What Diesel Oil Does Ford Recommend? Unlocking Peak Performance for Your Truck

Choosing the right diesel oil for your Ford truck is crucial for optimal performance, longevity, and fuel efficiency. Ford has specific recommendations to ensure your engine operates at its best. In this comprehensive guide, we will delve into the world of diesel oils, exploring the types, specifications, and what diesel oil Ford highly recommends for your vehicle.

Understanding Diesel Oil Types

There are two main types of diesel oil:

• Mineral Oil: Derived from refined crude oil, mineral oil is a cost-effective option that provides basic lubrication.
• Synthetic Oil: Created from synthetic hydrocarbons, synthetic oil offers superior protection, extended drain intervals, and improved fuel economy.

Ford’s Recommended Diesel Oil Specifications

Ford recommends using diesel oil that meets the following specifications:

• API Service Category: CI-4, CJ-4, CK-4, or FA-4
• Viscosity Grade: 5W-40 or 15W-40
• Ford WSS-M2C171-F1: This specification ensures the oil meets Ford’s specific requirements for diesel engines.

Choosing the Right Viscosity Grade

The viscosity grade of diesel oil refers to its thickness at different temperatures. For Ford diesel trucks, the recommended viscosity grades are 5W-40 or 15W-40.

• 5W-40: Provides excellent protection during cold starts and high operating temperatures.
• 15W-40: Suitable for warmer climates and heavy-duty applications.
