If you do the math.... At your average 14.5 mpg, and 12k miles per year at $3.60/gal. That is $2979.00 per year.
If you assume the diesel will average 18.5 mpg, which I think is conservative, and at 12k miles per year and $4.00/gal, you would pay $2594.00.
The diesel would have to average 16.1 mpg, for the costs to be equal.
