Oils for 6.0 Powerstroke: 15W-40, 5W-40, 0W-40 – Which is the Best?

Motor oil replacement is known to be seasonal. When cold weather approaches, many drivers will have a headache – they need to choose oil for winter. Winter operation is a severe test for a vehicle’s engine.

Rapid temperature drops, impact loads during cold starts in freezing weather, large amounts of road salt in a blend with the tiniest particles of sand in the engine – all this imposes special requirements to engine oil in winter operation.

It so happens that “winter” preference is traditionally given to “semi-synthetic.” Why? Many car owners justify it by the moderate price of oils of this group, with a sufficiently high level of quality. Moreover, there is a widespread opinion that semi-synthetic motor oil is the best option for any season. Is it right?

Let’s make this clear at once – despite the widespread popularity of semi-synthetic oils, it is worth noting that “semi-synthetic” is, however, a more or less successful compromise between price and quality, depending on the oil composition and quality level of a particular brand.

The main thing for engine oil in winter is high cold start characteristics and maximum thermal/chemical stability. Mineral engine oils are able to provide standard starter crankshaft “turnability” at engine start, up to a temperature not lower than 5F/-4F. But it can be much colder in North Dakota! Synthetic oils retain excellent cold start characteristics from -22F to -40F.

At the same time, according to various engine test results, using synthetic oils with viscosity grade SAE 5W-40, engine part wear at cold starts at -4F will be about 200 times lower than when using mineral engine oil SAE 15W-40! A cold start with mineral oil in such weather equals to 125-190 run miles. Multiply this by cold starts, and you will get an impressive economy on “synthetics.”

How do semi-synthetic oils look like here? To start with, the share of synthetic components in such oils does not exceed 10-30%. All the rest is mineral oil and additives. Naturally, with such a percentage of components, you should not expect any sharp improvement in cold-resistance and starting characteristics of “semi-synthetics” in comparison with quality mineral motor oils.

Starting qualities of semi-synthetic motor oils are only 5F better than those of mineral motor oils. Plus, the congelation temperature of SAE 15W-40 and SAE 10W-40 oils is practically the same!

Besides, semi-synthetic motor oils practically do not differ much from mineral oils in their resistance to oil base damage. And if in summer, this difference is more or less noticeable, then in severe winter conditions, the difference actually goes to zero.

Still, we should admit that the best oil for winter is fully synthetic. How do such oils differ from mineral and semi-synthetic?

The difference is mainly in the molecular structure of the oil base. In the process of synthetic oil production, molecules with the set, optimal operating properties are “built” (synthesized). Synthetic oils, in contrast to mineral oils, have maximum chemical and thermal stability.

Chemical stability means that when synthetic oils operate in the engine, there are almost no chemical transformations (oxidation, aging, etc.) that degrade its performance and lead to its destruction.

Thermal stability is the preservation of the optimal oil viscosity value in a wide temperature range, an easy and safe cold start, and at the same time, maximum engine protection in its highest temperature zones at high speeds and loads.

Due to the peculiarities of their molecular structure, synthetic oils have higher (compared to mineral and semi-synthetic) fluidity and penetration ability. Enough to say that the full synthetic oil engine lubrication process at cold starts does not exceed 40-50 seconds, while standard mineral oils can require several dozens of minutes!

Thus, by using really high-quality synthetic engine oils, you will protect your engine and provide a truly long service life.


Types of Engine Oil


  • Semi-synthetic oil is a lubricant which has mineral substances, produced as a result of oil refining, added to its composition in minimal quantities.
  • Fully synthetic oil is a lubricant, the lubricating substances which are fully obtained as a result of oil refining.
  • Mineral oil is a lubricant where materials are produced by purification of oil, unlike other groups where lubricants are created artificially in laboratory conditions.
  • Hydrocracking oil is a lubricant that contains improved lubricating minerals.

Recommended Temperature Ranges

Min. cold start temp / viscosity class / max. ambient temperature

  • -31F or lower – 0W-30 – 77F / 0W-40 – 86F;
  • -22F – 5W-30 – 77F / 5W-40 – 95F
  • -13F – 10W-30 – 77F / 10W-40 – 95F
  • -4F – 15W-40 – 113F
  • 5F – 20W-50 – 113F or higher

0W-40, 5W-40, and 15W-40 Difference

The main parameter of engine oil is its viscosity or fluidity. According to the classification of the Society of Automotive Engineers (SAE), the binary number in the designation of engine oils means that these oils are all-season. Most car owners usually prefer such oils because of their versatility.

The first index, e.g., 5W, characterizes oil viscosity at low temperatures. The lower the temperature, the more the oil thickens, and the harder it is to pump. The second digit indicates the high temperature of the oil. High viscosity, in this case, provides the oil film formation on friction parts of the engine.

In terms of numerical values, motor oils differ only in terms of the high-temperature viscosity index. For 5W-30, this value ranges from 9.3 to 12.6 mm2/s and for 5W-40, from 12.6 to 16.3 mm2/s.

However, we must not forget that viscosity affects the overall performance of the engine and depends very much on its design. Here again, it should be noted that when choosing the best option, you should follow the manufacturer’s instructions and use oil with the recommended viscosity and required approvals.

If your truck’s engine is designed for 5W-30, 5W-40 will increase the load on the oil pump and increase friction. This will also reduce oil consumption in the oil system, because the higher the viscosity, the higher the hydraulic resistance, which means that the operating point of the pump and system begins to operate towards lower flow rates.

This results in engine wear and oil starvation. Conversely, if you use 5W-30 instead of the manufacturer’s recommended 5W-40, the oil will be too liquid for your engine, and the film will not hold well in the piston-cylinder tribosystem, which will also cause wear.

Typically, most manufacturers recommend 5W-40 oil, as “40” is the average parameter. Oils with “30” are mainly designed for new cars, and with “50” – for vehicles with high mileage.

As a whole, the following can be distinguished for compared samples in the form of basic characteristics:

  • at average engine oil temperature, the viscosity of 5W40 is 1.5 higher than 5W-30;
  • 5W-40 is designed to operate with modern internal combustion engines characterized by their high thermal stress. This oil retains its viscosity properties well. When high shear rates and
  • temperatures are present in various areas of the engine, the oil successfully holds the film, preventing friction;
  • the temperature range of 5W-30 is shifted downwards compared to 5W-40. This means that the oil has a lower viscosity and provides a more effective result at cold starts, but at high
  • temperatures, it becomes too fluid, which almost eliminates its lubricating properties.
  • Therefore, only the manufacturer’s recommendations should be taken into account, and engine oil should be selected according to these recommendations.

0W-40 marked oil is a more practical material for a car, compared to 5W-40. 0W-40 is produced through synthesis and the most complex chemical formulas. For this reason, the content has improved formula and higher viscosity. Therefore, this lubricant does not come into harmful contact with engine parts, no oxidation processes, etc.

So, we can say that even a new ice age won’t stop you from starting the engine with 0W-40. And there is also no need to change it before summer, unless, of course, your climate is too hot. With this oil, the engine feels confident even in case of overheating. That is, if in summer (not too hot), you will use 0W-40 instead of 15W-40, the engine will not feel any difference.

Winters with lower than -4F ambient temperatures will, however, make you switch to 0W-40 anyway. Besides, few people consider 0W-40’s fuel economy benefits. Keep in mind minimum and maximum oil temperatures: -4F/113F for 15W-40 and -31F/86F for 0W-40. Consider your climate.

The main disadvantage of 0W-40 is, of course, the highest price of all motor oils on the market. For this reason, if you cannot buy 0W-40, the best choice is 5W-40 or 15W-40.

How much oil do you need? How to check the oil level and its condition?

6.0 Powerstroke holds 15 quarts of oil. So it needs almost 4 gallons of oil.

Park your vehicle on a flat surface (without any slopes or pits) and shut off the engine. Accurate measurement is only possible when the liquid is evenly distributed in the pallet.

Take a look at the manual. Most car enthusiasts have trouble checking the oil level on a cold or hot engine. Although most people recommend that you measure the engine oil level when it’s cool, otherwise, wait 15 to 20 minutes so the lubricant can flow into the crankcase – this will make it less viscous.

Not many people stumble on this step, but still. After pulling out the dipstick for the first time, you should wipe it thoroughly with a cloth that does not leave any small hairs. Next, place the stick back in, insert it fully, wait 5-10 seconds, and then pull it out again.

Now you should see the oil level. It should be somewhere in the middle of the hash marks or closer to the higher mark. If it’s higher, you are overfull.

Many people wrongly assume that the “right” engine oil level is max. or even a little higher. Wrong. Ideally, oil traces should end between the “minimum” and “maximum” hashmark, closer to the latter – that’s when you can safely close the hood.

If you’re checking the level right after an oil change, add new oil about one qt less to where you think the capacity is. Start the engine and let it idle for a minute. Shut it down, and let it chill for 5 minutes. This will make the new oil black enough to make it visible enough on the dipstick.

It would be best if you let the truck sit for a bit to ensure most of the oil is back in the pan, and you’re getting an accurate reading. After it’s rested, pull the dipstick out, wipe it off, insert it back into the tube until it’s fully seated, wait 5-10 seconds, and then pull the dipstick out and check the consistency and color of the oil fluid.

The oil that does not need changing is yellow-green. If it is dark brown or black, has a dense or watery structure, then immediately drive the vehicle to a service station or find out how to refill the engine yourself.

Following these simple rules is essential, because violating the procedure is fraught with disinformation of the driver, and thus, the untimely problem solution. If there is too much oil, it can get in the crankcase ventilation system, engine cylinders, or catalyst.

As for the lack of oil in the engine, it is a direct way to the so-called “oil starvation.” In general, both cases lead to huge risks – whether it’s expensive repairs, or replacing the entire power unit.

You have to check your engine oil level periodically. Even if the vehicle was constantly standing in the garage, there is a high probability of leaks provoked by gasket’s abrasion, seal and hose joint damage. Therefore, a proper weekly oil check will not hurt.

How often should you change your oil in Powerstroke 6.0?

As stated on powerstrokehub.com:

7,500 miles/6 months under normal operating conditions.
5,000 miles/6 months under severe duty conditions.

Powerstroke 6.0 oil temperature range. Standard reasons for high oil temperatures.

220-250 degrees. However, the perfect oil temperature for 6.0 is 200 degrees. The difference between ECT and EOT should be not more than 15 degrees (OC efficiency) at 60 mph, unloaded, on flat terrain.

The oil temperature depends on how/where you drive the truck. Extreme conditions, fast driving, bumpy roads, slopes or hills make the engine work harder, which directly affects the oil temperature.

  • The first reason for the high oil temperature is a bad oil cooler. You should check if it’s clogged or buy a new, bigger one (Motorcraft filters are good).
  • Also, check your oil pressure gauge is operating right.
  • Check if the EOT and EOC are the same. They should be.
  • You may also need a coolant filter as well.

You should monitor both the oil and coolant temps together – the one doesn’t make a lot of sense without the other.

Mobil Super 96819

Delvac 1300 15W-40 engine oil is an ultra-high performance blend for diesel engines that helps extend engine life in the harshest conditions, both on and off the road. The improved chemical composition of this oil provides high efficiency in modern high-performance engines with low emissions, including engines equipped with exhaust gas recirculation (EGR).

Older engines, powered by more moderate and higher sulfur content fuels, are also on the list.

Thanks to its properties, this oil exceeds the service category API CI-4 Plus, as well as the industrial specifications of JASO DH-1. Delvac 1300 15W-40 oil is recommended for a wide range of heavy-duty and harsh applications found in applications such as road transport, mining, construction, open-cast mining, and agriculture.

This oil will provide excellent protection for the most demanding engines (Powerstroke, Caterpillar, Cummins, Detroit Diesel, Mack, Mercedes Benz, Navistar, Volvo, etc.). Delvac 1300 15W-40 oil also meets API SL specifications for gasoline engines and mixed fleets.

The oil is the result of extensive joint development with most OEMs and the use of an improved package of chemical additives with patented Trimmer technology. These improvements ensure excellent control of oil thickening due to fouling and higher temperatures and provide superior resistance of engine parts to oxidation, corrosion, wear, and high-temperature deposits.

Modern high-performance, low-emission engines generate higher soot and run at higher temperatures than older, non-surge engines, which significantly increase the requirements for engine lubrication oils. Modern engine designs reduce oil consumption, resulting in lower costs when filling with oil to rebuild additive stocks.

Upper piston rings are located higher on the piston, bringing the lubricant layer closer to the combustion chamber, where higher temperatures increase the thermal stress on the lubricant.

Higher fuel injector pressures and slower synchronization improve exhaust emission control but also increase engine temperatures and soot coverage, including those engines that operate with exhaust gas recirculation (EGR).

Application

  • Recommended for use in high-performance diesel systems, including the latest turbocharged engines, designs with low emissions, as well as engines with exhaust gas recirculation technology (EGR).
  • On the highway, both for high speed / high load transport and for short-distance deliveries;

Liqui Moly 2050-4PK — Oil for 6.0 Powerstroke

Liqui Moly 2050-4PK

Many drivers consider fully synthetic oils to be the best. However, the concept of 100% “synthetics” is treated differently in different countries. Germany has a legally defined concept of synthetic oil. According to the German DIN standard, synthetic oil (“vollsynthetisches”) is defined as a 100% PAO base (PolyAlphaOlefins) and an additive package.

In other countries, the content of non-synthetic components in the synthetic oil base is allowed.

When you buy a real German product, you can be sure of its true quality. Buying LIQUI MOLY Synthoil you buy pure German “synthetics”.

Which Oil is Recommended for a 6.0 Powerstroke?


Obviously, it’s the one recommended by Ford which happens to be Motorcraft. However, most Powerstroke owners prefer Shell Rotella. But you should consider your manufacturer recommendations and choose what you think is more acceptable, depending on your climate, driving style, budget, and vehicle specifications.

Amsoil, Delo, Valvoline, Mobil 1, Liqui Moly are also highly popular.

How much oil pressure should a 6.0 Powerstroke have?

  • 20-25 psi hot at idle (200F oil temp);
  • 1900 rpm – 50-58 psi;
  • 58-60 psi at cruising;
  • 75+ psi at cold start.

Results may vary.

The minimum engine oil pressure specs are 82.7 kPa (12 psi) at 700 rpm, 165.5 kPa (24 psi) at 1,200 RPM and 310.3 kPa (45 psi) at 1,800 RPM with the engine at operating temperature.

In case of any deviations – check your pressure relief valve and oil pressure switch.

How to know if engine oil is diluted in 6.0 Powerstroke?

Fuel dilution occurs in any engine and it’s normal. You need to test your oil (e.g. @ polarislabs.com) and check your oil analysis report. To prevent the fuel from mixing with your oil, avoid excessive idling and make sure your fuel injector is alright.

How to change engine oil in 6.0 Powerstroke?

Make sure you have all the necessary equipment and materials before you start. You will need 15W-30 or 15W-40 engine oil, wheel chocks, a ratchet with a 36 mm socket, 3/4″ combination wrench, Motorcraft 6.0L Powerstroke oil filter with O-ring seal, drain pan, drain plug gasket, an oil funnel, newspapers, and wipes.

Before draining the oil, start the truck and leave the engine running for 1-2 minutes or go around your block to heat up the oil – this will make it easier to drain the oil. Make sure your truck is on a flat surface. Then pull the parking brake and place the chocks under the rear wheels to prevent any movements. Open the hood and disconnect the negative cable from the battery.

  • Locate the engine oil filter cover on top of the engine. Loosen the oil filter cap using the ratchet. Lift the oil filter cap to remove the filter and the O-ring attached at the bottom. Remove the filter and O-ring from the lid and dispose of both appropriately.
  • Get under the vehicle and locate the oil pan drain plug. When you find the plug, spread a newspaper and position the drain pan underneath it. Loosen the drain plug with the 36 mm socket by turning it counterclockwise. Then gently remove the plug and allow the oil to drain completely into the pan. Be careful – the motor oil can be hot. When the oil flows out (the jet will turn into separate drops), check and clean the thread of the drain plug.
  • Manually reinsert the drain plug and tighten it a quarter turn (do not overtighten or you may damage the thread and gasket) with a 3/4″ wrench. Be careful not to provoke oil leakage! If necessary, replace the drain plug gasket.
  • Replace the oil filter. Leave the pan under the machine and locate the oil filter. Loosen the oil filter with the 3/4″ wrench, turning it counterclockwise. Remove the oil filter manually. Before installing the new filter, apply some engine oil to the new gasket (check your owner’s manual) so that it does not adhere and crack. Besides, it’s also good protection against oil leaks. Finally, install and fix the new filter manually.
  • It’s time to fill the engine with new oil. Open the filler cap on the passenger side of the truck, next to the firewall. Plug the oil funnel into the socket to avoid splashing and pour 15 liters of 15W-40 into the tank when the operating temperature is over 30F, or 15W-30 if the temperature is below 30F.
  • Almost there. But you should still check the oil level. To do this, shut down the engine, take out and wipe the dipstick. Put it in and pull it out to make sure the oil level is fine.
  • Close the drain pan and remove it from under the car. Connect the negative contact cable to the battery and start the engine. Allow the engine to run for a few minutes and then check for leaks. Check the engine oil level again with an engine oil dipstick. Close the lid.
  • Pour the used oil into an old container or other suitable storage container and put the old filter in a plastic bag. Dispose of dirty newspapers and wipes. Now you and your car can both go on the road.

The best way to get rid of the old engine oil is to recycle it. Many service stations and replacement points accept old oil and oil filters free of charge.

Why do car manufacturers recommend this or that type of oil for a particular vehicle model? What are the grounds?

Based on a database for testing specific oil on their engines. No manufacturer will test all the existing oils, it makes no sense.

How justified is the use of proven high-quality oils in everyday life?

It follows from the test results that switching from a simple mineral to high-quality synthetics guarantees a 5-6% reduction of fuel consumption, reduced wear, and major repair delay, as well as an easier cold start, and an overall increase in engine reliability.

Is the use of seasonal oils (summer/winter) justified in modern conditions?

This separation makes sense for commercial vehicles with high mileage when the oil has time to work out its resource during the season and must be replaced. Moreover, frequent oil changes and large refueling volumes result in the price becoming an important saving factor.

Why, with having the API, ACEA, etc., quality systems, do we still need manufacturer’s approvals?

This is, basically, a common conflict of interests between the manufacturer (oiler) and the consumer (engine specialist). All the accepted quality systems, somehow, contain requirements for physical and chemical parameters of engine oils. And engine specialists (motorists) need the oil to work conscientiously in the engine throughout its life, from change to change.

Therefore, parameters like the level of high- and low-temperature deposits, wear protection, energy efficiency, compatibility with catalysts, oxidative stability, and tendency to sludge formation, are important for them.

It’s all strictly individual, in different motors the same oil can act differently. That’s why automobile companies test engine oils in their engines and issue approvals based on the results.

By the way, automotive companies have much tougher approval requirements than those of oil producers, which is understandable in human terms.

Will Liqui Moly Synthoil Energy 0W-40 work for me?

A Liqui Moly Synthoil Energy 0W-40 canister has a certain marking on it. If you know the markings, you will quickly decide whether or not this oil is suitable for your vehicle.
Most of the time, these markings contain all the necessary information.

Why is my oil pressure light on?

Always check your oil level. If the Low Oil Light comes on when the oil level in the engine is fine, then a faulty oil pressure sensor may be the one to blame. You need to change it. When this sensor goes bad, it will start to give false readings.

How does oil pressure regulator work?

The oil pressure regulator includes a special spring that gets compressed as the engine runs. When the oil pressure goes up, the spring is compressed harder and the oil pressure gets reduced to a more suitable level for vehicle operation.

Tips

  • Ford indicates their recommended oils on the filler cap and in the owner’s manual.
  • Go with whatever your Ford Owners Manual says for your area of the country.

If you need to compare Rotella with Motorcraft 15W-40, the latter is more expensive fully synthetic oil which you can find on Amazon. Some truck owners also claim that Supertech 15W-40 is better than non-synthetic Rotella in terms of content.
