The 6.7 Power Stroke diesel engine is a workhorse. But even the toughest engines need proper care. One of the most important maintenance tasks is changing the oil. Using the right oil and the right amount is key to keeping your Ford Super Duty truck running strong. This guide will tell you everything you need to know about oil changes for your 6.7 Power Stroke.First, let's talk about how much oil you need. This depends on when your truck was made. If your truck was built between 2011 and 2022, the oil capacity is 13 quarts. For trucks made after 2022, it's 15 quarts. Always double-check your owner's manual for the exact amount. Adding too much or too little oil can cause problems.Now, what kind of oil should you use? Ford recommends Motorcraft oils that meet a specific standard (WSS-M2C171-F1). This ensures the oil is designed for the demands of a diesel engine. Two common choices are Motorcraft 10W-30 and 15W-40. The right one for you might depend on the weather where you live and how you use your truck. Using the wrong oil could even void your warranty, so it's important to get this right.How often should you change your oil? Generally, every 50,000 to 75,000 miles. However, if you tow heavy loads or drive in extreme conditions, you might need to change it more often. When you change your oil, always change the oil filter too. This helps keep your engine clean and running efficiently. Again, using a Motorcraft filter is a good idea.One common question is about the slight differences in oil capacity reported by some sources. Some forums mention capacities as high as 17 quarts for newer models. It's always best to stick with the official recommendation in your owner's manual. This is the most accurate information for your specific truck.Another question is about using synthetic oil. Ford recommends fully synthetic Motorcraft oil for the 6.7 Power Stroke. Synthetic oil is designed to handle higher temperatures and provide better protection than conventional oil. This is especially important for diesel engines, which work harder than gasoline engines.Taking care of your 6.7 Power Stroke is an investment. By using the right oil and changing it regularly, you can help prevent costly repairs down the road. As engine technology continues to advance, staying informed about the latest recommendations is crucial. Always refer to your owner's manual and consult with a qualified mechanic if you have any questions. Keeping your truck properly maintained will ensure it continues to deliver the power and reliability you expect from a Ford Super Duty.
