Actually, from what I've read, it can burn either kerosene,
petrol, or diesel. Quoting from wikipedia: http://en.wikipedia.org/wiki/M1_Abrams
The tank can be fueled with diesel fuel, kerosene, any grade of
MOGAS (motor gasoline), or JP-4 or JP-8 jet fuel; the U.S. Army
uses JP-8 jet fuel in order to simplify logistics.
That said, the biggest issue that the Abrams has is definitely
its gas turbine. It high-temperature exhaust makes it difficult for
infantry to run behind it for protection in urban areas.
It also has a high rate of fuel consumption. Heck, you need 40
liters of fuel just to start up the turbine.
