1. Shell Rotella T5 Synthetic Blend Motor Oil
Now I know you must be thinking that the first product on this list is a blend, while it is clear that fully synthetic alternatives are better.
That is true. But in the case of the 7.3 Powerstroke, this Synthetic Blend Motor Oil by Shell defeated the competition. This is a close to impossible feat, but the brand achieved it.
The first thing the brand mentions about this product is its reduced emissions.
Thanks to the low ash formulation of this one, the exhaust does not have to produce that many toxic gases as before.
This means that the vehicle will release less harmful exhaust gases. This also ensures that the vehicle will comply with all emission rules and regulations.
Being blended oil, it has two parts, conventional and synthetic. Most of the wonders are done using synthetic components.
These components allow the engine to start in cold weather easily. No more cold starting issues for any of you readers who live in low temperatures.
The manufacturer also guarantees a clean engine throughout the usage of this product. It has been engineered to keep the engine in pristine condition.
You won’t have to worry about deposits and component failure with this one flowing through your engine’s pipelines.
Although the chance of this happening is slim to none, Shell still needs to look into this matter to ensure future buyers won’t face this issue.
- Low emissions
- Perfect for cold weather
- Excellent engine cleanliness
- Deposit protection
- Leaking package
This oil by Shell is great. It has been highly rated by more than 1000 people.
Being a synthetic blend oil, it is better than hundreds of fully synthetic options on the market. Now that is something.
2. Ford Motorcraft Super Duty Oil
Taking the second spot on this article is a product from Ford itself. Now, who wouldn’t know how to design an oil better than the engine’s manufacturer itself.
Plus, this Motorcraft oil has been designed specifically for Powerstroke engines. This means that there should be no doubt about compatibility issues.
The company takes pride in its use of premium base oils, which, when combines with their additive technology, allow it to give you excellent performance.
This one is a conventional oil that, again, may receive criticism from some of you.
Conventional oils have rarely entered my list, leave alone scoring a high place. But Ford was able to do it.
This product is designed to maximize your engine life. It will protect it from all major issues. One of the major problems that occur with high mileage engines is the formation of deposits.
These deposits form in the pipelines, which prevent the oil from reaching the engine at full pressure.
You may notice that when the engine starts to produce lesser horsepower and has reduced performance, in general.
Moreover, this Motorcraft product also protects the engine from rust. As most of you know, rust is a common issue with engines.
It not only compromises its durability and shortens the lifespan; it also contaminates the oil. Well, you won’t have to worry about this anymore.
They received some before and some after, with a few weeks gap within. I don’t know why they do this, but they need to sort it out.
- Made by Ford
- Premium base oils
- Maximizes engine life
- Reduced chance of deposit formation
- Bottles shipped separately
Even if you are a victim of this poor shipping method, you still have the guarantee that the order will be delivered in a proper fashion.
The product itself is great and will surely exceed your expectations.
3. Valvoline Premium Blue SAE Diesel Engine Oil
You are in for a treat with the third product on this list. This Diesel Engine Oil is Made by Valvoline.
They have been making premium quality oils for years, and their products wind up on my articles almost every single time.
This Premium Blue oil is proof of their expertise in manufacturing high-quality products.
This one aims to provide you with both performance and protection from one oil change. It has some pretty unique offerings which will be appreciated by you and your engine.
The first thing that you should know is that the oil will reduce emissions significantly. This applies to all diesel engines, regardless of the technology.
Whether the engine has EGR technology or has DPF, you will notice reduced emissions.
I don’t know about you, but I would certainly feel good if I would have less contribution to air pollution.
Furthermore, the brand promises that the drain interval for your engine will be 10000-miles.
That is a lot! And if you convert these numbers, you can expect an oil change to last around one year. The oil also protects the engine from rusting.
You won’t have to worry about the engine having a short life due to oxidation. Rusting also contaminates the oil, which shortens the drain interval.
By controlling that, you are able to get the extended drain interval I talked about a few lines back.
If you are looking to play safe and buy a product that is fault-free, then this Valvoline oil is best suited for you.
- Reduced emissions
- Up to 10000-miles drain interval
- Reduced chance of rusting
- Works with all sorts of diesel engines
- None
Valvoline has made a great product that checks all the boxes to keep the 7.3 Powerstroke in excellent condition. You will be more than happy with this oil.
4. Royal Purple 44154 High-Performance Synthetic Motor Oil
Finally, coming in fourth place is the synthetic oil. Now, I know that many of you must be wondering that how come synthetic oil was not able to take a spot on the first three positions.
The thing is, the brands that earned their respective positions create absolutely outstanding products which beat other synthetics on the market.
Royal Purple is a highly regarded brand that has been making quality products for quite some time now.
Their oil products are designed to optimize the engine to ensure long life and better performance. It is rare to see improvements in fuel efficiency just by changing the oil.
Well, this Royal Purple High-Performance Synthetic Motor Oil makes that difference. It should be noted that the improvement in fuel-saving may not be noticeable.
But it certainly is there. The catalytic converter of a vehicle transforms harmful gases into carbon dioxide and water vapor.
Although it is effective, the converter is not able to convert all of the gases. You won’t have to worry about that because this one automatically reduces emissions.
Lesser emissions mean a reduced impact from your side on the environment. The oil also provides you with better wear protection, extending your engine’s life.
The most probable reason must be that he might have received a faulty product or one that has been on the shelf for too long.
- Better wear protection
- Better fuel efficiency
- Reduced emissions
- Reduced fuel efficiency
The chance of you getting low fuel efficiency is close to zero. But it is still possible. Regardless, the product is an excellent one and surely deserves a spot on this article.
5. Mobil 1 Super 96819 15W-40 Motor Oil
Taking the fifth spot is a product from another highly popular brand Mobil 1. There are regarded worldwide for their high-quality oil products.
The 96819 Delvac Super Motor Oil is yet another synthetic blend oil. It looks like brands really did all they could to make their non-synthetic lineup work flawlessly for the 7.3 Powerstroke.
One of the first things the brand mentions is that this one meets or exceeds OEM specs.
What this means is you are getting a product that surpasses or meets all requirements, making it more than capable of handling your vehicle’s needs.
Designed for all sorts of engines in mind, this is suitable for use in older or new engines, regardless of the mileage.
It will work in a manner that will satisfy you, no matter the application, whether on-road or off-road.
The company boasts its extended drain intervals. This oil can work with full effect for 7500 miles for the 7.3 Powerstroke and 1.5x of any diesel engine’s recommended interval period.
Now that is impressive. This is mainly possible due to the excellent oxidation and viscosity control provided by this product.
It even provides you with 50 times more wear resistance than industry standards. The brand has stepped out of its way to ensure you are getting as much protection as possible.
You can worry less about the oil getting any issues and drive with complete peace of mind.
This may be a source of frustration if buyers don’t know what to expect. The company really needs to solve these shipping issues.
- Meets or exceeds OEM specifications
- 1.5x longer drain interval
- Reduced chance of rusting
- 50% better wear protection
- Order shipped in parts
If Mobil 1 does not cause issues such as sending an order in a divided fashion, the buy is perfect for all 7.3 Powerstroke engine owners.
6. Lucas Oil 10299 15W-40 Synthetic Motor Oil
I am going to be honest with you. This is the first time I am hearing the name Lucas Oil. But, what I know is this brand will certainly not leave my mind.
The manufacturer has created a pretty fantastic product which not only impressed me but was also highly liked by buyers.
Designed specifically for heavy-duty engines such as the 7.3 Powerstroke, this 10299 15W-40 Synthetic Motor Oil allows the engine to work more efficiently.
You can expect better emissions while maintaining a slow pace of oil consumption. Better emission means less production of harmful gases.
This product, yet again, is another one that claims to meet or exceed industry standards.
What this means, in a nutshell, is that the brand has gone above and beyond to ensure you are getting the maximum performance from your engine while keeping it safe.
The product also provides you with all the goodies you would expect from decent oil.
You get better rust protection to ensure the engine is not compromised and the oil remains contaminant-free.
There is one claim by the brand which makes it seem a little bit suspicious. They say that they have tested their oil for up to 30000 miles, and it was still good to use.
Such a drain interval is unheard of, but if it is true, then it truly is a game-changer.
- Meets or exceeds industry standards
- Protection from rust
- Better emissions
- Long drain interval
- Fewer ratings
If you are one to take a risk and want to order this one, then I would request you to leave a rating online, so future buyers know what they are getting.
7. AmazonBasics Full Synthetic Motor Oil
Finally, taking the seventh and final place is a product by AmazonBasics.
This product has the highest number of ratings, crossing 18000. Well, when Amazon makes a product, they make sure to impress buyers.
This oil is designed for those truck owners who live in the cold. For exceedingly low temperatures, you need oil that is equipped to handle them.
Well, thin and light 5W-40 oil is hard to beat in this category. Thanks to its low viscosity, it flows easily, which is the requirement of engines working in cold environments.
Although the brand did not mention the exact number, they state that this one allows users to have an extended drain interval.
This means that you will have to worry less about changing the oil and can focus more on driving.
The oil also reduces friction. Friction is one of the main reasons for wear on a vehicle’s engine. The engine also has to work hard to counteract its effects.
This reduces fuel efficiency. So, by reducing friction, you might see an improvement in fuel consumption. Bear in mind that the difference may not be noticeable.
Moreover, the oil also reduces exhaust emissions. You will contribute less to air pollution. There is a certain peace of mind knowing that.
The oil also works in extreme temperatures with ease. It will resist breakdown at high temperatures, which is a common problem with oil products on the market.
This means that either the product is not widely compatible, or there must be a bad batch that was sent out to users.
- Suitable for extreme temperatures
- Low viscosity
- Better fuel efficiency
- Reduced friction
- May impact performance
Although Amazon has created a great product that was loved by more than 18000 people, they must still look into the performance issues reported by other buyers.
