Engine Oil Rise

[Morsa]

Hi.

We have done many test in the spanish forum and we are certainly quite confused. Can't find a regular patron of behavior in this issue.
For instance, users like nicknamed Bombur had his oil at the X and changed at 10000 km, no other action, recently has done his 20000 regular service oil change, the oil hadn't move one mm, he did not alter his driving habits. Dealer don't change the dipstick even this time, still with "A".
Another user, husky72, again oil at X changed about 4600, remap applied, he reports faster oil rise than before.

Between this two "extreme" cases there are many with very distinct behavior, regions, fuel use etc...which have the problem. Others not.

I think your points 1 and 4 may have influence coupled to the bad management of regenerations. The #2 is doubtful because the problem is present in so many countries and different drivers. The #3 may have been small impact in the begining, but the difficulty is not so big to hide an oil at the X and today every impacted driver is an expert in Mazda dipsticks use.

Hi all,

Could it be due to defects during the manufactoring process?

Any feedback on oil rise of CX-5 diesel 2013 builds?

 

[WNJ]

I was told the oil level fluctuates during use based on the dpf and regens... high oil level is a sign that a dpf regen is due and the oil level will lower again once that has occurred. That and the majority of 'issues' with high oil levels people are reporting are due to misreading the dipstick / not following the correct procedure to measure the oil level, it isn't a simple as clear the stick, put it back in, take out and look at the level. I have nearly 20,000 miles on the clock in 8months, the car runs fine so I don't see the point in getting worked up and worrying about something that's probably just all hype and no fact. Enjoy your car, IF there is a real issue, Mazda will have to sort it out as am sure they wouldn't want any bad press from keeping it a secret!

 

[alex1706]

Mine has risen to half way between the upper mark & the X.

Quite honestly like the posting above this one, (WNJ) no point in getting worked up about it.. Certainly not an issue to lose sleep over.

If there transpires to be an issue, it will get sorted. Mazda seem to be aware, and we have a 3 year warranty. Although I rarely keep a car longer than 3 years.

As the guy said, enjoy your car.

HI,
after receiving the software version 83.04 and a free oilchange at 1500 km, i went for a trip about 1500 km long-80% autobahn 10% country roads 10% city.
At the beginning oil level COLD Engine (oil quantity 4.9 liters) oil level excatly Maximum with dipstick type B!
Returning - oil level COLD Engine excately Maximum again!!
No oil rise to be notified!
Should Software Version 83.04 be the antidote for the engine oil rise????

How do you display the Software Version?

 

[Chevyfredi]

This software version is only for the Mazda CX 5 with a 2.2 Litre DIESEL ENGINE!!

 

[Morsa]

Very good news. Now we have to check if the SW is the same in all countries

Hi chevyfredi ( alias stone... (shady)),

it is a little bit different.
83.04 is the current version of the IDS (Integrated Diagnostic Software) as a part of the Mazda Modular Diagnostic System.

If necessary central service organisation is putting actual changes for ecu sw or parameter sets etc. to a new IDS update package with an own version number.
This package may contain updates for several ecus, may be for several car types or not. ( 6, 3, CX-5, MX-5 etc.)

Service is asked to check on a regular base in the network for the avilability of a new IDS version and to download it to the local Laptop PC. ( database)
When a car is connected to IDS it checks if for this specific VIN with the current ecu versions any new item is available. Then it may be actualised.

It is a pitty that even the service people in the maintenance shop don't get the information what is inside the package and for what reason ( No list of changes)

In our case it seems that in the IDS package with version 83.04 there is an update for the CX-5 Diesel PCM-Ecu SW ( Version unknown !?)
Hopefully it is the improvement to the oil rising problem we are waiting for here in Germany.
I am trying to detect the PCM SW version when getting the update.

I am not aware if this system and the IDS packaging is the same for all countries !? I am sure for UK and Germany.


P.S.: I missed that there is also a regular update of the diagnostic database by DVD by a fixed period.:

 

[q50_treiber]

............. here is the current PCM SW Version included in IDS update 83.04 : SH1B 18881P
may last version as a part of IDS 82.04 was : SH1B 18881K


@Morsa: I just checked your Spanish Forum and detected the infos with the "P" version.

Fine, we are all using the same diagnostic version and PCM software is also the same !!
Even without any info from Mazad I believe this should be a SW update intended to improve oil raise.

As posted previously on this site, it is believed that there will be another software update. This is about the number of DPF regenerations. It may have something to do with the pressure differentials between the input and output pressures of the DPF. If this is the case then regens will be less frequent - as occurs in other small Diesel engines - and there should be even less diesel in the sump oil at the 10,000 Klms services.
Maybe we can look forward to engine longevity. I clocked up 547,000 ks in a Subaru 2.2 litre Liberty with nothing breaking in the 12 years I owned it.l

I'm old so I hope the Mazda is just as good.

 

[q50_treiber]

.... I am aware that problem might be solved in several steps as written here.
Up to now still not any statement from Mazda Germany regarding a problem or a solution for that.
So we are just glad to have a some indications that this version might be a first step.

By the way in Germany we have 1 year or 20.000km services. So Mazda's problem should be larger here.

 

[Morsa]

q50, I had planned to inform this forum about the finds of versions but you have advanced me, cool!.

Yes the same IDS versin is confirmed also in Spain 83.04, the guy who told that had one version in his ECO ended by a "G", updated for ne ended by a "P". Thats looks fine.

It seems that in Spain things are running faster than in France were I actually live, I have no news of update from my dealer.

change-man, we all know you have posted here and there..you area very famous indeed, thanks for your reports.
The porb is that in Erurope we need a fix for 20.000 Kms, not 10.000 as q50 said. And most of us are waiting still the first update, so not idea of "another one".

Cheers.

Update from a UK perspective.

After 5,800 miles the oil level has reached the X on the dipstick. As my wife's Mazda 2 was in for a 10,000 mile service I decided to bite the bullet and get an oil change on my CX-5.

Bit disappointed that I need an oil change so soon, but hopefully things will settle, and as mentioned previously, seems to be more of a Winter problem. So should we get two weeks of Summer this year, then perhaps things will even out. Or maybe the software change will be further developed, or even hit the UK. After all Mazda will soon become unpopular if owners start to highlight this additional expense.

I did ask about perhaps either the labour fee or cost of oil be covered by Mazda, but was politely declined. This time I will let it go, but won't be so keen in future.

I did try to plod through all the pages on this thread, but have not been able to find if anyone in the UK has managed to get any concessions from Mazda H.O. If anyone has done so I will be very interested as it may help should I wish to take it further.

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.

I don't mind the fact I had an early oil change, as it gives me peace of mind, I'm an engineer of the old fashioned type and grew up with the concept of replacing the oil in the first 1,000 miles to remove swarf etc.

The oil rising on the dip-stick however, I don't seem able to get any sense in the UK. Any re-programming details or Bulletins don't seem to have been passed onto the UK Dealership, unless anyone knows different.

I am trying to find out if there have been any such cases in the UK that Mazda have agreed upon and accepted that this is fact a recognised issue. A case number or bulletin number (with the actual bulletin available electronically as a PDF File) would be very useful.

I'm afraid your dealer is selling you short. My cx-5 got new 450c dipstick, PCM upgrade and oil change and filter change last week. I had to raise a case with Mazda uk and refer the dealer to them. For info in the uk Mazda are using a new Mobil 1 oil specifically for dpf engines.

I have done over 19,800 miles, oil was changed at first service (12,500miles). Took to garage for a tyre rotation 2 weeks ago, mentioned the oil looked as if had risen since service... was shown a Mazda service bulletin about oil level mis-reads on CX-5 and that's the end of it. They check for recalls or software updates each time I've booked in. That's the end of it, car performance is fine, it's still doing the miles, if theres an actual issue they'd have to do a recall so JUST ENJOY YOUR CAR!!!

Don't worry WNJ I am enjoying the car, and I went for the oil change for peace of mind. The level had just reached the X and at first I was in a bit of denial, but then thought better of it.

Secret is, don't keep looking for trouble by checking the level every day. If I check it too often I shall become paranoid.

My cunning plan is to be mentally prepared should I find this will be an expense every 6,000 miles.

Come 1st Sept car will be 12 months old, covered 12,000 miles & will need a first service, and another oil change, with which I'm happy to accept. By the time I hit 18k in March 2014 hopefully this will not be an issue, whether sorted by natural means, or a Mazda update.

This is about the number of DPF regenerations. It may have something to do with the pressure differentials between the input and output pressures of the DPF. If this is the case then regens will be less frequent - as occurs in other small Diesel engines

I can't see how this would work. Unless they can also reduce the amount of build up in the DPF then less frequent regens would also mean more build up which, in turn, would mean that the actual regen process would take longer to burn off that build up. For me, the regen process already takes around 15km of driving (highway cycle) which is far too long because it means there is always a good chance of having the regen cycle terminated early (ie by arriving at a destination in the middle of a cycle). Making the regens less frequent (but longer in duration) would make this even more likely to happen. I believe that reducing the frequency of regens only makes sense if they also reduce the amount of build up in the DPF.
