0w20 Worked for Me
Adding a data point here.
I've been having the clicking issue described in this thread for quite a while. I have a 2015.5 V60 2.0 drive-e. Bought the car with about 10K miles. Noticed clicking soon after purchase. Just found it annoying. Now 50K and the issue has been a bit more noticeable. Still not a super common occurrence, but I could pretty much replicate it on demand. Dealer was zero help under warranty. Read this thread prior to my last service and specified that 0w20 be used. My mechanic put Motul 8100 0w20 in. It is not the Volvo specific formulation, but is probably pretty close. Had a long talk with the folks at the garage and they assured me all would be well and it was worth a try. Well, on the way to the garage I replicated the pinging once or twice just to make sure. Got the symptom as usual. Post oil change I cannot generate the LSPI issue. I have tried every scenario that I've ever had the issue. No problems. So the oil switch did the trick for me.
