* For most climates: 5W-30 is a common and often recommended weight.
* In hotter climates: 10W-30 might be preferable.
* In colder climates: 5W-20 might be suitable, but again, *check your owner's manual*. Using a weight too thin in hot weather can lead to engine wear.
Always use an oil that meets or exceeds Ford's specifications as listed in your owner's manual. The manual will also specify the correct oil type (conventional, synthetic blend, or full synthetic).
