How to Choose A Oil for 3.5 Ecoboost

We have already enlisted what we considered as the best oil for Ecoboost 3.5. But still, you must be wondering how we came to that conclusion, right? Once you read out the choosing factors, things will be more apparent to you.  Even if you want to go for a different oil than these, you’ll know what you are looking for. So, let’s not waste time!

How to Choose A Oil for 3.5 Ecoboost

Synthetic oil is a must!

Since the 1990s, Ford has put forward using synthetic 5W-20 or 5W-30 in the engines. When it comes to the 3.5 L Ecoboost, Ford recommends the 5W-20, but 5W-30 also works just fine. Now, the question is why?

Synthetic oil is preferably purified, distilled, and broken into essential molecules rather than refined from crude oil like typical motor oil. It allows creating uniform hydrocarbon molecules. And guess what that results in? Oxidation stability, resistance to thermal breakdown, better wear protection, and so on. And ultimately, your engine performs better and smoother, with improved gas mileage, hence, some right role to play in the fuel economy too!

But is the synthetic oil compatible with different engines? Yes, 100%

I agree that the price is relatively higher than the conventional motor oil, but imagine the extended service intervals! You won’t need to change your engine oil for 15,000 miles or even more, worth it!

Overheating protection

Considering Ecoboost engines, that’s one refined engine with swift gears. And so metal-to-metal contact is quite an issue these engines have to face. You cannot always drive your masterpiece car smoothly or slowly, and whenever there’s a bit of roughness or fastness, you don’t want your engine gears to wear out because of increased friction. 

The more the friction between the parts, the more heated the engine is. It may ultimately result in persisting engine damage, which I’m sure you don’t want. Hence, it would help if you went for an option with a higher viscosity index and lubricate all the engine parts equally. So even if that five qt. A bottle costs you a few more bucks; you should sign up for it!

Weather compatibility 

You don’t always get to have a sunny day when taking your car for a ride. Especially in the winters, it’s one heck of a problem for your car engines. The cold start-ups, the difficulties in starting the car, and of course the increased engine deposits! 

To handle all such problems, you must make sure your engine oil works fine no matter the weather conditions. If your motor oil can resist both low-temperature gelling and high-temperature oxidation, then you can roam around the world without worries! 

I must say that all the enlisted motor oils give a tough fight even in the harshest weather conditions, only to keep your engine going. Also, don’t forget to check if your synthetic oil can help reduce engine deposits. In this case, the enlisted Mobil 1 5W-30 works like magic!

Extra pressure handling 

If we look at today’s engines, the pressure these engines need to handle has double in the last few decades due to increased performance demand. You will be surprised to know that the pressure can even reach up to 10 tons per square inch underneath the hood, which is like five car pressures relying only on a thin layer of oil for protection! Hence, there cannot be an alternative to more robust and advanced oil technology. 

If the pressure is your concern, I’d suggest the Castrol 03083 Edge with fluid titanium technology to combat the increasing engine pressures. It changes the physical behavior of your engine oil. And with more significant pressure, you get more strength. Nothing less than a miracle, huh? Not really; it’s just advanced technology.

Greater mileage

Yes, we all sometimes forget to change the oil timely, and if the interval is less than 5000 miles, it’s merely frustrating to change the oil frequently.  If you look at our chosen products, they can last for more than 10,000 miles, which is more than enough.

Well, let me clear the confusion. If you still think those extra bucks might be too hard on you, think about the long road trips where you forgot to change your oil and now are stuck in the middle of nowhere!

Reduced friction

With the synthetic slippery medium between your engine gears, the metal contact reduces, and so does the friction.

Of course, you want your engine to last as long as possible. But with the regular rough driving, loads of friction can cut half of your engine life. The only armor that can save your engine would be good motor oil. Hence, no matter which synthetic oil you have in mind, make sure it reduces friction and protects against frequent wear and tears. Voila! Ultimately you get a longer life span for your engine and help in the total fuel economy. That’s a real win-win.

Don’t forget your budget!

If you have made up your mind to use some of these synthetic oils in your engines, then what’s stopping you? The price, of course. 

Yes, I agree that conventional motor oil is much cheaper than these synthetic oils but have you wondered what they do to your car engine? The quick wear and untimely engine damage are not worth the few bucks you are trying to save. So, this isn’t even a question anymore!


Do Ecoboost engines require synthetic oil?

Ecoboost, but almost all the high power and performance turbo engines need synthetic oil; semi-synthetic is fine. For Ford F150, you must check out the guidelines before you get the engine oil.

What kind of oil does a 3.5 Ecoboost take?

According to Ford recommendations, your 3.5 Ecoboost needs API SM certified 5W-20 or 5W-30 motor oils.

How much horsepower can you get out of a 3.5 Ecoboost?

Well, a smooth 400 hp or even more!

Final Verdict 

For me, my car engine’s lifespan is worth more than the few extra dollar savings. And so I really needed something that would make sure I have functional car engines. Certainly, relying on the enlisted synthetic oils didn’t do me bad, rather I can travel around with my Ford without absolutely no worries!

If you have been going through the review thoroughly, then you shouldn’t be in any further dilemma as to what can be an ideal match for your 3.5 Ecoboost. So, my advice, without further damaging your precious car engines, get the best oils for your 3.5 Ecoboost right away!
