A dipstick is a tool used to measure the level of oil in a vehicle's engine. It is a long, thin metal rod that is inserted into a tube in the engine. The dipstick has markings to indicate the oil level. To use it, the dipstick is pulled out, wiped clean, put back in the tube, and taken out again to see where the oil marks. Checking the oil level regularly with a dipstick is important to ensure the engine has enough oil to run properly and avoid damage.
