Oil pressure

Oil pressure is the amount of pressure on the oil inside an engine. That pressure is created when the oil is pumped through small channels and holes inside the engine. That pressure helps keep the engine running, because it helps the oil reach all the parts that need it. Without oil pressure, parts inside the engine would get too hot, and the engine would break down. So having a good amount of oil pressure is important for keeping an engine running.
