MPG over your 9,300 miles? If I extrapolate from mine and the service requirements are the same, I'd guess that you will be averaging about 16.5mpg.

    Hiya Richard,

    Ok noted and makes sense too.

    I'll double check my long term fuel consumption, but I think its somewhere around that figure.

    Cheers

    OK, I've got 11500 on the clock and CBS tells me I'm due an oil change in about 2500 miles. I have a 5 year service pack with this car. If I change the oil now (paying for it myself), is it possible to alter the CBS interval so it pops up again at 20000 ?

    I'm sure it is possible to change the option code for the service interval to one of the shorter options, but I've never seen any reports of people actually doing it. If you have the service pack it would probably cause problems if you did change it. I just keep an eye on it and do an extra oil change mid way between scheduled changes.

    Thanks guys for all your useful comments, much appreciated.

    I can remember the days when 6000 miles was considered a lot before a change of oil and filter. Definitely going to get mine changed fairly soon now...

    Roger, I have asked at my dealership and if I supply the oil they can do an oil and filter change for about £110. So well worth doing an interim change if you feel like it.

    Hey Richard,

    So this is a photo of my trip computer.

    You were pretty good with your guess of 16.5 MPG.

    But I am a bit confused as why it seems to have topped out at 5999 Miles. I have never reset it.

    I reckon my average over all my miles (9300) is closer to your 16.5 MPG figure.

    I presume 6000 miles is its limit then needs to be reset ? IMG-20160627-WA0001.jpg

    I have my Trip Computer set to reset automatically, the OBC keeps the long term data - have a look and see what that says.

    Cheers RIchard.

    I checked OBC yesterday and it seems to just report the information I can see in the instrument cluster under the speedo.

    I reset that after every fuel fill, using the button on the indicator stalk.

    Are their options on the OBC ? I need to RTFM :)

    OBC is designed to be the more long term data, the Trip Computer - well that's for trips! The auto reset option causes them to reset if the ignition is off for more than about 2 hours, or you can reset them manually, all the Trip Computer values reset together.

    Ok got it thanks !

    Its a shame because I always like to see my average mpg over a full tank of fuel. I have been doing this by resetting the OBC every fill up with the BC button on the stalk.

    But I thought it would be nice to also see my lifelong MPG stored somewhere too ! So it seems the trip computer, if set not to reset ever, will run upto 6000 miles. So I have missed data on my last 3300 miles it seems.

    I suppose I'll just have to see what mpg I am getting over every 6000 miles now.

    its true about oil quality sensors, and it makes sense for manufacturers to go that way rather than the "guess work" involved in miles covered.
    mine has this and i had an oil change, at the next intermediate service (prob 3k miles after) they will not change the oil because it will not require it until the oil quality sensor says so.
