Can You Add Cold Oil to a Hot Engine?

Many people are familiar with the old adage that you should never add cold oil to a hot engine, as doing so can cause damage. But what does this really mean and why is it bad for your machine?

The best approach is always to allow your engine to cool down before you add any additional oil and use only the recommended amount for your vehicle type.
