Hello everyone, a question in the round: On my former XC70 2 (B/P24) 2.4 D (Bj 2010) according to the operating instructions, since 2.4D engine, an A5/B5 oil in 0W-30 is given, which he also got during my ownership times. Now the free with the successor owner 5W-30 has filled, because there would be O-ton “a 0W-30 from Castrol no longer with the release for it.” Then a “Castrol Magnatec A5/B5 5W-30” was taken. Where can I find that this oil or generally which oil except the 0W-30 was released for the vehicle (there is nothing else in the instructions but 0W-30)? Question 2: Of what large oil company is the 0W-30 produced, what Volvo has always filled up with me, and is this oil actually no longer present today. I have the impression that the freeman wanted to fool the afterowner somewhat.
