Here's why:
* 5W-30 is the recommended oil weight: This is the factory recommendation and ensures proper lubrication across a range of temperatures.
* 10W-30 is also acceptable: While not the factory recommendation, 10W-30 is compatible with the engine and offers decent performance. It might be a better choice in hotter climates.
* 10W-40 is NOT recommended: Using a thicker oil like 10W-40 can lead to increased wear on engine components, especially in colder temperatures.
Important Notes:
* Consult your Owner's Manual: The most accurate information will always be found in your vehicle's owner's manual.
* Consider your Climate: If you live in a very hot climate, 10W-30 might be a better choice. However, using 5W-30 is generally recommended for most climates.
* Use High-Quality Oil: Regardless of the weight, always use high-quality motor oil that meets the specifications in your owner's manual.
To find the exact specifications for your vehicle, check the owner's manual or visit the Ford website.
