Top 5 Synthetic Oil for Ford 6.7 Diesel

Shell Rotella T – Best Full Synthetic Oil for Ford 6.7 Power Stroke Diesel

Shell Rotella’s T6 is the first item on our list of the top synth oils for the 6.7-lit V8. It is adaptable because it comes in various sizes, quantities, and packing. Additionally, it guarantees a gain in mileage, which is always good news, particularly over the long term. And to top it all off, this oil offers excellent resistance to temperature variations. As a result, it remains constant, no matter how hot or cold it is outside.

It shields the engine against dirt, deposit build-up, and other impurities because it is made with superior ingredients. The drawback is that this is one of the priciest aftermarket oil brands. Therefore, if money is an issue, you might do better with the other items on the list. But it will be a wise investment because it is a high-quality lubricant.


  • Compatible with exhaust emissions control systems
  • Protection against extreme operating temperatures
  • Fuel efficiency performance


  • It is expensive

Ford – Best Super Duty Diesel Synthetic Oil for 6.7 Powerstroke

This top-tier synthetic oil developed by Ford is next on the list. It was created to fit heavy-duty engines perfectly. By the way, the company’s engineers endorse it, which will last longer than any other product on the market. Most standards are met and exceeded by the XO-15W40 oil.

The improved compatibility is another noteworthy aspect. Both more recent and older engines can benefit from this lubricant. So, you can use it to power your reliable old truck for off-roading and your brand-new SUV for cruising. The drawbacks include some drivers’ reports of minor quality control problems. For instance, jugs frequently arrive late, and containers often lack their API seals.


  • Ford Motors’ recommendation for the 6.7-lit V8
  • Most big-brand standards are met and exceeded.
  • Compatible with both modern and vintage motors


  • Minor difficulties with quality control

Valvoline – Best Engine Oil for 6.7 Powerstroke

A particular mixture and consistency are necessary for heavy-duty vehicle engines to perform to their most significant potential. And using Valvoline Premium Blue oil will give you just that. In addition, TBN retention and superior oxidation resistance provide a long oil life. A quick reminder: Valvoline is a US-based firm, and this oil is 100% American-made and was created with the 6.7-liter V8 engine and American roads in mind.

However, be aware that if your engine is a first- or second-generation Powerstroke, this oil could not be of much use. Naturally, it will continue to function, but not as well as with the more modern motors. That is made up for by long-lasting lubrication, a reasonable price (this is a synthetic blend, not a pure synthetic), and first-rate customer service.


  • A fantastic option for heavy-duty trucks and SUVs
  • Exceptional shear stability and resistance to oxidation
  • 100% American-made goods


  • A poor option for older engines

Delo – Best Diesel Oil For 6.7 Powerstroke

This diesel oil stands out from the other lubricants on the list today because of its affordability. Delo 400 is right up there with the best high-grade oils for the money. Additionally, it lowers operating expenses. The company’s ISOSYN technology was used in the formulation of the lubricant. High-performance additives ensure that important engine bay components are safeguarded. They also effectively disperse soot and stop deposit build-up.

Additionally, this oil performs superbly with ultra-low, low, and regular sulfur diesel fuels. But be careful—if you don’t take care of it right, it can leak. Despite this tiny drawback, you should still put Delo on your list of essential items. It comes in three packs and should last for around a year, just like the Shell Rotella oil.


  • Covers a variety of sulfur diesel fuels
  • Uses the ISOSYN technology for protection
  • Very affordable price


  • May leak a little (nothing too serious)

6.7 Powerstroke Oil Capacity

Knowing how much oil to add when changing the oil in your 6.7-liter diesel Power Stroke is essential. Too much or too little fuel will prevent the engine from operating at its best and may potentially seriously harm the engine. So, let’s look at how to add oil to your engine correctly. Thirteen (13) quarts of oil are needed for the 6.7-liter Power Stroke diesel engine. Owners should use 10W-30 oil for everyday driving and usage. However, you might want to think about using 5W-40 oil if you routinely drive in cooler weather or frequently pull heavy loads.

Using the wrong type of oil can have disastrous effects on any engine, whether it is a 6.7-liter diesel Power Stroke or any other car engine. As with any oil change, it’s vital to use the right kind and amount of oil for your 6.7 diesel Power Stroke engine. Your engine’s performance may suffer if you use too much or too little engine oil. If you use too little engine oil, your engine won’t have enough lubrication. As a result, the engine may overheat; as a result, it seriously damages it.

Additionally, applying too little oil will make the engine perform less effectively, affecting your ability to save on fuel. Conversely, the oil can foam if you overfill your engine with oil. Therefore, avoid overfilling your car engine as this can harm the engine.

Stick to the 13 quarts of oil the dealer suggests when performing the oil change yourself. It’s also crucial to select an oil viscosity that matches your driving style. For example, you can get away with using 10W-30 engine oil if you use your 6.7-liter Power Stroke for light duty tasks like commuting to work and light towing or hauling. However, you might want to switch to 5W-40 oil if you frequently travel in colder climates or do a lot of pulling and carrying. This crucial choice will guarantee that your engine is properly oiled and capable of performing at its peak.
