2016 Mazda 3 skyactive 1.5 d
Short answer is YES, but...Mine's doing the same thing. Oil gets contaminated (rise to "x" mark) in about 3000km.
Regen happens every 80-100 km - this is one of the problems
Other problem is: while regenerating, instant fuel consumption "sky rocketing" - if I drive on highway at 120km/h and instant fuel consumptions is around 6 l/100km - regen starts and it jumps to 18-20 l/100km (for 20 min or 30 km). If I drive in the city while regen is in progress, then starting off a traffic lights get instant fuel consumption to 80 l/100km (RPM kept under 2500).
Can someone confirm what would be normal behavior on this conditions?
When DPF regen is on, you should get hi fuel consumption. But regeneration shouldn't be so often!
Actually, with my 1,5 skyactive diesel 55.000 km engine , I have the same (copy paste) issue! Last week I had my oil and filter changed after 3000 km- X level reached again for the second time in last 2-3 month's !!! Last 30 days I get regeneration every day!!! Every day!!! Last week I was on 40km highway trip - had DPF regeneration in both directions!!! Two times that day...
So in my case, regeneration gets at every 20-30km. I guess that I am holding some kind of 'DPF regen record' at this forum
So...I called official Mazda service...again, scheduled service for front brake pads replacement, and informed them about this issue.
Last time, when I had oil change after 3000 km, they told me 'This is normal...city driving...you must drive your car at highway occasionally...' Every week I have this ~80km highway ride, so their argument is a BS.
Last week, when I told them about my DPF regeneration and oil level rising, the answer was ' in that case, if it's all true what you are saying - you have a problem'... Well no way Mr. Sherlock Holms!!!
And procedure for my next Wednesday service visit, according to them is this:
-make diagnostics, what ever fault value is shown-they send it to Austria Mazda central, and then wait for suggestion what should be done?!? It could be 1-2 week for my car to stay at service...and price...who knows.
Then I asked them, ok... as far as I understand the issues with this diesel Mazda 'revolutionary diesel engine' we have 3 potential problems: DPF, EGR and Injectors? What you think, where is the problem? They told me that, probably there is a problem with injectors, but they will 'check everything'...
So, if I ever finish with this adventure, a will inform you.
