When I changed the chassis wiring harness in the engine bay of my truck, I used a Dremel tool with a wire wheel to clean all of the chassis ground posts, all of the grounding nut surfaces, and all of the ground loop connectors on the harness. After that, I coated all of the exposed metal with dielectric goop, then put them back together.

The net result was (other than to get rid of a really annoying intermittent condition whereby my transmission would just decide to go into limp-in mode for 5 seconds while at speed - with no codes, of course) that my truck now tends to go into DFCO a lot more easily than before. There are sections of my commute where the truck will actually do DFCO regularly, whereas before it never did.

I'm tending to lean toward "DFCO = fuel savings," myself.
