Re: Oil Pressure Volvo D3 I - C
We had a similar symptom, but did not have the thin oil that you are experiencing. So, I do not believe your issue would be the same. As others have suggested, a potential source of diesel in the oil would explain the low viscosity.
In our case, it was the oil pressure switch (sensor). I would recommend removing the oil pressure switch and installing a temporary pressure guage, so you can eliminate the possibility of a bad switch. I believe at idle, you should maintain 1 bar of oil pressure.

since yesterday I have an oil pressure problem on my AMEL 54#96.
When I go from normal speed to idle, the oil alarm starts.
Of course, this doesn´t happen in the port but between the islands in Croatia.
My German Volvo expert suspects that the oil is too thin.
Diesel has probably gotten into the oil.
That´s why I changed the oil. More than 7 liters of very thin oil came out.
Then the engine ran again without an oil pressure alarm.
But today, when I switched back to idle, the alarm went on again.
I appreciate any advice or experiences.
Thanks a lot,
