I do about 15k a year, I usually get 250 miles winter/280 miles summer per 75 liter tank.
Two adults,one child, babysitter, school, work, hardware store etc. City is horrible planned and it takes at least 15 minutes to get anywhere.Very rarely does the coolant level never reach operating except for the very cold days. As for oil temp, I have no gauge. Pretty standard stuff except for a 420 mile trip(total back & forth) once every three or four weeks to a neighboring city.
P.S Although I am with the rest of the world with my country's system of measurement, I am using miles in this instance.
