Whilst we wait for someone who has a more in-depth knowledge to contribute, my experience of the Sky-Activ D is that the DPF is just one thing to be aware of with the 6. They seem to be much like any other diesel in that it will of course play up if the car does not see the right kind of usage to regenerate it as required.
IME, the larger issue is carbon build-up within the engine, I have a 2013 which had some work to the cams previous to me owning it to clear carbon and has just had a carbon clean at Mazda under goodwill due to carbon buildup on the intake manifold, the EGR cooler was also replaced a few months ago for the same reason.
Head gaskets going seems to be a reasonably common issue but I have not experienced this.
Really nice cars but definitely one to buy with due diligence.

I've got a 2013 Mazda 6 diesel. No issues at all, the Mazda guide for regeneration on these is on the website. It says:
"After the engine has sufficiently warmed up (engine coolant temperature of 80 °C or more), depress the accelerator pedal and drive the vehicle at a speed of 20 km/h or more for about 15 to 20 minutes to eliminate the PM."
No more motorways in 5th or 4th required. Mine spends a lot of time in stop start traffic and I've never had an issue yet.

How are you finding the paintwork quality on these 2013 onwards 6's?
I liked the previous 6 (petrol) for it's practicality and esp the ones with leathers and Bose but their penchant for rust (Mazda's generally of that era) puts me right off.
I don’t think rust will be as bad an issue as it was with Mazdas of the noughties etc. WRT paint, Soul Red is terribly soft and chips very easily, others may be similar.I liked the previous 6 (petrol) for it's practicality and esp the ones with leathers and Bose but their penchant for rust (Mazda's generally of that era) puts me right off.
I had a 2014 Mazda 6 estate. Got a great deal on a new one and planned to keep it a good while. Sold it after 42 months....no issues with engine (very rarely did short journeys though).... paint poor and metal very suceptable to dents..... zip confidence it wouldn't start rusting pretty quick.
I was looking at this one but seems to be getting pricey now

I'd expect that to go around the 5k mark. I bought my 2013 for £5125 delivered about 8 months ago, admittedly with higher miles on. There's a good selection of Sport-Nav's on Autotrader for around the same money with various mileages on. I'd check there myself. https://www.ebay.co.uk/itm/283779328827
I bought a 2017 Sport Nav 6 months or so ago and it's been fine enough since then. I would echo other comments about the paint though - it does seem to have an inordinate number of chips compared to other cars I've owned, however I obviously have no idea what the previous owners did to it. It doesn't really bother me much though.
I notice that one seems to have some fairly large chips on the nose and the bonnet gap looks uneven. Could just be the photos of course.

Paintwork aside how are the petrols rated? I'd assume solid engines if maybe a bit flat on torque and needed to be ragged silly to make good progress?
I still have a soft spot for the older shape 6 that was discontinued circa 2011/12, practical, reliable and petrol engines seemed to be able to do silly mileages if maintained.

Ive got a 3 in Soul Red - got about 3 extremely small chips from stones, and I do 25k a year. Paints no worse than any other car, and its not rusting at all
From memory, depending on the colour of the car, some Mazda paint is only two coats, while some have three coats of paint. I can’t remember if the soul red was one of those, but may explain why some owners have no issues and some do.Nickp82 said:

There are two weaknesses affecting Mazda 2.2D engines fitted in a number of models over the last 10 years.IME, the larger issue is carbon build-up within the engine, I have a 2013 which had some work to the cams previous to me owning it to clear carbon and has just had a carbon clean at Mazda under goodwill due to carbon buildup on the intake manifold, the EGR cooler was also replaced a few months ago for the same reason.

Interrupted DPF regens dumping fuel into the engine oil. This can be mitigated by keeping an eye on oil levels and my doing regular oil changes...certainly more frequently that the 12,500 miles on the service schedule.
Leaking injector seals. This is a less well known issue and potentially catastrophic. There is a common problem that the injector seals (copper washers) fail causing combustion gases to enter the engine causing a carbon build up in the oil. In time the debris collects in the sump and blocks the strainer that sits before the oil pump pick up pipe. This causes oil starvation to the engine and subsequent seizing of the engine and a £8,000 repair bill. This problem can happen regardless of oil change history. I believe Mazda have now added the replacement of the injector seals as part of the 75k service (there is also a recall to check torque), however, the problem can occur at significantly lower miles. I would recommend anyone with a diesel Mazda to get the seals replaced asap, cost should be a couple of hours labour plus £5 for the parts, an inspection of the strainer would also be a good idea.

My GJ has some scratches to the paint (Stormy Blue?) that appear to have been caused by a cat but no stone chips that I've noticed. That's on a 2013 155k car used mostly on motorways.

I've searched around and those injector problems seem to be the GH model, rather than the GJ. They both use a 2.2 diesel engine but the one in the GJ was totally different to the GH. The 2014 car will definitely be a GJ and shouldn't suffer with these problems.

Nope, it most definitely affects the GJ, ask me how i know My GJ has some scratches to the paint (Stormy Blue?) that appear to have been caused by a cat but no stone chips that I've noticed. That's on a 2013 155k car used mostly on motorways.
I've got a 2009 2.2 GH , lovely car, but just found the joy of timing chain causing the dpf light, cost half the value of the car to sort but running perfect again. I do mainly long runs and still get a lot of regens , and oil was badly diluted on service, so will be doing more regular ones.
Do like the look of the newer one for replacing it as the commute/biking/camping car though, better in every way than the Mondeo
