The range of opinions will be exactly the same as every other oil thread you've read.
There will be no definitive answer and you'll have to decide for yourself.

5w30 or 5w40 it doesn’t really matter, personally I’d go 5w40. I wouldn’t be using 10w however

im going to put 5w40 in.

0w/30 A5/B5

Same for me 0w/30 A5/B5 in my D5.

0W/30 A5/B5 is not viscous enough when the engine is up to operating temperature. 5W/40 A3/B4 is the better grade of oil for these engines.

What does this site say?

The recommendations of Volvo are based moreso on emissions and economy rather than engine protection. Many aftermarket suppliers of oil simply follow OEM recommendations, which can lead to oil being recommended for the wrong reasons. At 180k, I'd say with absolute certainty that the wear on the engine is such that it would be madness to use a thin oil such as 0W/30. The ACEA spec is great for fuel economy and emissions, but in terms of actual engine protection and preservation it's just not up to the job.

Of course it is , It is what Volvo recommends as the premium oil for D5 ! They specifically said do not use a 40 grade oil in their oil charts 13 years ago ...
