It was the little engine that couldn't — because it was thirsty for fuel.

Motorists in southern Sweden took advantage of criminal tinkering at several gas pumps to load up on free fuel last weekend, officials say.

The third time was an alarm for a Cadillac driver apparently loading up on free gas while posing as a stranded motorist. A police officer became suspicious the third time he saw the same man stopped on the side of a road next to his Cadillac with the hood up, said Charles Gonzalez, the area's neighborhood police officer.

Two prayer services will be held at St. Louis gas stations to thank God for lower fuel prices and to ask that they continue to drop. Darrell Alexander, Midwest co-chair of the Pray at the Pump movement, says prayer gatherings will be held Monday afternoon and evening at a Mobil station west of downtown St. Louis.

The office of Britain's Prince Charles says the royal has converted his 1970 Aston Martin car to run on surplus wine-based biofuel.
