复。4000公里换油后，7600公里再检查化验，发现机油里柴油含量达到了7%
http://www.mazdas247.com/forum/showthread.php?123823449-North-A
I am in Australia and have owned a CX5 Diesel auto since July. The car has
had oil changes at 2800, 4000 and 7600 kms. A Mazda Aust enginer looked at
my car and took an oil sample at 4000 kms. He said that it only had 1% of
diesel in the sump oil and no metal. At 7600 I asked the Mazda dealership (
service) to take samples for me and they were tested by an independant
laboratory (Caltest of Caltex). Their report stated that the diesel in the
sump oil was around 7% and was 'severe'. I have passed this onto Mazda
Australia.
New diesels usually get active and passive regenerations of their DPF (
diesel particulate filter). I noticed that my car had an active regeneration
at 8020 ks.. I then drove 300 kms in 5th gear at 2500 revs, on a 34C (93 F)
on a quiet 4 lane highway, with the airconditioner on. At that 'magical'
200kms it went into active regeneration. The speed, revs and heat in the DPF
did not result in a passive regeneration.
No wonder my sump is filling up with active regenerations every 200kms (DPF
45% full?) and potentially no passive regens. A bit of research revealed
that possibly up to 10% of Aust CX5s are suffering from the fault.
I'm old and this is my retirement car. However I can't take it to places in
Australia that I won't to go to because of the oil issue. Internet research
has shown this has been an issue before April - but I was not informed of
this known potential fault and the car was delivered not fit for purpose.
Long term? I think that a new dipstick and an ecu reporgram won't fully
address the issue. The other problem is diluted oil in the sump and its
impact on engine logevity. It is not only my car but all of the 2.2 liter
diesel engines out there. I have put the info to Mazda Australia and wait
for their response.
Is there anyone who can clarify passive regeneations in CX5s?

Hi - bought a diesel CX5 in July 2012. I had oil changes at 2800, 4000, 7800
and an early 10k service at 8700 so I could drive it 2k without worrying.
Had a PCM reprogram at 11700klms. Now done 17370klms and the oil growth is
OK. A long 3000 Klms trip saw no measurable oil growth. I am having the oil
tested every oil change and so far it is OK.
Mazda worldwide is studiously trying to avoid the issue - even when it is
fixed by the reprogram. It seems to be a tactic by all the car companies.
That is avoiding discussions on Facebook et al. However Mazda Aust was good
in direct discussion. Oh - I also posted questions on the Japanese Facebook
site in Japanese. No response.
Have you had the reprogram of the PCM yet? We are the beta testers for what
I think is a brilliant car. Mazda was and is concerned that public
discussion will impact on their sales - and it will.

发帖数: 1008 | 9 我也觉得应该再观望几年，虽然这个柴油机的技术指标很牛，2.2L 4缸机相当于6缸柴
油机的动力。

解决了，后来卖的批次和mazda6 diesel都没有再发现新的问题。倒是mazda6上面的i-
Eloop（刹车能量回收系统）出了问题，现在全球停止delivery，直到问题解决为止。
不过目前看来这些问题都无法撼动mazda在澳洲的老大地位。
