Seems obvious the US consumer requires a gentle nudge toward extended drains, and this might be Mobil's way of drawing attention to it's products. Does the average guy on the street or even hardcore M1 Junkie know what MB 229.3 or VW 503.01 really is anyway? Now it is spelled-out for them, blah- 15,000 miles. There should also be a reminder on the label to top-off during the extended drains...with Mobil 1 XD of course. used oil analysis should prove interesting, verses GC.
Yes, Mobil gives the best bang- DCO, Delvac 1300S, 0w-40, T&S. I consider myself a Castrol guy from their position as a racing sponsor and personal endorsments, but other than GC I use Mobil products.
PS, a lil visc range info would be nice. Is extended drain to be the exclusive domain of 0w oils???
