Oil For Ford 6.7 L Diesel Recommended by Manufacturer
The 6.7 liter Ford Powerstroke diesel engine was introduced in the 2003 Ford F-Series Super Duty trucks and is currently in use in the 2010 model year. This engine has become notorious for issues with proper care and maintenance, most particularly related to oil changes and engine wear and tear.
The manufactures recommended service intervals for this engine are every 5,000 miles or six months under normal driving conditions. However, depending on the size of your diesel truck’s fuel tank, this may not provide you with enough oil changes to prevent serious damage.
It is also important that you use the proper oil for your specific engine, especially considering that Ford’s guidelines have changed over the years for this particular engine. The type of oil needed depends on the year your 6.7 liter Powerstroke diesel engine was made, so be sure to follow the guidelines properly in order to avoid costly repairs or replacements for this expensive vehicle.
SPECIFICATION
SAE 0W-30/0W-40 API CJ-4 meeting Ford Recommends Amsoil Max Duty Signature Series 0W-30/40 diesel oil.
VISCOSITY GRADE
Manufacturer recommends for biodiesel fuel synthetic 0W-40, 5W-40 or 15W-40 oil is recommended.
CAPACITY
The Ford 6.7 Powerstroke oil capacity is 13 quarts. Your oil needs to be replaced eventually. Every 5,000 to 10,000 miles is a good rule. If you don’t replace it, there will be issues with the engine.
Oil For Ford 6.7 L Diesel by Mileage
By law, all diesel engine manufacturers must specify brand and viscosity of lubricant for each vehicle model and year. The recommended lubricants are almost exclusively diesel engine specific petroleum based oils with certain additives to provide protection against soot, ash and other undesirable byproducts of the combustion process. These high quality multi-grade oils which contain chemical “Viscosity Index Improvers” improve the viscosity index of mineral base oil, hence their description as “Synthetic” oil.
A diesel engine must be properly “tuned” for the type of fuel used and the viscosity of oil recommended. If oil viscosity is too great, there can be a lack of atomization (vaporizing) in the combustion chambers and if it is too thin, incomplete combustion and engine overheating can result.
High-Mileage oil is a special blend of synthetic base oils and additives that is formulated to protect the engine as well as the transmission, power steering system, and other vital components from wear at high mileages.
When it comes to engines with over 100,000 miles on them, there are three kinds of damage that start happening: oil breakdown, deposit buildup, and gear damage, thats why you should consider your car’s mileage while picking the oil.

The Ford 6.7 Powerstroke oil capacity is 13 quarts. Your oil needs to be replaced eventually. Every 5,000 to 10,000 miles is a good rule. If you don’t replace it, there will be issues with the engine.
SERVICE INTERVALS
The diesel engine in this vehicle has a displacement of over 427 cubic inches and is capable of producing an enormous amount of power, more than enough to make it one very powerful machine. With such a huge engine comes many different parts and also increased wear and tear on these parts. A common question that everyone asks themselves when inquiring about the best oil for their diesel truck is; how often do I need to change my oil?
Changing oil every 5,000 to 10,000 miles is recommended. But the exact interval is no easy answer to that question because there are many factors that go into consideration when trying to determine how often someone should get their oil changed. If your driving consists mostly of long-distance trips then your oil should last longer than if you were to do short trips. Also the overall condition of your engine will affect how often you should change your oil . Some other major factors that play into the frequency of which someone should get their oil changed are; The size of the engine, where you drive, and how old or new the engine is.
If you live in an area where it rains frequently for long periods of time than this can also play a large part in how often you need to change your oil . Allowing dirt into the inside parts of your vehicle through your air intake system can cause wear on your cylinders and pistons therefore requiring more frequent changes.
There are many different types of synthetic oils available today but finding one that is best suited specifically for your Ford 6.7 L Diesel can be a bit of a challenge at times given the large amount of different kinds of oils available on the market today. However, there are some brands that have worked hard to perfect their oil formulations specifically for diesel engines . These are often high quality synthetics that can be purchased in various viscosities to fit virtually any driving condition or need.
HOW TO CHANGE OIL IN Ford 6.7 L Diesel?
Oil change is one of the easiest car maintenance works you can do. It’s really simple, however there is some preparation required before you do it yourself.
The best thing about Ford 6.7 L Diesel engine is that they are easy to work on and maintain with their modular design – meaning most parts are modular (plug-able). Ford F-Series Super Duty trucks share the same V8 or V10 engines as well as many other cars in Ford line up. One of the main benefits is that you don’t have to perform oil changes too often, especially if you use quality synthetic oil . However for any diesel owner regular maintenance is important to extend the life of your vehicle.
If changing your own oil seems like too much for you there are services that can help you. It’s worth mentioning that changing oil is not an expensive service and it will save you money in the long run if you change it by yourself.
Step 1. Prepare all the necessary Tools
You don’t need any additional tools to do the job, however make sure your vehicle has enough oil. There are different types of filters available on the market, use manufacturer recommendations when in doubt.
Step 2: Prepare The New Oil
Before you open the hood make sure to prepare new oil for your Ford 6.7 L Diesel engine. It’s recommended to warm up the engine before draining the old oil, but never start it in cold state due to risk of damaging diesel engine (if drained too early or not hot enough).
You can use ramps or jack stands depending on how much your vehicle weights and what is suitable for you – just remember that safety comes first!
Step 3: Drain Old Oil Out Of Your Vehicle
Now go under the car and locate oil drain plug – it looks like a regular hexagon bolt often located at pan undercarriage. Using wrench loosen it, but don’t remove – just leave the bolt in the hole so it won’t get lost.
Step 4: Add New Oil Into Your Vehicle
Now put the funnel into the oil container and start pouring in new oil. You need to add engine oil total without overfilling, but you will have to do some trial and error since it’s not easy to see when all old oil is out of your vehicle. Don’t forget that adding too much will increase power steering fluid loss , if that happens you can top off with regular power steering fluid . After all new oil is added simply re-tighten drain plug (recommended torque 40 ft lbs) and that’s it! Now you can take out the funnel and dispose of oil into old container. Please check your owner manual for recommended type and weight of oil since Ford F-Series Super Duty diesel engine require very specific specifications – such as ILSAC (International Lubricants Standardization and Approval Committee) GF5 or GF3+ . These oils are often very expensive, but they provide optimal protection for this engine type.
Tips
- Replace oil drain plug and make sure you’ve tighten it securely
- Replace only with the new filter
- Always clean everything around after you’ve done the step
- Apply a thin layer of clean engine oil to the gasket of the new filter
- Install new filter and torque to specifications
- Pour in recommended amount of engine oil
- Start engine and check for leaks
- Repeat steps as necessary at scheduled intervals
