AC Delco Dexos 1 Synthetic Blend 5W30 vs Motorcraft Synthetic Blend 5W20
Anyone else notice a bit of similarity between the new AC/Delco 5W30 and MC 5W20? I have to wonder just how similar the MC 5W30 Blend specified in the new Ecoboost is to Dexos 1. Anyone now if they are both supplied by Conoco-Phillips?
