I don't know how things are there, Gasoline is expensive here in the US. I know that a 1KW Honda generator is far more fuel efficient than running say, a Honda Civic for field day. The Civic is rated at 117 KW, which, to say the least, is overkill. An 1800 watt Honda generator will run for 16 hours, at 900 watts, on less than a gallon of gasoline. At 400 watts, it will run for 17 hours on the same amount of fuel. That means it will run for all of field day, and then some, for less than 6 dollars worth of fuel. I can tell you my pickup truck would cost a small fortune to run that long.
