Re: MDS Functionality
All V8s have MDS. You can chose to have ECO displayed in the EVIC, which typically means MDS is active.
If you are cruising at a steady speed, you can usually feel/hear the cylinders drop out as it has a king of rumble to it. As soon as you apply some throttle it will pop out of MDS.
If someone put thicker oil in the crankcase, that could keep MDS from operating.
