Ford Oil - Engine
  • Geniune OEM part

This aftermarket offering from Ford itself is meant for heavy-duty applications. The best part of using a genuine OEM fluid is that you can rely on the high quality and effectiveness of the oil without thinking whether the grade of oil would work in sequence with your truck.

Recommended particularly for Powerstroke applications

Meant for service and overworked Powerstroke engine trucks, Motorcraft’s SAE 5W-40 is particularly recommended if you use your truck for transport, construction, or hauling purposes. This high-performance motor oil has been formulated using synthetic base oils and provides decent control over soot. Motorcraft also claims to protect against rust, corrosion, and high-temperature oxidation and thickening. All in all, it’s a good choice if you drive a Powerstroke Super Duty or Chassis Cab series truck made from 2011 till now. 

Why do we like it?

This particular brand and grade of oil not only protects the exhaust after-treatment systems such as particulate filters from the old Powerstroke versions, but it’s also good for new generation motors which are low on emissions.

  • For best performance, follow the manufacturer's recommendations in your vehicle owner’s manual.

You can always count on Lucas’ Magnum line of oils to give you the ideal amount of wear protection and make the emission control systems in your truck last longer, thanks to the premium additives. It’s good synthetic oil that will keep up with how you use your truck and if the past is any indication, it gives the motor better oil pressure, as reported by many users.

Lasts twice as long as conventional 15W-40 oil

The additives used by Lucas are the highlight of this particular oil. You can expect less oil consumption and reduced engine wear if you happen to drive a high mileage truck. Lucas’ offering here is likely to make it quieter and smoother sounding than before. Overall, we’ve heard plenty of good things about it, but the packaging can be improved. There have been instances where buyers have received poorly packaged jugs leading to oil leaks. That said, this isn’t a common issue and certainly not a deal breaker so if you are looking for a long-lasting synthetic oil for your Powerstroke Ford pick-up (2011-present), Lucas’ Magnum 15W-40 synthetic oil is worth a try.

Why do we like it?

The key benefits of using this oil are reduced engine wear and oil consumption. Although it’s primary application is in heavy-duty diesel engines like Ford’s Powerstroke, it can also be used in gasoline engines, so if you also have a gas-powered truck, you can save time by buying in bulk and using the same oil for both engines.

Pros

Pros
  • Reduced engine wear and oil consumption

Cons

Cons
  • Packaging can be improved

  • For best performance, follow the manufacturer's recommendations in your vehicle owner’s manual.

When you spend so much on a Super Duty truck, you want it to last, and for that, you need to keep its motor lubricated with oil that’s specifically recommended for it. Motorcraft’s Super Duty 15W-40 is a fairly high-quality diesel engine oil formulated with hydro-processed base oils and unique additive technology.

Effective over a wide temperature range

Motorcraft’s XO-15W40 Super Duty oil is known to work well in normal and warm climates as well as cold regions. In fact, this oil is recommended for use in Powerstroke motors over a wide temperature range, from down to -20°F (-29°C) to up to 100°F (38°C). Speaking of compatibility, as its name suggests, this second option from Motorcraft is best suited to Ford’s Super Duty range of trucks from 2011 to present day.

Why do we like it?

Generally, the Powerstroke range isn’t tied to any particular grade of oil. They usually run rich with fuel at times so if you’re looking to opt for conventional (synthetic) motor oil, there is hardly a better option than this. It works well under wide temperature ranges and more importantly, it also effectively minimizes engine deposits and wear.

Pros

Pros
  • Suitable for both warm and cold weather running

Cons

  • Excellent wear protection during severe operating conditions
  • Oil durability: strong oxidation and viscosity control with less oil consumption
  • Better contamination control with superior soot-busting, deposit-dispersing capability
  • Strong stay-in-grade performance throughout the life of the oil
  • Friction modified with micron moly and penetrate

Schaeffer is among the better known oil brands out there and its 700 SynShield, although not fully synthetic, is a popular choice among Powerstroke users. This 15W-40 grade motor oil provides good durability and longevity even under harsh operating conditions. Using Schaeffer’s patented friction modifiers, the oil comes with a slippery, tenacious shield that prevents metal-to-metal contact. This added layer of durability protection reduces wear on bearings, rings, pistons, cylinders and valve trains.

Improved wear protection for durability

If you aim to keep or run your truck for years to come, Schaeffer’s 700 SynShield is probably your best bet thanks to its proven wear protection. The oil has been formulated to offer high degrees of protection against wear, oxidation, and deposit formation. In terms of real-world improvements, most of the users have seen their 6.7 Powerstroke hold much better oil pressure than other 15W-40 oils, which is always good. Sure, it costs a bit more than some of the other oils, but it’s worth the premium given its performance and the brand’s reliability. It’s suitable for use in all Powerstroke models that utilize heavy exhaust gas recirculation (EGR) and exhaust after-treatment devices such as diesel particulate filters (DPFs).

Why do we like it?

Besides being easy on the motor’s internals, Schaeffer’s 700 SynShield has superior low instability characteristics to control oil consumption. This basically means there is less oil loss in extreme conditions which results in efficient combustion.

Pros

Pros
  • Good for long-term usage
  • Improved wear protection
