Cadillac 1 - the Beast
2009-2013: It's a diesel
3/20/13: Actually it's gas-engined.
Am I the only one tired of being lied to? In this case, it seems like the plan is to discredit whatever people are saying, regardless of whether it's the truth.
Secret Service spokesliar: Oh, no, it wasn't the wrong fuel. No, it was some enormous mystery. We'll figure it out right away and get back to you with a full report.

"The appropriate gas was put in the car," Ed Donovan, spokesman for the Secret Service, told CNN. Citing an official in the region, CNN reported, as did other media outlets, that the vehicle had been filled with gasoline instead of diesel fuel. At the time, the Secret Service did not waive reporters off the idea that the car had the wrong fuel.
Donovan said the vehicle actually doesn't have a diesel engine and runs on unleaded gasoline. The Secret Service is generally tight-lipped about details of the president's limousine, otherwise known as "The Beast."
Because the vehicle was built on a Chevrolet Kodiak chassis, whose engine runs on diesel fuel, it was believed that the limo also ran on diesel.
