results from garage
 

So, i just finished up in the garage. Car was jacked up after running shortly to get oil lukewarm. Oil was drained through a sieve into a clean container. After this the oil filter housing was taken off, poured into another container, and filter changed. Old filter was then cut open and spread out.

Result, no metal fragments what so ever. None, Nada. Not even a single piece of glitter.
The oil filter and housing also seemed mostly clean, except for a few really small pieces of brown plastic, as expected. The variocam pads are worn and breaking down, I know this already and the job is planned.:rolleyes:

As for the look of the oil, it now has a lighter more milky look after i added Liqui Moly Ceratec, as this is offwhite. Looking closely at the oil now, it still looks a bit like before, but I suspect that there is moisture in the oil, as i could se a couple of "bubles" in the oil. Also, there was droplets on the oil filling cap. But there is no "mayo" of any kind. Analysis will tell. :rolleyes:

Poured the oil back in the engine. Analysis will decide what to do later.

Also, test container for oil sample came in the mail today. I will drive the samle and documentation to the lab tomorrow. I chose the fast 24h variant that costs double (around 100usd), which means I will have my report monday, maybe even tomorrow evening.

Washed the car and put her i storage for now.

Thanks for good tip on the blotter test. I will try that, even thou i will get results from test pretty soon.

Sieve i ran the oil through. Completely clean.

blotter test
 

I did the blotter test on coffepaper just now. :)


After about 40 seconds the oil is absorbed outwards. There is a bulb of oil in center and a "wet" circle outside. Seems pretty normal, right?:rolleyes:

After 10 minutes i checked back. All oil is absorbed already. I looked at the spot with a magnifying glass, and could not see any debris. So nothing worrying about this, right? Now i just wait for the oil report.

It would, when there is enough of it. But if you have slight condensation and it hasn't mixed into all the oil you can get these "layers". I've had a couple of outboard engines with both slight and massive water intrusion in the underwater housing/gear oil. with a lot of water its milkshake look if the engine has been run a lot and properly mixed. If its just slight, and the engine hasnt been run a lot, you can see seperation layers. Some clear oil, some more milky.

I did find moisture/droplets in the oil filler cap.

But the oil report will tell. :) i'm starting to be optimistic.

First of all, everything looks good imho, but I would use normal paper and not a coffee filter, the coarse structure may make it difficult to recognise the boundaries that form...

Looks good to me also. Suggest you drive the car since a hot engine will "boil off" any SLIGHT amount of condensation in the oil if given enough of a chance.

Obviously, that works with SLIGHT amounts of condensation. But if not "slight" I would investigate deeper. (any loss of coolant level?)

report
 

Delivered sample today at 11, they said i would get result by monday. But got the result before evening! GOOD NEWS! No abnormal wear metal levels! :D Reading results there is condensation in oil, but not very much. It does contain a bit too much gasoline thou. I cleaned the catch container with gas before i drained oil into it, but i dont know if that would make the oil thin.

Anyways I do not have a problem! But even thou test looks good, it does not explain why the oil looked weird. I will change the oil, based on looks. As my dad suggested after working on differrnt engines for a lifetime. I will keep an eye out on the value of aluminum in the oil thou, as it might be high for such a short runtime.

I want to thank everyone who has contributed with their time and effort to help me with tips and suggestions in this thread. Thank you.

The comment/report said the following (google translate from norwegian):

Comment
Missing information on specific oil in use, as there are several Mobil 1 3000 5W-40 variants.
The analysis (evaluated against SAE 5W-30 generally) indicates some gasoline present (low viscosity and low flash point). Requires that the sample be taken from operating hot oil (some gasoline will always be present, but this normally evaporates during operation).
The wear readings appear normal, no indication of abnormal wear detected. Water content
normal, no indication of possible coolant. The oil is somewhat thin, but this need not be
abnormal.

What kind of oil is it that contains so much boron and molybdenum? Very unusual. Additive? Otherwise the viscosities should be more or less the same as the fresh oil, or the remaining oil (which is 20% of the total filling quantity) was completely empty!?

It's mentioned in the first post and some of my replies. The reason i drained off some oil to begin with, was to add Liqui Moly Ceratec. The boron oxide and moly is part of the antifriction package in ceratec, that supposedly reduces chance of bore scoring, and reduces metal on metal friction.

The oil itself is a porsche A40 rated oil: mobil1 3000 x1, 5w-40.

The viscositie is somewhat compromised by fuel/gas in the oil according to the report.

Looking at the color of that stuff and given that you used two bottles of it, this could explain the look of the oil!
Edit: I read your first post, you said "you made room for Ceratec", I was not aware that it was already in the oil.

Sorry if this ended up unclear. To clear up:
In first post, there is NO ceratec in the oil. The picture of the oil that people reacted on was just pure used (10h) oil. The ceratec was then added, and car driven to/from work.

Then, the car was jacked up for a second time, and ALL oil was drained out through a sieve and filter cut open. This is when i took the sample (then with ceratec in it). Since there was no metal, oil was poured back in and driven some more. I have now decided to change oil regardless. As my dad said, i really just have the word of last owner that the oil has been changed annually. Car is new to me, this is my first oil change on this one. Before that, when car was in the US, interval was whatever porsche recommended at the time. So there might be all kinds of sludge/residue in there.
