In a 2015 Nissan Altima with a 2.5L 4-cylinder QR25DE engine, you should use either 0W-20 or 5W-30 motor oil. Although 5W-30 is acceptable, the recommended choice is 0W-20. This vehicle requires 4.9 US quarts of oil when including the filter, which is slightly less than 1.25 gallons. To ensure a complete fill-up, it's advisable to buy a jug of that size. The oil drain plug requires a 13mm socket for removal, and you should set your torque wrench to 22 ft-lbs.
