Everyone knows that Ford’s Powerstroke diesel engines are some of the most dependable ever made. When it comes to durability and fuel efficiency, gasoline engines can’t even come close to the 6. 7 Powerstroke’s output, and even horsepower is up for debate.
Diesel engines require frequent maintenance and the use of the correct engine oil. Hence, our top 10 list of the finest engine oils for 6. 7 liter Powerstrokes has been put up.
Because Motorcraft Synthetic Lubricant is Ford’s only recommended oil for the 6. 7L Powerstroke diesel engines, we highly recommend using it.

1. Motorcraft Synthetic Engine Oil
Any manufacturer can compete for spots 2 through 10, but the top honor must go to Motorcraft Synthetic Oil. Ford owns Motorcraft, so it’s no surprise that they’re the only brand they suggest.
Other car manufacturers have their own oil and fluid brands, as well as other maintenance items, thus this relationship between the two corporations is not unusual at all.
Mechanics at your local Ford dealership should be using Motorcraft oil in your truck’s regular maintenance cycles because it was installed at the factory.
If you’re going to stick with the same brand and keep up with the planned maintenance, it makes sense to do so. Between $4. 5 and $7.5 a quart, Motorcraft’s diesel synthetic oils are comparable to the cost of most other alternatives.
2. Valvoline Full Synthetic Engine Oil
Using Valvoline synthetic oil for diesel engines is a no-brainer because of the brand’s reputation and the quality of its product. The Valvoline name was trademarked in 1873 by this American company, which has been in business since 1866.
Most BMW, VW, Mercedes Benz, Audi, and Porsche automobiles use Valvoline synthetic oil since the company has nearly perfected the synthetic oil manufacturing process. Extra wear protection and detergents prevent sludge and deposits from accumulating in their oil.
It costs $79 for three boxes of five quarts each, or $5.26 per quart, to get the greatest offer. Oil of this quality is reasonably priced and comes with 2 quarts of reserve capacity, so you’ll never run out.
3. Mobil 1 Extended Performance Motor Oil
The presence of Mobil 1 at the top of this list should come as no surprise. The Extended Performance motor oil from a leading motor oil company is great for 6. 7 Powerstrokes.
No other oil company can guarantee that their product will keep running for as long as the Extended Performance oil does.
Although you should follow Ford’s suggested service plan, Mobil 1 oil shows how long-lasting it is. The sophisticated synthetic mix protects the engine block from deposits and sludge formation while also providing superior lubrication.
It costs $24. 5 to buy five quarts of Mobil 1 oil, which works out to little under $5 a quart. Even if you can’t get a bulk bargain, Mobil 1 oil can still be one of the best and cheapest choices.
4. Pennzoil Platinum Euro-L Fully Synthetic Motor Oil
You can use Pennzoil Platinum Euro L oil in a 6. 7-liter Powerstroke even though it was designed for European automobiles. Unlike other synthetic oils, Pennzoil’s oil is generated entirely from natural gas rather than crude oil.
As a high-quality product, Platinum oil keeps pistons clean, maintains fuel economy and power over the course of the oil’s lifecycle, and can withstand extremely high temperatures.
Priced at $48.5 for a 6-quart container, Pennzoil Platinum Euro oil is expensive at $8 per gallon. Pennzoil Ultra Platinum costs just $5 per quart and works nearly as well as Euro L. if that’s too pricey for you.
5. Lucas Oil CJ-4 Synthetic Motor Oil
One of Lucas Oil’s core business tenets is to provide customers with high-quality products at a fair price.
Premium Lucas additives are added to their oil in order to keep pollutants low and meet with requirements set on the 6. 7-liter Powerstroke It’s a big plus that the maker says the engine will use less oil and last longer.
In comparison to standard oil, Lucas oil has double the amount of detergents, allowing for twice the amount of contamination while maintaining the same level of lubrication and wear resistance. Lucas Oil’s $32 gallon price tag makes it one of the most cost-effective options on the market.
The Lucas Oil company is a wonderful alternative if you don’t like the big brands due of their environmental and human rights impacts.
6. Shell Rotella T T5 Synthetic Blend Diesel Engine Oil
- 7 Powerstroke engines run on Shell Rotella oil, which is designed for heavy-duty gas and diesel trucks. High mileage synthetic mix oil is a big advantage for a truck that travels so many miles in a year.
The oxidation stability, low-temperature qualities, and enhanced volatility avoid engine damage even in the coldest of conditions..
As a matter of fact, Shell’s Rotella is specifically engineered to meet the needs of diesel vehicles and big rigs, and that should be enough to persuade customers.
Because it’s the only oil marketed particularly for vehicles, I allowed it a little wiggle room and put it at number six on the list.
7. Liqui Moly Longtime High Tech Synthetic Motor Oil
Although Liqui Moly is a well-known German producer, it hasn’t yet achieved widespread awareness in the United States, which is a shame considering the quality of their motor oils.
Lubricants, oils, additives, chemical solutions, and other vehicle servicing goods are the company’s specialty. They have over 4, 000 goods to choose from at reasonable prices.
The 6. 7 Powerstroke engine works perfectly with the Longtime High Tech oil, which is designed for use in vehicles with a DPF filter. For diesel oil, the price of the 5 liter canister (about 5 quarts) is $47,60.
Liqui Moly oil would have been higher on the list if it were less expensive, but it is currently 7th on the list due to its current price.
8. Castrol 03559 Edge C3 Advanced Full Synthetic Motor Oil
As the company’s best full synthetic oil, Castrol Edge advanced motor oil makes use of fluid titanium technology to enhance performance. Castrol, a well-known manufacturer of dependable motor oils, stands by its claims of better high-temperature performance, wear protection, and fuel economy.
Castrol’s $9-per-quart price, even in bulk purchases of 15 quarts, does not justify the significantly higher cost than its competitors. If you’ve had good luck with Castrol in the past, by all means stick with it, but if you’re on a budget, consider one of the other solutions on this list.
9. Pentosin Pento High-Performance Full Synthetic Engine Oil
Pentosin has been in use for about a century. As a modest German oil company, it rapidly became a household name around the world. It has a long service life and provides excellent lubrication and wear protection from the first to the last mile thanks to the Pento High Performance synthetic oil’s synthetic composition.
In a 6. 7 Powerstroke, Pentosin oil has been approved by numerous European automobile manufacturers. One of the most costly full synthetic oils on the market, it costs $11 a liter for a liter.
10. Amsoil Signature Series Synthetic Motor Oil.
It is an all-American product that blends high-quality synthetic oil with unique additives for long-lasting protection of the engine. The manufacturer’s warranty is one of the finest in the industry, with a 25-mile or one-year longevity guarantee.
However, even with all the durability, Amsoil’s Signature Series oil still costs over $100 a gallon. If it goes on sale frequently, I’m sure it’s still too pricey to compete with the big names both in price and quality, even at 50% off.
