Maybe I've missed it, but do you guys know that there will be 2 different types of Dexos?
Dexos1 for America with emphasis on fuel economy and Dexos2 for Europe with higher limits on SAP levels. US will also get Dexos2, however Europe does not need the Dexos1 as it looks for now.
Dexos1 needs to fulfill the ILSAC norms and Dexos2 needs to fulfill ACEA C3-07. Basically Dexos2 is more or less designed for Diesel engines AND spark ignited engines, where Dexos1 is only for spark ignited engines.
“dexos1™ replaces GM-LL-A-025, GM6094M and GM4718M.”
“dexos2™ replaces GM-LL-B-025 and GM-LL-A-025.”
