This is incorrect. The only thing Ford changed was the label and the way they market Motorcraft 5w20. The formula (developed by Conoco) hasn't changed at all: it's a Group III and Group II base oil blend. Taking a cue from Castrol, Ford has decided to call it a "synthetic blend" because of the Group III. Conoco's Hydroclear 5w20 is the exact same oil, but Conoco doesn't market it as a syn blend.quote:
