No, 1967 Ford Mustangs did not use standard power steering fluid as we know it today. They used a
specific type of power steering fluid that was generally mineral-based. While some modern power steering fluids might *seem* compatible, using the wrong fluid can damage the seals and components in a classic car's power steering system.
To be safe, you should always use a power steering fluid that is specifically formulated for classic cars, or that matches the specifications listed in your owner's manual or a reputable restoration guide for a 1967 Mustang. Attempting to use a modern, synthetic fluid could lead to leaks or internal damage.
