Hey, you guys might be interested in this. In fact, I should make this a brand new post.
So I emailed Castrol and Valvoline asking if they had any oils that would meet the qualifications for this motor. I mean it says Castrol oil recommended right on the oil cap. These are the two responses I received.
Hello, Volvo recommends Castrol. This particular vehicle requires an oil that is ACEA A5/B5 rating. Which of your products do I use? I am in Idaho.
Thank you,
Thank you for contacting Castrol North America.
Castrol EDGE 5w30, Castrol EDGE Extended Performance 5w30, and Castrol EDGE Professional 5w30 oils all transitioned to ACEA A5/B5 on April 1, 2017.
Please note that the specification for ACEA A5/B5 changed in 2015 and as a result, Castrol EDGE 5w30, Castrol EDGE Extended Performance 5w30 and Castrol EDGE Professional 5w30 oils did not meet the new ACEA A5/B5 specification for a little while however since the change at that time was a bio-diesel oxidation test that our oils did not meet, Volvo still accepted/accepts the use of the above mentioned Castrol oils in their vehicles in North America.
Volvo dealerships primarily sell Castrol EDGE Professional 5w30.

And from Valvoline:
Stephen, thank you for contacting Valvoline Product Support with your question.
For an API rating ACEA A5/B5: the only product we have that cover that specification would be Valvoline Full Synthetic with MaxLife Technology. The only Viscosity we would have for you application would be 5w30. If you have any further questions, please feel free to contact us via phone at 800 TEAM VAL or by email at
[email protected] for assistance.
Thank you and have a great day.
