When it comes to your 7.3 Powerstoke, this Ravenol synthetic oil assists with cold start activation. In fact, it can help your Powerstroke cold start in temperatures as low as -59 degrees Fahrenheit. This is all in addition to the fact that this oil keeps your Powerstroke lubricated while maximizing engine performance, fuel consumption, and cleanliness.
The high-oxidation formula reduces wear on your engine as you drive, and it prevents coke deposits, corrosion, carbon, and even sludge from forming. It even keeps your truck’s emissions clean by modern standards.
With all of that power in one synthetic diesel oil, it’s no wonder this Ravenol formula has so many endorsements from so many auto companies. It is undoubtedly one of the best oils for 7.3 Powerstroke engines around.
Schaeffer Manufacturing Supreme 9000 Synthetic Engine Oil
The Schaeffer Manufacturing Supreme 9000 full synthetic engine oil is a high-grade, high-quantity solution to keeping your 7.3 Powerstroke engine in top-notch condition long-term.
The entire formula of this oil is (see full specs) based on the idea of reducing friction. When you have Schaeffer Manufacturing’s Supreme in your 7.3 Powerstroke, there’s minimal heat and contact damage in the moving pieces of your engine.
Best of all, it hardly thins when it’s exposed to high temperatures, meaning you get the same great performance out of your engine without damage from sub-standard, ultra-hot oil. And if you’re running in cold temperatures, this oil lubricates even better than normal.
All in all, Schaeffer Manufacturing went out of their way to think of everything for this oil. Sold in a five gallon bucket, you’re sure to have plenty of Powerstroke oil for weeks, months, or even years — even if you run your pickup every single day.
Shell Rotella T4 Triple Protection Diesel Engine Oil
The Shell Rotella T4 triple protection heavy duty diesel engine oil is in the same “family” as the first oil on our list, but it’s different in a few key ways.
The first big way is quantity. This is a 55 gallon drum of Powerstroke motor oil (see full specs), making it ideal for commercial, industrial, or long-term residential buyers. Beyond that, this oil is suitable for any low-emission diesel engine, and it provides all of the outstanding protection benefits of the previous Rotella oil.
In addition, the T4 triple protection formula regulates acid and carbon buildup to reduce corrosion on your engine. As it works, it also keeps your emissions cleaner to low-ash, low-emission standards.
With so much working for this synthetic oil — and offered in such a huge quantity — this could be the only purchase you ever have to make for Powerstroke engine oil in your life. And if you want to use this oil for heavier-duty applications, it’s all yours for a reasonable price, compared to other oils.
Which is the Best Oil for 7.3 Powerstroke Engines?
Finding the right oil for your needs is as simple as figuring out what you want to do with your Ford pickup.
First, look at price. If you’re buying oil for yourself (as opposed to a business), you don’t need to go all-out on the most expensive, highest-quantity purchase you can find. You can do just fine with a more affordable oil in a smaller quantity. The opposite is true if you’re shopping for industrial or commercial applications.
Second, what do you want out of your oil? If you’re looking for straight-up lubrication, then you don’t have to look at the qualities of most synthetic oils for a 7.3 Powerstroke. On the other hand, if you know you’ve had trouble with engine wear, thinning oils, and other issues, take a look at the higher-grade oils for better results.
Finally, how much oil do you really need? Be honest with yourself. It would be cool to have a 55-gallon drum of oil in your garage — but do you really need it?
Once you’ve figured out these three factors, you’re clear to pick the best oil for 7.3 Powerstroke engines. Good luck!
