The 2018 Ford F-150 3.5L Oil Capacity: The Magic Number

Alright, let's get down to brass tacks: What is the 2018 Ford F-150 3.5L oil capacity? The answer is 6 quarts (5.7 liters). That's the amount of oil you'll need, including the new oil filter, to perform a proper oil change. It's super important to use the right amount of oil. Too little, and your engine won't be properly lubricated, leading to increased friction and wear. Too much, and you could damage seals or cause other issues. Therefore, be precise! Always double-check your owner's manual for the most accurate information. Ford typically provides detailed instructions and specifications, including the recommended oil type, filter, and torque specs for the drain plug. This documentation is your best friend when it comes to any maintenance task. If you've misplaced your manual, don't worry – you can often find a digital copy online.

Remember, when you're changing your oil, it's not just about the quantity. The quality of the oil and filter also matters. Using the right type of oil, as specified by Ford, is crucial for optimal engine performance and longevity. Using a high-quality oil filter will also make a difference. These filters trap impurities and prevent them from circulating through your engine. Using the right oil and filter is a small investment that will pay off in the long run. In addition to the oil capacity, you’ll also want to know the recommended oil change intervals. Many modern engines, including the 3.5L EcoBoost, can go longer between changes than older engines, thanks to advancements in oil technology. However, it's still essential to follow the manufacturer's recommendations or adjust based on your driving conditions.

Furthermore, when adding the oil, take your time. Pour the oil slowly and carefully, allowing it to settle before checking the level with the dipstick. Don’t just dump it all in at once! This prevents overfilling and allows you to accurately measure the level. Once you've added the oil and replaced the oil filter, start the engine and let it run for a few minutes. Check for any leaks around the drain plug and oil filter. Turn off the engine and let it sit for a few minutes, then recheck the oil level with the dipstick. Add more oil if needed to reach the “full” mark on the dipstick. If you’re not comfortable doing this yourself, there's no shame in taking your truck to a trusted mechanic. They can handle the oil change and ensure everything is done correctly. Finally, remember to dispose of your used oil and filter responsibly. Many auto parts stores offer recycling programs.
