Understanding The 6.7 Powerstroke 

The 6.7 Powerstroke diesel engine was officially launched in the market by Ford in 2011. With a 6.7 L capacity, this v8 turbocharged engine requires almost 13 quarts of motor oil for its smooth running.

The engine takes pride in delivering an impressive torque of 675 to 935 lb-ft and has a horsepower that ranges between 270 to 450 hp. Lastly, the net weight of this diesel engine is around 970 pounds. 

6.7 Powerstroke Oil Type

The 6.7 liter Power Stroke engine is a workhorse known for its durability and power. This engine requires 13 quarts of oil, which is a lot compared to other engines. For normal driving and use, owners should use 10W-30 oil.

If you frequently drive in colder temperatures or frequently tow heavier loads, then you might consider using 5W-40 oil. This oil is slightly thicker and will provide better protection for your engine in colder temperatures and when towing heavier loads.

Factors To Consider While Picking The Best Oil For 6.7 Powerstroke 

Now that you’ve got a clear understanding of how this engine looks, let’s find out what factors you need to keep in mind while purchasing the best oil for this 6.7 Powerstroke engine.

1. Oil Efficiency

One of the main aspects of lubricating oil is making sure that the engine’s metallic contacts are minimal. In addition to that, if the motor oil meets the specific requirements set by the manufacturing company, it’s said to be trustworthy, efficient, and compatible with your Powerstroke. 

Due to high temperatures and emission of combustion byproducts, your 6.7 Powerstroke requires high engine protection. This is why it is important to avoid the cheaper options and stick to high-quality motor oils. Furthermore, good quality oil prevents viscosity loss at high temperatures, boosts fuel economy, and keeps your engine running in good shape.

2. Viscosity

When it comes to lubricating oil’s viscosity, it indicates the level of high and low temperatures it can resist. In other words, the oil thickness plays a crucial role in selecting the right motor oil for your Powerstroke.

You need 5W -40 viscosity for heavy-duty vehicles and 15W -40 for biodiesel engine uses for smooth operations. For normal use of 6.7 power stroke engines, 10W -30 rating motor oil is the best choice. 

Also, based on the temperature change, the viscosity of the motor oil keeps varying. To prevent this from happening, manufacturers include improvers to the oil these days. Due to these additions, you will come across two grades of motor oil in the market. 

  1. Multi-grade engine oil: This option is suitable for high and low temperatures and is available as 15W -40 and 5W -40 options.
  2. Mono-grade engine oil: This type is classified into summer grades for warmer temperatures and winter for colder temperatures.

The above suggestions may vary based on your car model; hence it’s advisable to go through the user manual before making your final decision.

3. Additive Packaging

Certain types of additives are added to it to protect the engine oil from contaminants and keep it in top form for a long. Some of the additives that automobile manufacturers include are friction promoters, antifoam agents, antioxidants, anti-rust agents, and anti-wear products. 

While choosing the best oil for your 6.7 Powerstroke, in most cases, it’s packed with a superior additive that protects the engine from grime, sludge, varnish, contaminants, and harmful deposits.

Powerstroke engines are mostly used to drive around in rough terrains; it’s natural to accumulate in large quantities. Using motor oils packed with additives safeguards the Powerstroke from oil oxidation, acidity, and soot buildup.

On a positive note, you need not worry about scheduling a frequent oil changes by using engine oils designed for heavy-duty trucks. This is because it comes packed with superior additives that prolong wear and tear. 

Frequency of Changing 6.7 Powerstroke’s Motor Oil

Suppose you happen to be the proud owner of a heavy-duty truck or tractor. In that case, it is essential to conduct regular engine maintenance to extend the lifespan of your motor engine. 

But, most individuals are not aware of how often they should schedule these repairs. Due to advanced technology, most high utility cars have specially designed sensors that pop up notifications on the dashboard to indicate the next oil change schedule. 

If your heavy-duty vehicle is not equipped with this modern technology, it’s advisable to schedule an oil change every 5000 to 6000 miles for synthetic oils and 3000 miles for engines using standard oils. If your 6.7 power stroke engine uses full synthetic oil, then you can raise the bar and schedule the oil change after reaching 10,000 miles.

Final Verdict

To ensure good operating conditions for your 6.7 Powerstroke engine, you need to opt for high-quality engine oil that exceeds the requirements set by the automobile company.

Well, finding the right motor oil for your Powerstroke engine can be an overwhelming task. It is not only efficient but also complies with the green environment requirements of reducing the emission of harmful fumes into the environment. 

Though the 6.7 Powerstroke engine can use a wide range of quality oils, the best option for heavy-duty loads is 15W -40 oils. Besides, good quality lubricating oil also enhances fuel economy engine efficiency and reduces friction.

Since these motor oils are known for optimum viscosity and better efficiency, they are considered one of the best options for your 6.7 Powerstroke engines. 

However, make sure to change the lubricating oil at every 5K or 7K miles depending on the type of motor in your automobile. Or else, as time passes, your engine will start corroding, resulting in malfunctioning or complete breakdown.
