Although I beleive this has been superceeded by the new GM Dexos II specification, I'm wondering if anybody has any specific information on its properties.
From what I've been able to gather I reckon it must have a HTHS of at least 3.5 cP, as I haven't seen an oil meeting this spec without an ACEA A3/B3/B4 specification. But does anybody know if there's a certain base oil that is required? Or a minimum TBN? Minimum sulfur content? Thanks!
