Sooo, the datasheet is from later 2015. Did they revise their formula and not tell GM or submit the new formula for approval, so therefore it got left in the Performance Supplement by accident?
Dexos 2 is not a new standard, it's been in EU for years. We're just not used to it in the USA because there are so few applicable Diesel engines here.
