What does odo on a car mean?

[DiElliott]

Odo on a car refers to the total mileage the vehicle has traveled, and this data cannot be reset. Car owners rely on this data to remind them of the vehicle's maintenance schedule. In contrast, trip refers to the short-distance journey of the car, also known as the subtotal journey. Its main function is to calculate the mileage of the car before each trip, and it can be reset. The odometer in modern cars serves a dual purpose: it not only tells the owner how many kilometers have been traveled during the current trip but also records the total distance traveled since the car left the factory. This provides a reliable record for determining whether the vehicle needs a major overhaul or if the engine's proportional relationship suggests it should be scrapped.
