Oil Level Again
« on: August 15, 2019, 06:27:13 pm »
2009 2.2 MZR-CD 185hp

Oil level rising from low to high (not x) within 2000 miles

Injector copper washers checked, no signs of leaks but replaced with new
New DPF fitted
No faults showing up on Forscan, as far as I can see its all ok
New cam chain kit fitted a while ago and still reading well within tolerance

I think I must be missing something obvious,

Any suggestions from all your collective knowledge would be greatly appreciated

Steve

First I think you should not only put oil that reaches the low. It should be on full.

Second this is how the regenerations work. You should not count the level increase by miles because it may be misleading.

For example, doing a lot of short journeys with very little fuel in the tank, and then fueling and going for a longer drive. The car will do a huge regeneration.

Your concern would be whether it goes from full to X. At the moment it sounds very normal.

Lastly, you may want to check the injectors as a whole, not just the washer but also the rubber and silicon seals.

When I change the oil I always fill to between low and middle on dipstick,That is the useable range, I have had the sump off a couple of time to check oil pick up for debris, and it is always clean.
I dont do short journeys, I go to work on a Monday morn with a full tank, and drive 120 miles, 50 of which is at about 80 mph, and the rest is not hanging about.
Then return at the end of the week.
Are the rubbers and seals prone to leaking

You may find that the level increases but it is not a linear increase. Just keep an eye for it. You may do the next 2K miles with no increase.

Yes there are YouTube videos from companies advertising the tools and the rubber and teflon seals as a set. So you could replace them.

Gary,
You are putting the correct amount of oil in your engine. I was told by my SM to put 5.1 litres  in . I have the 2013/4  model. It doesn't want to be on the full mark on this engine it will reach there soon enough.

 2013  6 Skyactiv 2.2d    33k miles, bought with 10k on the clock, 18months ago.
First 'failure' at 18k, red light low oil press .
Of course it was high  'oil' level, towed away, oil changed under warranty.
Second failure avoided at 24k by annual service oil change.
Third failure avoided at  29k  by me changing oil.
Fourth failure avoided by Mazda changing oil at 34k.
All this blamed on my driving style by Mazda Head Office and local dealership.
Liberal Party had a word for this !
Lovely car  but terrible problem due to DPF regen system.
As I have commented on another site, get your dealership to sign' in 'blood  that it will drive the 12500miles before needing  a 'service'.

It is not really the total mileage you do but whether it gets hot before you switch it off. If it gets hot, it burns the excess fuel from the oil. You do more than 12.5K miles per year but still it does not work out.

There is a good chance that the first owner sold it for the same reason that makes you unhappy. But the first owner was doing 2K miles per year. So maybe the first owner had no problems at all and was doing an oil change once per year and everything was good.

Please explain what you mean.

There are older posts of people who mentioned that their oil level was going up when driving in town and down when driving without stop start traffic.

Also, even small petrol city cars, have their oil level going up when driving cold all the time. When they drive longer distances without stopping and starting all the time and the engine gets hot, it burns the excess humidity building up in the oil and showing as high oil level.

There is no way to prevent burning oil. As there is excess fuel in the engine, some of it mixes with the oil and if driven to specific conditions, it will start burning.

All the dealers have to say is driving outside the manufacturer specification. That is why the handbook has reduced service intervals for adverse conditions. However, most of the people stick to the longest possible interval.
