For modern models running full synthetic oil, oil change intervals are typically every 7,500 to 10,000 miles. However, for older Nissan/Datsun 810 generations (1985-2010) or those using conventional/synthetic-blend fluid, changing the oil and filter every 3,000 to 5,000 miles is highly recommended to prevent sludge buildup. Regardless of engine (2.4L 6-cylinder and 2.8L 6-cylinder), you should change your oil at least once a year even if you don’t reach the mileage limit.
