What oil is recommended for Ford diesel?
Choosing the right oil for your Ford diesel engine is crucial for maintaining its performance, longevity, and efficiency. With years of experience in car maintenance and repair, I’ve seen firsthand how using the correct oil can make a significant difference in engine health. In this article, I’ll guide you through the recommended oil types for Ford diesel engines and why they matter.
Why the Right Oil Matters for Ford Diesel Engines
Diesel engines operate under higher compression and generate more heat compared to gasoline engines. This means they require oil that can withstand extreme conditions while providing adequate lubrication and protection. Using the wrong oil can lead to increased wear, reduced efficiency, and even engine damage over time.
Recommended Oil for Ford Diesel Engines
Ford diesel engines, such as those found in the Power Stroke lineup, typically require oils that meet specific standards. Here’s what you need to know:
- Viscosity Grade: Ford recommends using oil with a viscosity grade of 10W-30 or 15W-40, depending on the operating temperature. For colder climates, 10W-30 is preferred, while 15W-40 is suitable for warmer conditions.
- API Certification: Look for oils that meet the American Petroleum Institute (API) CK-4 or CJ-4 standards. These certifications ensure the oil is designed for modern diesel engines and provides excellent protection against wear, deposits, and oxidation.
- Ford Specification: Always check your owner’s manual for the specific Ford specification required. For example, many Ford Power Stroke engines require oil that meets the WSS-M2C171-F1 specification.
- Synthetic vs. Conventional: Synthetic oils are often recommended for their superior performance in extreme temperatures and better engine protection. However, high-quality conventional oils that meet the required specifications can also be used.
By adhering to these recommendations, you can ensure your Ford diesel engine operates smoothly and efficiently, even under demanding conditions.
How to Choose the Best Oil for Your Ford Diesel Engine
When selecting oil for your Ford diesel engine, consider the following steps:
- Consult Your Owner’s Manual: This is the most reliable source for determining the correct oil type and specifications for your specific engine model.
- Check the Label: Ensure the oil meets the required API certification and Ford specification.
- Consider Your Driving Conditions: If you frequently tow heavy loads or drive in extreme temperatures, opt for synthetic oil for added protection.
- Stick to a Trusted Brand: Brands like Motorcraft (Ford’s official oil brand), Shell Rotella, and Mobil Delvac are popular choices for diesel engines.
Following these steps will help you choose the best oil for your Ford diesel engine, ensuring optimal performance and longevity.

Frequently Asked Questions
What diesel oil does Ford recommend?
The manufacturer recommends 10W-30 for normal usage and 5W-40 for severe operations.
What is the best oil for a 6.7 Powerstroke?
The ONLY SYNTHETIC oil specified by the workshop manual for the 6.7L Power Stroke engine is Motorcraft® SAE 5W-40 Full Synthetic Diesel Motor Oil. Motorcraft® SAE 10W-30 Super Duty Diesel Motor Oil is considered the standard oil to be used in this engine and is identified specifically on the engine oil fill cap.
What kind of oil does a 3.0 Powerstroke take?
Engine Oil
Viscosity: 0W-40 (All TEMPS) - For Normal Service the OEM Recommends the use of FA-4 SAE 5W-30 or SAE 10W-30.
What brand motor oil does Ford recommend?
Motorcraft®
What is the recommended engine oil for my Ford? Ford recommends using Motorcraft®* motor oil for your Ford vehicle. Using the right oil helps keep your vehicle's engine clean, reduces overall wear, and maximizes performance.
Can I use 15W40 instead of 10w30?
In hot climates, where engines can reach high temperatures, 15W40 oil's superior high-temperature protection would be advantageous. Conversely, in cold climates, 10W-30 oil's improved cold-start performance would be beneficial.
Is 15w40 oil good for diesel engines?
Both 15W-40 and 10W-30 oils are multi-grade oils commonly used in diesel engines. The numbers in their names refer to their viscosity at different temperatures. The “W” stands for winter, indicating the oil's performance in cold weather, while the numbers reflect its viscosity at high temperatures.
Is Shell Rotella T6 approved by Ford?
The approved oils – Shell ROTELLA T4 15W-40 Triple Protection, Shell ROTELLA T5 10W-30 Synthetic Blend and Shell ROTELLA T6 5W-40 Full Synthetic – meet Ford Material Engineering Specification WSS-M2C171-F1.
Is Shell Rotella T6 good for diesel engines?
Shell Rotella® T6 can help improve the fuel efficiency of your vehicle. Developed in close cooperation with leading engine and vehicle makers, it not only offers possible fuel-economy benefits*, but also the durability and performance demands of the latest low-emission diesel pickups.
What happens if I put 10w30 instead of 15W40?
While the viscosity of a heavy duty engine oil accounts for its contribution to fuel economy, it is the composition of the base oil and additives that protect your engine from wear, soot and acid. Since 10W-30 is thinner than 15W-40, its film strength can be weaker and it can be more prone to oxidation.
What is the best oil to use in a diesel engine?
Diesel engines generally require oils with higher viscosity, often denoted by numbers such as 15W-40 or 10W-30. The first number (15W or 10W) indicates how the oil performs in cold temperatures, while the second number (40 or 30) indicates its performance at high temperatures.
