How often should I change the oil in my 1989 Mitsubishi SIGMA?
For modern models running full synthetic oil, oil change intervals are typically every 7,500 to 10,000 miles. However, for older Mitsubishi SIGMA 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 (3.0L 6-cylinder), you should change your oil at least once a year even if you don’t reach the mileage limit.
