We have a new to us 2016 Volvo XC90 T6 Inscription with suspect service history the last couple years. On top of that the dealership chain I bought it from is notorious for using all sorts of "profit" additives and using Pennzoil motor oil in all of their cars regardless of what the manufacturer recommends. I'm doing all the maintenance on the car and want to get it on a quality high milage oil, Volvo requires an ACEA A5/B5 5w-30 oil. Is the M1 5w-30 HM currently the only high milage oil meeting this requirement? Thank you for the assistance. My searching both here and google turned up little help.
