Powerful diesel engines and 6.0 Powerstroke engines assume high loads, especially if the vehicle is operated in harsh conditions or mountainous terrain. High-quality synthetic oils help protect the engine at such loads. These oils have high viscosity when heated and good fluidity when cooled.
In terms of viscosity and density, the best oil for 6.0 Powerstroke is 5W-40. There are also high-quality semi-synthetic oils but we will consider the best synthetic products with several effective properties.
The advantage of using synthetic oils over conventional oils is that they have high stability, excellent viscosity, and low decomposability. These oils do not require frequent changes and can stay effective for more than 10,000 miles, even in old vehicles. Thus, the replacement interval is increased. and the oil’s properties remain even with high mileage.
This applies to oils from proven manufacturers, which, of course, have their price. Cheap oils are unlikely to provide adequate protection for a powerful diesel engine, consequently, it makes no sense to save heavily on oil.
5W-40-marked oils are intended to be used in winter but they are suitable for any season due to the fact that they retain their properties in a wide temperature range. For example, Valvoline Premium is a versatile option, which is used in diesel and gasoline engines on various automotive equipment. As a rule, such oils harden below -40F, which allows starting the engine in the cold without any negative consequences.
Each oil in this article has its exact viscosity indexes and cleaning properties but in general, all of them perfectly protect an engine from overheating and excessive clogging. Opt for high-quality lubricants from the best manufacturers to maximize your engine’s life.

Frequently asked question
Mobil 1 is the best choice for a 6.0 Powerstroke. With this oil, the engine will not overheat when towing or hauling heavy loads at long distances. The oil allows the engine to operate safely at ambient temperatures, ranging from -22F to 104F. It effectively cleans the engine inside and does not allow its parts to overheat due to intense friction. Moreover, there is no need to change the oil too often.
6.0 Powerstroke engines are best “fed” with 5W-40 or 15W-40 oils. The difference between these two options lies in the lower temperature range. 5W-40 operates at temperatures down to -22F, and 15W-40 can only function at -4F. This should be taken into account when choosing winter oil for your vehicle. Oils with other viscosity are not recommended, as they lose stability and density in such powerful engines, especially at high temperatures. As for the recommended oil brands, it can be a product from any manufacturer with specified viscosity. It’s better if it’s a purely synthetic oil with stable properties at all temperatures.
Ford produces engine oils of various viscosities for its vehicles – of course, it recommends its own oils. Ford oils have excellent quality but the prices are often quite high. As a rule, they are synthetic or semi-synthetic oils that provide full protection of Ford engines. However, there are many other high-quality oils on the market, which are strong competitors of Ford oils. If we consider 5W-40’s viscosity, the Valvoline Premium or Shell Rotella’s T6 oils are superior to Ford products at some points. These oils are designed for heavy-duty diesel engines and provide not only engine protection but also increased performance, fuel efficiency, and reduced emissions.
Vehicle engines between 2005 and 2007 show the highest performance. These engines are more reliable and run up to 500,000,000 miles. However, there can be some problems with oil leakage in high-pressure oil supply systems. In fact, the best 6.0 Powerstroke engine issue is more about preferences than performance and availability. All 6.0 Powerstroke engines offer excellent endurance and performance.
