How often should I change the oil in my 1990 Ford Mustang?
Most 1990 Ford Mustang owners follow a 5,000–7,500 mile interval with conventional oil, or up to 10,000 miles with full synthetic. Always check the oil life monitor if equipped, and consult your owner's manual — Ford recommends intervals based on driving conditions, not just mileage.
Can I use synthetic oil in my 1990 Ford Mustang?
Yes. 10W-30 is widely available as a full synthetic, and synthetic is safe (often recommended) for the 1990 Ford Mustang. What matters most is matching the factory viscosity and specification, then changing the oil and filter on schedule.
