Hey guys! If you're the proud owner of a 2018 Ford F-150 with the 3.5L engine, you're probably wondering about the correct oil capacity for your truck. Knowing this crucial detail ensures your engine runs smoothly and stays healthy for years to come. Let's dive into everything you need to know about the oil capacity, recommended oil types, and essential maintenance tips for your 2018 F-150 3.5L. Let's get started!

Understanding the 2018 Ford F-150 3.5L Oil Capacity

So, what's the magic number when it comes to the oil capacity for your 2018 Ford F-150 with the 3.5L EcoBoost engine? The standard oil capacity is 6.0 quarts (5.7 liters). It's super important to stick to this amount to ensure optimal engine performance and longevity. Overfilling or underfilling can lead to serious engine issues, so precision is key! Always double-check your owner's manual to confirm this specification, as slight variations can occur based on specific engine configurations or model updates. Using the correct amount of oil ensures proper lubrication, cooling, and cleaning of engine components, which are vital for maintaining its efficiency and preventing wear and tear.

When you're adding oil, make sure to use a reliable measuring container. Slowly pour in the oil, periodically checking the dipstick to monitor the level. The dipstick usually has markings indicating the minimum and maximum levels. Add oil gradually until the level reaches the 'full' mark. After adding the oil, start the engine and let it run for a few minutes, then turn it off and check the oil level again after a few minutes. This allows the oil to circulate and settle, giving you an accurate reading. Paying attention to these details can save you from potential headaches down the road and keep your F-150 running like a champ. Regular oil checks, ideally every week or before any long trips, will help you catch any leaks or unusual oil consumption early on, preventing more significant problems.

Choosing the Right Oil for Your 2018 F-150 3.5L

Selecting the right oil is just as crucial as knowing the correct capacity. For the 2018 Ford F-150 3.5L, Ford recommends using SAE 5W-30 oil that meets their specifications. This type of oil is designed to provide excellent protection and performance in a wide range of temperatures. It ensures that your engine is properly lubricated, whether you're dealing with cold starts in the winter or high-temperature driving conditions in the summer. Using the recommended oil grade helps maintain the engine's efficiency and prolongs its life.

It's also important to consider whether you want to use synthetic or conventional oil. Synthetic oil generally offers superior performance and protection compared to conventional oil. It is engineered to resist breakdown at high temperatures, provides better flow in cold weather, and offers enhanced engine cleanliness. While synthetic oil is more expensive, its benefits can outweigh the cost, especially for a high-performance engine like the 3.5L EcoBoost. Conventional oil, on the other hand, is a more budget-friendly option that still provides adequate lubrication for most driving conditions. If you opt for conventional oil, make sure to adhere to the recommended oil change intervals to keep your engine in good shape. Ultimately, the choice between synthetic and conventional oil depends on your budget, driving habits, and how long you plan to keep your truck.

Step-by-Step Guide to Changing the Oil in Your 2018 F-150 3.5L

Changing your own oil can save you money and give you a better understanding of your vehicle. Here’s a step-by-step guide to help you through the process:

1. Gather Your Supplies: You'll need the correct amount of oil (6 quarts of SAE 5W-30), a new oil filter, a wrench to remove the oil filter, a socket wrench to remove the drain plug, an oil drain pan, a funnel, and gloves. It’s also a good idea to have some rags or paper towels on hand to clean up any spills.
2. Warm Up the Engine: Start the engine and let it run for a few minutes. This warms the oil, making it flow more easily. Be careful not to let the engine get too hot, as you don't want to burn yourself.
3. Position the Drain Pan: Place the oil drain pan under the oil drain plug, which is located on the bottom of the engine oil pan.
4. Remove the Drain Plug: Use the socket wrench to carefully remove the drain plug. Let the old oil drain completely into the pan. This may take 10-15 minutes.
5. Remove the Old Oil Filter: Locate the oil filter and use the oil filter wrench to loosen and remove it. Be prepared for some oil to spill when you remove the filter, so keep a rag handy.
6. Install the New Oil Filter: Lightly lubricate the rubber gasket on the new oil filter with fresh oil. Screw the new filter into place by hand until the gasket makes contact, then tighten it another half to three-quarters of a turn. Do not overtighten.
7. Reinstall the Drain Plug: Once the oil has completely drained, clean the drain plug and reinstall it. Tighten it securely with the socket wrench, but be careful not to overtighten and strip the threads.
8. Add New Oil: Open the hood and locate the oil fill cap. Remove the cap and insert the funnel. Slowly pour in 6 quarts of new oil. Be sure to use the recommended SAE 5W-30 oil.
9. Check the Oil Level: After adding the oil, replace the oil fill cap and start the engine. Let it run for a few minutes, then turn it off. Wait a few minutes for the oil to settle, then check the oil level using the dipstick. Add more oil if necessary to reach the 'full' mark.
10. Dispose of the Old Oil Properly: Take the used oil and the old oil filter to a recycling center or auto parts store for proper disposal. Do not pour used oil down the drain or into the ground.

By following these steps, you can successfully change the oil in your 2018 Ford F-150 3.5L and keep your engine running smoothly.
