How often should I change the oil in my 1984 Chevrolet Monte Carlo?

For modern models running full synthetic oil, oil change intervals are typically every 7,500 to 10,000 miles. However, for older Chevrolet Monte Carlo 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 (3.8L 6-cylinder, 5.7L 8-cylinder and 5.0L 8-cylinder), you should change your oil at least once a year even if you don’t reach the mileage limit.
