What To Look For While Buying Oil For 3.5 Ecoboost?

What To Look For While Buying Oil For 3.5 Ecoboost

Motor oils improve engine efficiency and minimize the wear to prolong the engine’s life. Different factors like viscosity index, ability to form in various temperatures, mileage, and composition make oil perfect for specific engines in specific conditions. If you are curious about what makes an oil best for 3.5 Ecoboost, give a read to this buying guide.

Mileage Or Change Interval

Mileage and Change interval decide how frequently you need to change the motor oil. Quality motor oil offers a higher mileage and maintains the engine’s efficiency till the end of a change interval. Full synthetic oils have higher mileage than blend oils.

Blend oils have mileage between 3000-5000 miles or a change interval between 4-5 months (whatever comes first). On the other hand, full synthetic oil with its advanced formula and outstanding thermal and oxidation stability offer a mileage between 8000-10000 miles for a 3.5 Ecoboost engine.


Seasonality is another critical factor, and you must consider the weather and temperature conditions of the area before buying new motor oil. 5W-30 is a multi-grade oil that performs well in all seasons and eliminates the need to change oil with every changing season.

With higher thermal and oxidation stability, this oil performs well even in extreme temperatures. This factor is critical for people living in cold climates since there are frequent cold start issues. High-temperature resistance keeps oil active and offers an easy startup.

Gear Shifting

Motor oils minimize the friction between mechanical parts and help them slide past each other. This factor depends on the oil viscosity index. Remember, every engine has a different viscosity index requirement. According to Ford 5W-30 and 5W-20, both are compatible with 3.5 Ecoboost.

However, according to the user’s experience, the viscosity index of 5W-30 is found to be ideal for 3.5 Ecoboost. The higher viscosity index improves the engine’s friction performance under higher stress and ensures smooth and seamless gear shifting.

Deposit Clogging

Deposits are among the engine’s biggest enemies. Deposits and sludges can clog the engine valves and slow down the engine performance. Therefore motor oil uses detergents to minimize the formation of deposits in valves.

You must opt for motor oil containing active detergents like calcium and magnesium to reduce deposit formation and engine clogging. Detergents maintain optimal performance and also prolong the engine’s life.

CO2 Emission

Cos2 emission should also be your concern as a responsible citizen. Low viscosity oils such as 5w-30 and 5W-20 are highly compatible with 3.5 Ecoboost and significantly improve the combustion process. You can minimize the CO2 reduction by using a fully compatible, high-quality motor oil.

Ease Of Handling And Packaging

Safe handling and convenient packaging are essential things related to motor oil. Entirely synthetic oils are highly non-bio-degradable, and there you need to be careful while changing the oil. You must look for a safe and convenient package to minimize the chances of leakage and oil spills.
