The fuel consumption is much higher than usual today. What happened?

Mountain climbing has something to do with it. The cold weather only affects the first stage, and the water temperature will be normal when it comes up. Strong winds have little effect on fuel consumption. If the manual shift timing is wrong, it will affect fuel consumption. To sum up, combined with the distance from Beijing to Baoding, it should not lead to the increase of oil. Comprehensive analysis should be other problems, such as wrong refueling, dirty throttle, clogged nozzle, engine carbon deposition and so on.
