Taking the first spot easily is the 03083 Motor Oil by Castrol. The brand has been continuously taking up the top spots on my articles.

This is because their oil products ranging from the Edge to the Magnatec to the GTX have been engineered with one aim in mind, to provide the best user experience possible.

Well, Castrol delivers on that aim every single time. This Edge product is fully synthetic motor oil.

Unlike conventional oils, this one has been designed from the ground up to withstand all sorts of conditions. It can work under extreme loads and can also work at extreme temperatures.

If the environment gets too hot, you won’t ever have to worry about the oil having a breakdown.

In cold conditions, the low viscosity of the oil allows it to flow easily, hence avoiding startup problems.

For the engine to last as long as the rated amount, you need to take special care. Driving the truck without maintaining it will only cause the engine to degrade faster.

One of the major steps you can take is choosing the right type of oil. This one reduces metal on metal contact at all speeds.

This reduces wear on the engine considerably, allowing it to work for a longer period. The main problem with modern-day engines is the formation of deposits.

These deposits form in the pipelines, and they affect the flow of oil. This then reduces the horsepower production.

Well, you won’t have to worry about that anymore with this Castrol Edge product. It is like the brand knew exactly what people wanted and dialed it up a notch.

With 13000 ratings, there are bound to be some unhappy buyers.

Some unhappy users reported that after using this product, their vehicles started to perform poorly. Others stated that the oil causes knocking issues in the engine.

  • Reduced metal on metal contact
  • Reduced chance of deposit formation
  • Can work in extreme temperatures
  • Fully synthetic
  • May cause performance issues
  • Knocking issue

Although Castrol has created an astounding product that deserves the top spot in this article, they need to look into those performance issues that people brought up.

Other than that, the most probable chance is that you will be more than satisfied with this one’s performance.

It is the consensus that fully synthetic oil is better than a synthetic blend. This is not always true.

For example, this motor oil by the Brand Motorcraft is a blend and is way better than some of the other fully synthetic offerings by different brands on the market.

Another thing about this one that will attract all sorts of buyers is that Ford recommends it.

Who knows better about the ins and outs of the engine than the manufacturer itself?

If they advise users to use this product with their engine, then surely there must be something different about it.

The oil uses specially designed in-house additives that allow the engine to work full capacity without ever having to worry about deposits.

As stated with the previous product, deposits directly impact the engine’s ability to produce horsepower.

This one prevents that. It is also great at reducing wear on the engine. It does that using several methods.

First of all, it reduces friction in the engine. Friction creates additional load on the engine, and it has to work harder to produce the required horsepower.

Reducing that lessens the load on the engine, which can then work efficiently. You also get better fuel consumption by this.

Moreover, the chance of rusting is also reduced, which shortens the engine’s lifespan and contaminates the oil. Contaminated oil is not that effective as a clean one.

So, by reducing the chance of rusting, you can kill two birds with one stone. Being a blend, this oil has some pretty remarkable features.

As expected with a Ford recommended product, you don’t experience any issues with this one.

Buyers were happy with its performance, and judging by their ratings, they would buy it again.

  • Reduces friction
  • In house additives for controlling deposit formation
  • Reduced chance of oxidation
  • Longer engine life
  • None

This product had close to 300 ratings. I understand that people don’t buy it because it’s not fully synthetic, but Ford still recommends it.

The Castrol Edge is superior to it, but you can’t go wrong with this one either.

3. Havoline 5W-30 High Mileage Synthetic Blend Oil

Wow! Here comes another blend of oil. It looks like Ford truck owners have a different way of thinking.

Never have I ever come across two synthetic blend oils which made their way onto my lists.

Well, they do put up a pretty decent competition. Havoline is another popular brand that is regarded by people all around the world.

Their offerings are decent, but they never were able to make their way on one of my articles until now.

This 5W-30 High Mileage Synthetic Blend Oil is quite popular with Ford truck owners.

This one has been formulated for engines that have been used for long periods. It reverses the state of your engine, which is a feature not commonly found in other oils.

The Deposit Shield Technology eliminates already formed deposits and minimizes oil leaks.

These oil leaks may become visible when the deposits are broken. The oil repairs them, too, making sure optimum oil pressure is maintained.

The rust protection of this oil is also top-notch. As a result, you don’t have to worry about the engine giving in quicker than it needs to be.

The brand has also used cleansing agents that clean the engine from the inside. The reduction of contaminants means that the engine will work efficiently.

These contaminants also affect the performance of the oil, which also has to be changed quickly. The oil also meets all requirements for high-end oil.

If you are hesitant to buy it due to this, then you don’t need to worry.

Although most buyers were satisfied with this one’s performance, some complained that this product is not synthetic.

This is strange because this completely goes in the opposite direction of what the brand claims about this product.

  • Seals oil leaks
  • Destroys and prevents deposit formation
  • Cleansing agents to reduce contaminants
  • Meets all requirements
  • Wrong product delivered

Although this one is great, the only probable reason for users complaining about the oil being not synthetic is that they received the wrong product.

In that case, the brand needs to double-check what they are sending to the buyers.

4. Valvoline Advanced Full Synthetic Motor Oil

We are coming close to the end here, and the competition is quite tough. Arriving in fourth place is a product by Valvoline, another brand that has repeatedly dominated my list.

With over 11000 ratings, this oil should be the one you should go for if you rely on user experience. This one has been engineered for trucks that are used for extensive periods.

The main problem with oils that are used in vehicles like this is they break down easily. This Valvoline oil is resistant to that.

As a result, you can overwork your vehicle all you want; you don’t have to worry about the oil not keeping up.

This product uses the brands in house additives that improve engine health. These additives reduced wear by more than 40% of the industry standard. That is seriously impressive!

The company went out of its way to provide users with the great experience possible. Talking about safety, this one also protects the engine from deposit formation.

You must be noticing that I stress on this quite a lot. The reason is that deposits pose a risk to the engine.

They can cause leaks and reduce drain intervals. You don’t have to worry about that anymore. The oil is also API SP certified.

This means that it checks all requirements needed for an oil to be good for everyday use. Whether it be rusting or wear, this product will provide you with top-notch protection.

Buyers were upset because they received leaking bottles. Now, the manufacturer would never send bottles that were damaged.

So, the blame falls upon shipping. They should be protected more so they don’t rupture during transit.

  • Reduced deposit formation
  • Can work in extreme temperature conditions
  • API SP certified
  • Less chance of rusting
  • Leaking bottles

Although the chance of receiving bottles that are leaking is relatively low, it is still possible.

Regardless, the product itself is excellent and will surely satisfy you, given that you receive it in one piece.

Would you look at that! Ending the article is another product from the Brand Castrol, which already stole the top spot on this article.

The 06440 oil is a high mileage motor oil, much like the Havoline one. It has been manufactured for trucks that have been used for quite some time.

Aimed to reverse the state of an engine, this high mileage motor oil makes sure your engine is in good shape. The GTX oil has less phosphorus than other competing oils.

This has been replaced by their patented technology that reduces emissions and retains engine performance like never before.

Being a 5W-30 oil, it is perfect for use in all sorts of temperature conditions. I mentioned phosphorus a few lines back.

Although this element effectively improves the engine’s performance, it produces extremely poisonous emissions via the catalytic converter.

The brand has eliminated that use and created a more eco-friendly product. I don’t know about you, but I would feel good to contribute less to pollution.

And, this oil is also synthetic blend motor oil. It looks like companies upped their game when it comes to Ford trucks with their synthetic blend oils.

The blend consists of oils and antioxidants, and detergents, which help fight to increase an engine’s life.

The antioxidants help in controlling rust which is an ever-growing problem in vehicle engines.

It contaminates the oil and compromises the integrity of the engine, reducing its lifespan severely. But, you don’t have to worry about that anymore.

Buyers complained that their package was either opened before or was leaking on arrival. That is surprising because the first Castrol product had no issues like that.

This is to be blamed on their shipping methods. It looks like the package one lines up more carefully than the other.
  • No phosphorus used
  • Reduced emissions
  • Controls oxidation
  • Patented technology
  • Opened bottles
  • Leaking package

Castrol needs to look into why this product has shipping issues. However, if you do receive a complete package, then you will certainly be satisfied with the oil’s performance.

Frequently Asked Questions

Q1. What Oil Does Ford Recommend For The 3.5 EcoBoost?

Brands’ recommendations change as oil quality gets better. For example, Ford recommended the 5W-30 for their engines till 2002.

After that, they shifted to recommending the 5W-20 for all the engines, including the EcoBoost. Now, this does not mean that the previous one is incompatible.

Instead, the company regards one oil over the other because of its compatibility with their engine.

As to which brand you should go for, as I recommended in conclusion, Castrol oil is the best one for your engine.

Even though it is a 5W-30 oil, it works better than the Motorcraft one, recommended by Ford itself.

Both of them have excellent performance, but you should only go for the second one if you want to play safe or if the Castrol one is not available in the market.

Q2. Does Ford Recommend Synthetic Oil?

This is a question that I had to research properly to get a solid answer. Although synthetic oil is better, Ford recommends blends due to their better performance in some areas.

For example, blends have less volatility, meaning you get an extended drain interval. Blends also normally work better in high temperatures when comparing to the alternatives.

But Ford does not consider the latest and greatest product offerings from brands like Valvoline and Castrol. Their synthetics work just as well, if not better.

Q3. How Often Should I Change The Oil In The 3.5 EcoBoost?

Each oil manufacturer recommends its mileage for its product. But the truth is they have not tested in all supported vehicles. So it would be great if you played it safe in this regard.

I will be mentioning the oil replacement and other important components replacement mileage, so you don’t have any issues.

The oil should be replaced every 5000 miles if it is a synthetic blend. This ensures your engine gets a fresh product that is fully effective every few months or so.

However, if you use fully synthetic oil, then I would recommend that you change the oil every 7500 miles. The oil filter should be replaced every 3000 miles.

This is an extremely important task because the filter filters all contaminants from the oil, making sure it works at full effectiveness.

The engine also remains clean. These contaminants can cause leaks or other issues, which are then expensive to repair.

So, it is recommended to change the filter twice a year or every 3000 miles, so your engine stays in a healthy shape.
