The amount of oil a 1967 Ford Mustang needs depends entirely on the engine it has. There were several different engines offered that year. You
must check your owner's manual (if you have one) or the sticker under the hood (if still present) to find the correct oil capacity.
Generally, six-cylinder Mustangs required less oil than the V8s. You might find capacities ranging from approximately 4 to 6 quarts. Do not attempt to add oil without knowing the correct amount for your specific engine. Overfilling can be just as damaging as underfilling.
