Yep. Diesel in my area is in the 1.90 range. Still advantage diesel when you do the math.
Not always. You have to factor in the additional upfront cost, and the higher cost of maintenance as well. When fuel prices are close between gas and diesel, it's a close comparison. When gas is a lot cheaper than diesel, like it was just a year ago, the math doesn't work in favor of the diesel at all.
With the Colorado, I believe the diesel option is about $3700 over the V-6.
The V-6 will already scare 30mph to death on the highway. The diesel isn't going to beat that by much, so just going on fuel mileage alone, it'll take you probably over 30k miles for those prices to break even...and that's without factoring the significantly higher maintenance costs.
Still....it'd be a pulling beast in that truck, no doubt.
