Ever hear of Pricelock? It's a service for fleet operators to purchase gas in bulk at a set price to buffer the company budget from rising fuel fluctuations. Chrysler thinks that new car buyers should be able to participate as well, through the company's new "Let's Refuel America Gas Card."

Chrysler announced a three-year $2.99 price guarantee on fuel costs to anyone who buys a new Chrysler, Dodge or Jeep vehicle between tomorrow and June 2. Certain vehicles, like SRT models, Vipers, Crossfires and Sprinters, are excluded. Other limiting factors are that you can only buy fuel (regular gas, diesel or E85) that works in your new car and there's an annual limit based on driving 12,000 miles. So, there won't be a lot of hooking up your friends through this deal. The deal works at any gas station because the savings are taken care through a credit card on file with Chrysler; the fuel supplier charges the full price, and Chrysler pays the difference.

Let's calculate this out. Pretend you're about to buy a PT Cruiser convertible. The EPA says it gets 21 mpg (combined). So, 12,000 miles at 21 mpg is 571 gallons. At today's average gas price of $3.61 a gallon, you'll be saving 62 cents a gallon. During the first year, that's $354. Over three years - should gas prices stay the same (ha!) - you're talking $1,000, easy. Is that enough to make you want to buy a Chrysler? In any case, should prices ever dip below $2.99, nothing will stop you from paying for your gas without using the Chrysler-bound card. Get more details after the jump.
