Best oil weight
5W-20 is recommended, 5W-30 is OK to use. Neither will make the engine last any longer. Changing it at regular intervals will.
Use the oil viscosity based on your car and the weather temperature. Thicker in winter, thinner in summer is best. Which means you'll change the oil twice a year.
