Tank it's 50litres, if you divide 50/4 , each quarter gives around 12.5 liter.
with this average I would be doing around 250km for the whole tank fill up. But I think it might have to do with the idling at 800rpm. It's way high

Idling at 800rpm wouldn't cause a dramatic difference in gas consumption (and besides, you shouldn't be idling through a significant portion of the tank anyways - that'll wreck your gas mileage no matter what speed your idle is). As for your calculations, gas gauges are almost never accurate enough to do that sort of calculation - the only reliable way to get fuel mileage is to look at how much gas you put in when you fill it up, and then divide the actual distance traveled since the last fuelup from the odometer by how much gas you put in.
Secondly, how are you driving? Is it primarily city driving? Highway? What speed? What RPM range are you keeping the car in? How long is your average trip (from starting the car to turning it off again)? All of these factors can dramatically affect gas mileage.
