My mother's car is a 2011 Chevy Malibu with the 2.4 litre EcoTec engine. This engine doesn't have direct injection or VVT, as the new 2.5's do. This engine is basically A larger version of the 2.2 EcoTec that have been beating around on conventional for over a decade, best I can tell from what I've read about it. My question is, would Motorcraft Syn Blend work just fine? It calls for Dexos 1, but so do the 2011-13 Chevy trucks with the 4.3 V6 and the 4.8/5.3/6.0 LS engines, and those aren't direct injected or equipped with VVT either. My thinking is that GM wanted their customers to become used to the requirement, so they used it across the board. Since the Motorcraft is a syn blend, technically it should be fine for a dexos requirement, but GM isn't going to approve a Ford branded oil. Advice much appreciated in advance.
