Fuel consumption - Toyota Mark II, 2.0 liter, 1993

Pretty topical question for markovodov :) So I became interested and decided to measure!
When buying, 2.5 years ago, in the summer I measured fuel consumption. It turned out 12.5 liters per 100 km. Which is pretty good for a brand.
In winter, the consumption jumped like 2 times, but I never measured it.
This summer I measured the consumption on the highway with a stop in major cities. After driving a couple of thousand kilometers, the consumption was 8.9 liters per 100 km. But if you take into account the full load of the car and the included air conditioner, traffic jams in cities and off-road driving, then this is still normal.
But the other day I measured the flow rate at a street temperature of 0-5 degrees. The car is parked outside, so it warms up 10 minutes before leaving.
I drove almost 350 km at 45 liters, total consumption is less than 13 liters. I wonder what the consumption will be at -20 and at -30))

Generally satisfied with the result. But, I think, the owners of modern cars and small cars break into a smile, seeing my gigantic numbers)))
