How much fuel does a 1.5t car consume when running the AC overnight?

1.5t car running the AC overnight, depending on the vehicle's displacement, generally consumes over 10 liters of fuel. Additional information is as follows: 1. Engine: The engine's operation mainly maintains the functioning of the air conditioning compressor, water pump, oil pump, flywheel, etc. If the clutch is engaged (clutch pedal not pressed), the engine also needs to drive components like the transmission input shaft gears. 2. Engine idling: Engine idling also consumes a significant amount of fuel. If idling only drives the air conditioning compressor, more energy is wasted, and the engine remains at high temperatures for extended periods, potentially leading to carbon dioxide buildup.
Hey, as someone who frequently tinkers with cars, I know a thing or two about running the AC overnight in a 1.5T vehicle. Generally speaking, when idling with the AC on, the engine RPM increases to power the compressor, consuming approximately 0.8 to 1.5 liters of fuel per hour. Assuming you run it for about 8 hours overnight, total fuel consumption could range from 6.4 to 12 liters. The exact figure depends on the car's age and condition: newer models like the Honda Civic might be more fuel-efficient, while older ones like the Geely Boyue could guzzle more. Temperature settings also play a crucial role—running high cooling in summer consumes significantly more fuel than using the heater in winter. The AC compressor is a real fuel hog; I've tested it on my own 1.5T car, and during hot weather, leaving it on overnight can drain nearly a small fuel canister's worth, around 10 liters. Not only is this wasteful, but it can also lead to carbon buildup and engine damage. I’d advise against doing this often. If you really want to save fuel, turn off the AC before shutting down the engine when parked in a safe spot. Safety first—never let exhaust fumes accumulate in an enclosed space.
