Buying Guide

Making a choice can be a hard task. Especially when you have to consider the engine’s life. Besides, every other engine has specific requirements. And your 3.5 EcoBoost is no alternative.

Hence, you have to be aware of the features that need to be present in your purchased oil. Otherwise, your engine might suffer heavy casualties. And no one wants that to happen, now do they?

So, come with us as we go over the things that must be present in the best oil for 3.5 liter EcoBoost

The Right Oil Type:

When you will be looking for oil for your 3.5 EcoBoost you will see a lot of oils. They are all of the different types. Some are conventional. And the other ones are synthetic. While the rest are a blend of both conventional and synthetics.

But what type of oil for 3.5 EcoBoost is the best?

Well, here’s the thing. The older versions of engines could support conventional oils. But the newer version can’t. So, if you have the latest 3.5 EcoBoost engines then you should stick to either synthetic or blends.

In other words, the best oil for 2019 3.5 EcoBoost might not be the right choice for the 2014 3.5 EcoBoost. However, the only way to be sure about the right type of oil is to simply look at the recommendation for each engine.

Viscosity Levels:

Secondly, do take the viscosity into account. Each oil tends to have a different viscosity level. And the 3.5 EcoBoost engines don’t have a high requirement for viscosity.

That means low viscosity oils work with this type of engine. But we recommend you to stick from 5W-20 to 5W-30 ratings. They are proven to be the right pair for the 3.5 EcoBoost engines.

High Temperatures and Pressure resistance:

Another fundamental property of oil is its chemical stability. This determines how stable the chemical actually is when it is under intense pressure. And that is a crucial factor to consider.

This is because if the oil isn’t stable it will erupt under high pressure or temperatures. And that is something the oil will be asked to combat when it is deep inside the 3.5 EcoBoost engine.

So, do ensure that your oil can avoid wear, breakdown, and oxidation. That is pretty important.

The Presence of Additives:

Lastly, consider the presence of additives in your oil. Now, you might think that additives are bad because they don’t let the oil be in its natural state. But that is actually a misconception.

The additives are present to enhance the performance of the oil. However, they need to be present in small doses. Otherwise, they might cause more damage than good.

At the same time, it is also important to know which additives are added. Some of the additives are present for better performance while others are simply a cause of distress.

3.5 EcoBoost Oil Type by Year: Classification of Oil

best oil for 3.5 ecoboost engine

You might have heard about the 3.5 EcoBoost having different years besides their names. That indicates the year they are manufactured. And on the basis of that their oil requirements tend to change.

By that, we mean only their required viscosity level changes. But it is still important to know what your engine wants and what it can handle.

Now, we will be providing a general idea about what your engine might be suitable with. However, the best way to be sure is by looking at the cover of the oil fill cap. The oil requirements for your engine tend to be written there.

2004 to 2014 3.5 EcoBoost Engine Oil Requirements:

So, if your 3.5 EcoBoost engine is anywhere between 2004 to 2014 then you need to stick with oil that has a viscosity of 5W-20. Most of the EcoBoost works great with oil that has such viscosity level.

In fact, 5W-20 is the best oil for 2014 3.5 EcoBoost. However, if you’re buying oil for Ford F-150 with an Ecoboost 3.5L V6 engine then go for 5W-30 oil. They work best for this engine.

Latest Model of 3.5 EcoBoost Engine Oil Requirements:

On the other hand, if you own the latest model of the 3.5 EcoBoost then you should opt for oil that has a viscosity rating of 5W-30. Now, this is a bit higher than the previous ones.

This is because the latest versions of the 3.5 EcoBoost engines require heavier oil. Plus, work better with a little higher viscosity.

Thus, the latest engines require a higher viscosity. For instance, the 2019 f150 3.5 EcoBoost oil type is 5W-30.

How To Change The Oil on 3.5 EcoBoost?

After purchasing the oil you might be curious to know how to change the oil. Well, let us help you with that too. Here are some of the simple steps you need to follow:

Step 1: Prep The Car

Firstly, you need to ensure that the car is ready for the oil change. For that, take the car out on a little drive. And then turn the engines off.

Step 2: Empty the Oil

Before putting in extra oil you need to empty the existing one. To do that, you have to remove the oil fill cap and also remove the wheel dipstick. Most of the oil will flow out on its own.

Step 3: Insert A New Oil Filter

Once the oil is drained, lift the front side of the vehicle. For that, use a vehicle jack or ramps. Then go under the car and remove the lock from the underbody shield.

Later on, take the underbody shield off. After that, set the oil drain pan under the filer and use a ratchet to rotate the filter. But be careful because the oil will be hot.

After the filter is removed the remaining oil will drain out. Then you can take off the gasket and clean the surface. Later on, you can insert a new filter

Step 4: Fill Oil Into The Tank

Next, you need to put the oil drain under the oil pan and remove the oil pan cap. To do this use a ratchet. After that, empty the oil pan and clean the surface.

Next, insert the cap and rotate it using your hand. Then attach the underbody shield and lift up the truck. Once that’s done refill the oil and put the oil fill cap back on.

Step 5: Start The Engine again

Lastly, start the engine again. This will ensure that the oil flows properly within the engine.

Any More Questions?

How much oil should I use for EcoBoost 3.5 engines?

Most of the EcoBoost 3.5 requires 6 quarts of oil. However, others require 5.67 liters of oil. That is close but you might get a spill if you tend to go overboard.

What happens if I use oil with low viscosity on 3.5 EcoBoost?

The 3.5 EcoBoost needs a low viscosity oil. But using one might cause the oil to vaporize faster under high temperatures.

How often should you change the oil in 3.5 EcoBoost?

Oil for EcoBoost 3.5 engines needs to be changed every 30,00 miles. Otherwise, you will run out of oil.

Should I be worried about my 3.5 EcoBoost being hard on oil?

The EcoBoost 3.5 engines do tend to put the oil under a lot of stress. That is why it is recommended for drivers to not push past the maximum oil change interval.

Final Verdict

Well, that sums up our guide for the best oil for 3.5 EcoBoost. By now, we hope you have found the right oil to go with your version of the engine. But if you are still confused then we suggest your stick to our top pick.

It is the number one product for a reason. So, do go with our judgment and we promise you won’t regret it. Anyway, we have rambled on for ages. It is time to say goodbye. Take care and adios!
