A guy local here has a 2 wheel drive first gen dodge set up similar with a gear vendors 2 speed as extra over drive. He can click off 30 mpg on the highway with it. There's potential in the new trucks but it won't meet epa stuff so we the end user get screwed. I still can't figure out how a truck using 1/3 more fuel can burn cleaner when you're dumping extra fuel in to burn off the particulate filter. It contaminates the oil in mine so bad I won't go the recommended 7.5k mile oil changes. After 5500-6k the oil smells like fuel and there's almost an extra quart. It's about time to start complaining since I'm 2/3 through the warranty now. It didn't seem to do it at first that I remember.
Haa, no kidding, a two speed aye? I remember having a three speed in a cutlass hot rod. It was quite a trip getting used to that coming from a 5 speed.
So what's with that ideology? More fuel to pass emissions? That is just a$$ backwards. Something needs to give, i guarantee the EPA is soon going to become something we see everyday on the streets enforcing there idiotic laws passed by pencil pushers. Pencil pushers who couldn't even tell you which is which if presented with a unlabeled gallon of diesel & gas, yet continuously pass there feel good legislation that severely impacts all of us. Like i already said, something needs to give.. Oh boy I'm starting to rant.. Sorry..
Oh yeah, btw, I'd definatley raise hell over that before your warranty runs out. You know who's going to be holding the bag when that problem breaks something big, but I'm sure you already know that.
