What does mpg mean on a car?

[Archer]

MPG on a car stands for miles per gallon, which indicates how many miles a vehicle can travel on one gallon of fuel. Here is some knowledge about car mileage: Methods to identify car mileage: The mileage can be judged by the degree of wear. The wear on the steering wheel. Seat wear: After prolonged sitting pressure, elasticity decreases, aging becomes obvious, and the leather may become shiny and hard. Plastic knobs and adjustment levers in the car. Brake pad wear: Generally, the lifespan of brake discs is over 100,000 kilometers. Tire wear is the most intuitive indicator of the distance a car has traveled. The aging degree of the interior. Methods to test the car odometer sensor circuit: Test the voltage waveform: Rotate the transmission's output shaft and use an automotive oscilloscope to detect the signal voltage waveform between the two leads of the speed sensor. It should show an AC waveform, with the amplitude and frequency increasing as the output shaft speed increases, indicating good sensor performance. Check the resistance of the leads: Remove the speed sensor connector and use a multimeter to measure the resistance between the two leads of the sensor to see if it meets the standard requirements.
