Prior to that, diesel had been consistently cheaper than gas to run.
But since then, diesel prices have absolutely skyrocketed compared to gasoline prices. Even though I am only getting about 8-12 MPG out of my 6.6 gas, it is still cheaper to run than the duramax would be.
For cars, diesel still makes some sense, being that you can get 50+ mpg by using it.
