You seen how much fluid the engine/transmission hold?!

100 litres fuel
40 litres water (eng coolant)
15 litres water (charge coolers)
20 litres engine oil
22 litres g/box oil
15 litres hydraulic oil

I'm guessing oil weighs a bit more than water but if that 207 litres were water then thats 207kg so its gonna be more than that!! no wonder it weighs 2 fookin ton!
