Would hate to think wha3 the Dodge 2500 gets for MPG when properly using smog equipment - as its defeat software seems to render a mpg estimate roughly the same as Ford & GM. that DIDN'T (OSTENSIBLY) equip with said software.
Tough to say. American (non-commercial) diesel drivers have managed to earn a reputation for being willing to screw over anyone and everyone to get a little more of this for a little less of that.
I suppose. Of course there's a segment of gassers as well - that are equally opposed to all things related to a clean burn - as it presumes to decrease power.
