1 Answer

Answer :

answer:A cars engine naturally degrades of time and use. Using oil as a way of lubricating the massive friction produced by the constant motion of the pistons. Naturally an older engine will have more of a degrade than a newer one. Also, you just really need to let the oil heat up rather than the engine temperature. The oil is much thicker and actually harm engine components when it’s cold. Also, oil pressure plays a factor in this too. If the oil is too thick (due to it being cold) it won’t be able to flow freely throughout the engine as intended and some parts of the engine could still be dry because of that fact. Realistically you should always let it run for at least a few minutes before operation, but that could just be me.
