However, if you use your truck for heavy duty work, and the engine generates a lot of heat, you may want to look at other options with higher viscosity range.
Factors to Consider
Here are some important factors to look into and compare before buying engine oil.
Viscosity in simple words is oil’s thickness or its resistance to flow. So why is it important for 6.0 Powerstroke engines?
Because based on your weather and average temperature, you need to find oil with a viscosity that fits well with the weather or the heat your engine generates.
Most lubricants act differently for different temperatures. As the temperature of the engine rises, the viscosity decreases as the oil gets thinner with the rising temperature. Thin oil is not good for engines, especially powerful diesel engines like the 6.0 Powerstroke. This means you need an engine oil with a higher viscosity to stand the heat generated by these engines.
To help you learn about the viscosity of engine oil, Society of Automotive Engineers (SAE) has developed a standard. The standard viscosity code available with every engine oil tells you about the level of viscosity in both cold and hot temperatures.
The code is made of two numbers and a letter W (stands for winter) that separates these numbers. The number before the letter W represents oil’s viscosity at low temperature (0F), and the number after the W represents viscosity at high temperature.
For example, the code 5W30 represents oil with low viscosity (more fluid) for low temperature, which means it is easier for Powerstroke 6.0 engines to pump oil even in low temperatures, which makes cold starts easier.
You can buy the oil according to the temperature of the area you lives in or drive your truck according to the following chart:
- 5W-30/40 – 10W-30/40: for extremely cold weather.
- 15W-40: for moderate weather
- 20W-50: for moderate to hot weather.
As we mentioned earlier, most synthetic blends like Shell Rotella T5 contains additives. So what are these additives and what they do to your engine?
Additives are used to improve your engine performance and to make engine oil better. Keep in mind – the oil has to deal with engine temperature, combustion byproducts, moisture, corrosion, rust, and even unburned gasoline. They even have to work hard in high-performance engines like 6.0 Powerstroke engine.
To make oil perform better, oil manufacturers now mix additives in the blend, that help the oil with proper lubrication under different temperatures, and keep the damage from varnish and sludge to a minimum level.
Here are some common additives used in synthetic blends.
- Friction modifiers like molybdenum and graphite to help reduce engine friction to optimize fuel efficiency.
- Viscosity-index improvers that help oil maintains its viscosity under high temperatures.
- Antiwear agents that protect the metal surfaces in your engine when the lubricating film breaks. The most common anti-wear agent in use is ZDDP, a compound made of phosphorus and zinc.
- Detergents to remove mostly solid deposits but they don’t scrub the surface of your engine. They mostly resist the formation of rust, corrosion, and other deposits.
- Dispersants are used to disperse solid particles and to resist the formation of solid blocks. This way, your oil can prevent the formation of acids, varnish, and sludge.
- Other common additives include rust/corrosion inhibitors, foam inhibitors, antioxidants, and pour-point depressants (to help oil remain lubricant in low temperatures).
The good quality 6.0 Powerstroke oil can have an impact on the fuel economy of your truck. Similarly, the right viscosity can also help your engine save fuel. For example, if the engine oil is too thick, it will make it difficult for your engine to start, especially in winter, which decreases the fuel economy.
If the engine oil lubricates your engine well, keep it clean of deposits, resists against corrosion and rusting, and reduces friction, the fuel economy gets better. Simply put, the thicker it is, the harder it is for your engine to push it through other engine components, the more fuel it consumes.
So, the thinner it is, like 5W30, 5W40, or 10W30, the better fuel economy it offers. However, with powerful engines like 6.0 Powerstroke that generate a lot of heat, low viscosity oils are not always a good option.
Even though there aren’t any detailed automotive engineering studies that can give us a precise quantity about how much an engine oil can save on fuel, but the best guess is, thinner oils that are easy to push through engine have a positive effect.
Performance of Engine
Most synthetic oils contain additives, as described above, to keep your engine clean and to minimize engine friction, that improves your engine’s performance. The fuel additives also keep the injectors and other engine components clean.
The use of a high-quality 6.0 Powerstroke oil as well as on time oil change is the best thing you can do to not only boosts your engine performance but also to extend the life of your engine oil.
Similarly, oil sludge produced mostly because of using old oil can also affect engine performance. The thicker it gets, the more effort your engine has to make to push it around. However, engine issues can be diagnosed using an OBD2 tool.
Last but not least, cost is another important consideration. Conventional oils are cheapest, while synthetic blends and full synthetic oils are expensive, depending on the additives and the types of synthetic oils used.
How to Change Oil in 6.0 Powerstroke Engine
You don’t always have to go to a mechanic to change engine oil. Once you have the best Powerstroke 6.0 oil with you, you can do it on your own by following a few simple steps as described below.
You only need a few basic tools with you that include 36mm socket, 19mm socket, and a flat screwdriver.
Step 1: Get under your truck and find the drain plug that is available at the center of the truck, between the driver and passenger seat.
Step 2: Use the socket to open the drain plug and make sure you have a pan placed below it that can hold at least 15 quarts of oil. Let it drain completely.
Step 3: Remove the oil filter using the 36mm socket which you can find in the center of the engine. You can pull it out easily but hold it for a few seconds to let the oil drain.
Step 4: Go back underneath the truck again, put back the drain plug back. Now, install the oil filter. First, remove the ring from the oil filter cap using a screwdriver and replace it with a new one.
Step 5: After that, push the new oil filter into the cap. Before placing the cap with new filter back over the filter spring, pour some oil in there. Now, place it over the spring, push it, and tighten the cap screw back.
Step 6: Find the oil filler at the back of the engine, remove its cap, fit a funnel, and pour the remaining 6.0 Powerstroke oil (14-15 quartz). Check the oil dipstick and see if the oil level is in between the two marks.
Wrapping up – Best 6.0 Powerstroke Oil
If you are using the best engine oil with your 6.0 Powerstroke engine, you not only have to visit mechanic less but on time oil change after every 5000 miles will also extend the lifespan of your engine. Mostly synthetic oils that are considered best for these engines.
Keep in mind, 6.0 Powerstroke engine is a high-performance engine, that generates a lot of heat. You need 6.0 Powerstroke oil with comparatively wider viscosity range, like Mobil 1 44986 or Liqui Moly 2041 Premium, that is also good for fuel economy.
However, a lot depends on the weather and the environment you use your truck in. If you use your truck in colder areas and for general purpose, the above oils work excellent. If you live in comparatively hot areas and use your truck for heavy duty work that makes the engine work harder and generate more heat, options like Valvoline Premium Blue and Shell Rotella T5 are better.
