For a healthy car, lubrication in the form of engine oil is essential. Your engine needs this oil in order to work properly and so it is vital that you keep an eye on your fluid levels, and continue to check these regularly. Engine oil will start to degrade over time and does not self-clean so it will keep getting dirtier and less efficient as time goes on, which is why it will always eventually need replacing. Should your engine require a top up, it is important that you choose the right oil for your specific vehicle.
