Does the 2.7 EcoBoost require premium fuel?

In this blog post, we will answer the question: “Does the 2.7 EcoBoost require premium fuel” We will talk about the 2.7 EcoBoost key features and its specifications. We will also talk about the 2.7 EcoBoost maintenance schedule. At the end of this post, you will get to know about the 2.7 EcoBoost and its unique capability.

Does the 2.7 EcoBoost require premium fuel?

No, the 2.7 EcoBoost does not require premium fuel. The 2.7 EcoBoost requires 87 octane fuel to run without any issues. The 2.7 is one of those fuel-efficient engines and is one of the best engines for the Ford F—150 series. The 2.7 EcoBoost does not need premium fuel to reach its full potential. This engine is built to run on lower octane fuel.

Although the 2.7 EcoBoost is a fuel-efficient engine, it is recommended not to go below 87 octane fuel. On the other hand, the owner’s manual recommends running premium fuel when towing. You can also use 91 and 93 octane and run the engine successfully without any hassle. Just make sure not to go below 87 octane fuel and try to use premium while towing.

2.7 EcoBoost key features

The 2.7 EcoBoost is no doubt one of the best engines for the Ford F-150 series. It has incredible power and it can easily tow vehicles with a torque of 375 lb-ft and a horsepower of 325. The 2.7 EcoBoost is a twin-turbo engine that is built with compact graphite iron, which is usually used for 6.7 power stroke diesel engines.

Single iron casting upper block

  • The 2.7 EcoBoost has a single iron casting used for the upper block. The engine consists of a two-piece block and only the lower half is made from aluminum.
  • The upper block includes the cylinders and the main bearing caps. These caps have a three-dimensional mating surface to produce extra stability. Ford has successfully tested engines without the caps bolted.

Die-cast aluminum lower block

  • The lower black is made up of die-cast aluminum. Ford broke out from the typical single material engine block and they managed to save weight with the aluminum die-cast. 
  • The aluminum lower back bolts onto the iron upper half. There are a second set of blots that secure the bearing caps to keep the engine stiff.

Double-end piston rods

  • The piston rods have double ends in the 2.7 EcoBoost. The big end is connected to the crankshaft and the smaller end is connected to the piston itself. 
  • These piston rods have a highly durable coating for better distribution of oil. This also helps reduce the engine’s overall height and helps to keep it compact and powerful at the same time.

Sturdy piston-ring seats

The piston-ring seats are sturdy with a steel insert in each aluminum piston. This was developed for the top oil ring to improve durability. The 2.7 uses a tactic that is often seen in Formula One. With tiny holes in the lowest ring seat, it oil can escape to the crankcase. Hence, it reduces the drag from oil buildup when the vehicle is moving at high speeds.

The 2.7 has several features that make this engine a class-apart. It also has fractured main bearing caps and a topside engine-mounted cartridge. This engine is easy to service with such features and no doubt it is compatible with the regular 87-octane gasoline. These are the unique features of the 2.7 EcoBoost listed below.

  • Individual piston cooling jets
  • Offset I-beam connecting rods
  • Aluminum cylinder heads with water-cooled exhaust manifolds
  • Composite intake manifold
  • Variable intake and exhaust camshaft timing
  • Standard automatic start-up technology
  • Quick start-up when the accelerator is depressed
  • CGI engine block
  • Direct injection to eliminate the risk of detonation.

The 2.7 engine is one of those reliable engines and it can last long. These engines are built for rough handling and strong towing capabilities. The 2.7 EcoBoost can easily last around 200 thousand to 230 thousand miles. However, like all other engines, you will be required to maintain the 2.7 EcoBoost.

2.7 EcoBoost specifications

The specifications for the 2.7 EcoBoost are incredible and they are also available in various trim levels. These are some of the key specifications of the 2.7 EcoBoost.

  • Horsepower – 325
  • Max Torque – 400 lb. –ft.
  • Estimated Fuel Economy – 20 miles per gallon in cities and 26 miles per gallon on highways
  • Max towing capacity – 10,100 pounds
  • Max payload capacity – 2,480 pounds.
  • 10-speed automatic transmission

The 2.7 EcoBoost is no doubt a powerful and successful engine that has been available since 2015. These engines turned out to be a huge success as soon as they hit the market. Yet, the 2.7 EcoBoost needs to be maintained consistently to last longer and more efficiently. Regular maintenance is the key to a long-lasting engine.

2.7 EcoBoost maintenance schedule

With the 2.7 EcoBoost maintenance, you will be required to follow a particular schedule to maintain your engine regularly. Here’s how often you need to service the 2.7 EcoBoost according to the maintenance schedule.

Replace the engine air filter

  • The engine air filter must be replaced every 30,000 miles or as required. In case you encounter any problem with the air filter, be sure to replace it immediately.

Replace the engine oil

  • The oil for the 2.7 EcoBoost must be replaced every 10,000 miles or one year, whichever comes first. In some situations, you will be required to replace the engine oil every 7,500 miles, especially if there is wear and tear on the engine.

Change the accessory drive belt

  • The accessory drive belt must be replaced every 150,000 miles. It is also recommended to inspect the drive belt frequently and replace it if necessary.

Replace the engine spark plugs

  • The engine spark plugs need to be maintained and replaced every 100,000 miles. If there is excess wear and tear on the engine, you are required to change the engine spark plugs every 60,000 miles.

Change the transmission fluid and filter

  • The transmission fluid and the filter must be changed every 150,000 miles. This also helps the engine to run smoothly.

Replace the engine coolant

  • The engine coolant must be replaced every 100,000 miles or every six years, whichever comes first. You might be required to change the coolant every three years if needed.

Replace the rear axle fluid

  • The rear axle fluid must be replaced every 150,000 miles as it is equally important just like the other accessories.

Replace the transfer case fluid

  • The transfer case fluid must be replaced every 60,000 miles in case of heavy usage. With moderate usage, you can replace the transfer case fluid every 150,000 miles.
  • The 2.7 EcoBoost needs proper maintenance just like all the other engines. The 2.7 EcoBoost has twin parallel mounted turbochargers and these turbochargers provide enough horsepower and torque. 
  • This powerful engine has strong towing capabilities and it can easily tow lightweight travel trailers and caravans.

The 2.7 EcoBoost is perfectly adaptable with 87 octane fuel and it can also be used with 90 and 93 octanes. The 2.7 EcoBoost has an excellent balance of performance, power, and towing. Ensure to get your vehicle serviced often to last longer. The 2.7 EcoBoost is a durable engine but you must be required to change all the fluids and oils from time to time.

The 2.7 has a faster turbo spool and improved turbo efficiency. The increased airflow and small MPG improvements have made the 2.7 EcoBoost a class apart. This is one of the most successful engines from Ford for the F-150 and there have been no major complaints as such with the 2.7 EcoBoost.
