Hello, I’ve already read a lot in the forum about oils or the right oils for Saab engines. Now I have a question that might answer the nice, clever leude here. I’ve read that Saab oils is Mobil1 oil or is equivalent to Mobil1 oil. Can you assume that Saab oil can also be equated with GM oil, or else asked, is Saab and GM oil the same soup? I drive a 2.2 tid and would Mobil1 5w30 or 5w 40, if this is equivalent to GM oil, I would take this. Reason : up to half cheaper / see http://ssl.delti.com/…/DA.pl?… Thanks already for the answers. Greetings Smöre
