However, generally speaking, for most engines in that year's Sport Trac, you'd likely be looking at:
* 5W-20: This is a common viscosity for newer vehicles and is a good starting point if you can't find your owner's manual. However, always defer to the owner's manual first!
* 5W-30: This was also used in some Ford vehicles of that era, but again, check your owner's manual.
* Type of oil: The manual will also specify whether to use conventional, synthetic blend, or full synthetic oil. Synthetic is generally better for performance and longevity but more expensive.
Finding your owner's manual: If you don't have your owner's manual, you might be able to find a digital copy online through Ford's website or a third-party site that offers vehicle manuals. You can search using your vehicle's VIN number.
Don't guess! Using the wrong oil can damage your engine. Always refer to your owner's manual for the correct specifications.
