When you buy a used car, you must make an appointment to see the car for sale and, in particular, require that it not start or heat up until you get there. When you arrive, you can open the hood and feel the temperature of the engine by placing your hand on the block or next to the block, which is the main component of most of the engine.

The oil that is in the dipstick when it is removed should be amber and mostly transparent. The darker and sandier the oil, the worse the car stays. The oil level is also important, as it will tell you if the car is flowing or fuel is burning, and it will also inform you a bit about the history of car maintenance.
