Arrow 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.

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.

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.

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?)

Smile 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! 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.
