* 10W-30 is a good all-around choice for most climates. It provides good protection in both hot and cold temperatures.
* 5W-30 is a better option if you live in a consistently cold climate. The lower "5" indicates better flow in cold temperatures, making starting easier.
* 20W-50 might be suitable for extremely hot climates or for an engine that's showing signs of wear, but it's generally thicker than needed for most situations.
Always check your owner's manual for the manufacturer's specific recommendation. The manual will usually provide a range of acceptable oil weights. Using an oil weight outside the recommended range can negatively impact your engine's performance and longevity. If you don't have the manual, you can often find a digital version online through a Ford parts website or a third-party automotive resource.
