The USEPA is very anti-diesel, and the regs they issued (this was during Bush, before Baraq) are extremely stringent.

They increased the purchase price, reduced fuel economy and performance both, and required the conversion to ultra low sulfur fuel which is now considerably more expensive than gasoline.

I'm reading in trade pubs that smaller sized construction equipment is actually going from diesel to gas because of this.

Gas as in Gasoline or Gaseous aka, Propane, LNG, CNG?

With the Fracking Revolution the latter ones are coming on strong in their own right, as I am sure you have read.
