The recommended oil for a 2000 Ford Mustang depends on the engine it has. There were several engine options available that year. You
must check your owner's manual for the precise recommendation. The manual will specify the correct viscosity (like 5W-20, 5W-30, 10W-30, etc.) and the type of oil (conventional, synthetic blend, or full synthetic).
However, as a general guideline, many 2000 Mustang engines used 5W-30. But again, this is not a substitute for checking your owner's manual. Using the incorrect oil can seriously damage your engine.
