To get the best performance from your 2005 Nissan Altima with its 2.5 L engine, it's best to use a fully synthetic SAE 5W-30 motor oil. This type of oil provides numerous performance benefits and the Altima can hold up to 4.4 quarts of it. If fully synthetic oil is not available, a semi-synthetic 10W-30 oil can also work well. Many users have found success with this viscosity. It's recommended to change your oil every 3500 to 5000 miles for optimal performance. If you can't find the original Nissan motor oil, reputable brands like Motorcraft and Castrol are good alternatives.
