Oil choice and spec question. At an independent Volvo service shop today I received 0W20 Service Pro Full Synthetic Oil. I looked up the Service Pro Euro Synth and see they make a ACEA A5/B5 spec (or the Volvo RBSO-2AE spec) but not for 0W20. I don’t know a ton about how much it matters to meet the Volvo spec, or to absolutely use the Castrol Edge Professional recommended. When the car used to go to dealer it got Edge, but typically at the 5W30 weight as I don’t think Edge pro is available in 0W20 in the US.
What matters more - the 0W20 weight, the exact oil spec/certification (which limits the choices a lot for Volvo) or the brand?
