What is best for engine work: oil discharge or suction?

One of the most important things to keep in mind is changing the engine oil at its specified time, so that the car engine is maintained from breakdowns and damage. When the engine oil is changed, the driver finds that he has two choices, either oil suction or discharge.

Changing oil through suction or drainage is different for many motorists, some of whom say that oil suction through the pipe is harmful, because the pipe will not reach all corners and bottom of the engine, leaving little oil that is dirty with impurities.

Oil discharge from the bottom of the engine will eliminate all oil deposits and metal impurities, but some suction proponents say that over time discharge may cause a little oil to be smuggled out of the oil outlet when discharged, and that the bolts can be lost during drainage.

Finally, the oil change through the suction and discharge methods is correct, and the important thing here is not to neglect the change of engine oil to maintain the efficiency of the engine and its internal parts.
