The triple whammy (Tier II/ULSD/CA ban) has made a mockery of our efforts to get better MPG by robbing us of a powerful tool for better MPG. The triple whammy has made diesels too expensive, too inefficient, and forces their fuel prices so high as to not be worth the bother.

We all know diesels get much better MPG. We could duct tape our grilles and make belly pans until Hades freezes over and it would not be as effective as substituting a (non-TierII compliant) diesel to the vehicle. One need look no further than the old saY 2000 VW Jetta. The gas version got 27 MPG (EPA) and the diesel was over 40.
