This engine requires synthetic oil, and Ford recommends full-synthetic. This type of motor oil is much better than the standard oils where reliance on old types like mineral based oils are becoming extinct as well.

When it comes to Powerstrokes, there is no better oil than synthetic. With its extreme heat and high pressure caused by the HEUI injectors in the 6.7L Powerstroke engines.

This can lead all other oils to fail miserably when protecting your engine against stiction and wear over an extended period of time due to their inability to prevent sludge build up on parts inside like pistons, rings, gears, housings, valves etc.

The best protection for the 6.7 Powerstroke will always come from relying on a full synthetic motor oil.

Ford recommends their own Ford Motorcraft oil, but there is a long list of diesel motor oils that comply with the Ford recommended standard.

Should I Use Synthetic Oil in my 6.7 Powerstroke?

6.7 Powerstroke owners have many different oil options to select from when caring for their engines, but it can be hard knowing which one is best suited for you specifically because there isn’t just one kind in this segment of the market!

There are three types: synthetic motor oils tailored towards diesel engines with high compression ratios like these trucks; mineral-based semi-synthetics made by companies such as Mobil1® or Valvoline® ; and conventional fluids designed mostly at lower speeds where they last longer than others due to being heavier viscosity ratings, but they break down quicker than synthetic oils.

Engine oils are a confusing topic. Engine manufacturers recommend changing your oil frequently, but some people might not be able to tell the difference between brands and styles so they just go with what feels best – which isn’t necessarily good for their truck.

Under normal use most engine oils will behave similarly; unless you’re using the cheapest possible product there’s no need to worry about noticing major differences among similar products in this case. But still my recommendation is always make sure you get high-quality fluids such as ones from name brand manufacturers.

Conclusion

A full synthetic oil will always out perform a synthetic blend or a conventional oil. In the long run you will always be better off with full synthetic.
