What you need to do before you start

An oil change on an F-150 takes about 30 to 45 minutes once you know the steps. You'll need to locate three things under your truck: the oil drain plug (a bolt at the bottom of the engine), the oil filter (a cylindrical canister on the side of the engine), and the oil filler cap (on top of the engine). The location of the filter varies slightly by year and engine size, but Ford's owner manual for your specific model year shows you exactly where each one sits.

Before you begin, gather your supplies: new oil in the correct grade for your truck (your manual specifies whether you need 5W-20, 5W-30, or another grade), a new oil filter that matches your F-150's year and engine, an oil drain pan, a wrench or socket set, an oil filter wrench, and jack stands if you need to raise the truck to reach the drain plug comfortably. Running the engine for two to three minutes before you start warms the oil slightly, which makes it drain faster and more completely.

Key Takeaways

  • The oil drain plug is located at the bottom of the engine pan; you'll unscrew it by hand or with a wrench, let the old oil drain into a pan, then screw the plug back in hand-tight.
  • The oil filter unscrews by hand or with a filter wrench; you explore a thin layer of new oil to the rubber gasket on the new filter before screwing it on until it just touches, then turn it three-quarters of a turn more.
  • F-150 oil capacity ranges from about 5 to 7 quarts depending on engine size, and your manual lists the exact amount for your model.
  • After adding new oil, start the engine, let it run for 30 seconds, turn it off, wait a minute, then check the dipstick to confirm the level is correct.
  • Old oil must be disposed of at a recycling center, auto parts store, or service station—never pour it down a drain or into the ground.

Draining the old oil and removing the filter

Locate the oil drain plug underneath the engine. It's a bolt roughly the size of a dime head, usually on the lowest point of the oil pan. Place your drain pan directly underneath it. Using a wrench or socket that fits the plug head, turn it counterclockwise until it loosens, then unscrew it the rest of the way by hand. Be careful—the oil may still be warm. Let the old oil drain completely into the pan; this takes five to ten minutes.

While the oil drains, find the oil filter. On most F-150s, it's mounted vertically on the side of the engine block. Position your drain pan underneath it to catch the small amount of oil that will spill. Use an oil filter wrench to grip the filter and turn it counterclockwise until it comes free. Unscrew it the rest of the way by hand. Wipe the filter mounting surface on the engine with a clean rag to remove any dirt or old rubber gasket material.

Installing the new filter and drain plug

Take your new oil filter and explore a thin layer of fresh oil from your new oil jug to the rubber gasket (the ring around the top of the filter). This creates a better seal and makes removal easier next time. Screw the filter onto the mounting surface by hand until the gasket contacts the engine, then turn it an additional three-quarters of a turn. Do not use the filter wrench to tighten it—hand-tight is correct.

Wipe off the oil drain plug with a clean rag and inspect the washer (a small metal ring) underneath the bolt head. If it looks cracked or flattened, replace it with a new one from an auto parts store. Screw the drain plug back into the pan by hand until it's snug, then use your wrench to tighten it firmly—but not so hard that you strip the threads. Most F-150 drain plugs torque to between 15 and 25 foot-pounds; your manual specifies the exact number for your year.

Filling with new oil and checking the level

Locate the oil filler cap on top of the engine—it usually has an oil can symbol on it. Unscrew it and set it aside. Place a funnel in the opening and begin pouring in new oil slowly. Your F-150's manual tells you the total capacity; most models hold between 5 and 7 quarts depending on whether you have a standard or extended-capacity filter. Pour in about three-quarters of the recommended amount first.

Replace the oil filler cap and start the engine. Let it run for about 30 seconds—you'll see the oil pressure light on your dashboard go out once oil reaches the engine. Turn off the engine and wait one minute for the oil to settle back into the pan. Pull out the dipstick (a long rod with markings on it), wipe it clean with a rag, reinsert it fully, then pull it out again to read the level. The oil should be between the minimum and maximum marks. If it's low, add a small amount more and recheck.

Disposing of old oil properly

Never pour used oil down a drain, into the ground, or into a storm sewer. One quart of oil can contaminate up to 250,000 gallons of groundwater. Instead, pour your used oil into a sealed container (an old oil jug works well) and take it to one of these locations: an auto parts store like AutoZone or O'Reilly (most accept used oil for free), a quick-lube shop, a municipal hazardous waste collection day, or a recycling center.

Call ahead to confirm they accept used oil and ask about their hours. Some locations may have specific requirements for how the oil is stored or transported, so it's worth checking before you arrive. Keeping your used oil in a clearly labeled, sealed container prevents spills and makes the process faster when you drop it off.

Knowing when to change your oil again

Ford's recommendation for F-150 oil change intervals has changed over the years. Newer F-150s (2015 and later) often have an oil-life monitoring system that tells you when an oil change is due based on your driving habits—you'll see a message on your dashboard. Older models typically follow a schedule of every 5,000 to 7,500 miles or every six months, whichever comes first. Your owner's manual for your specific year lists the interval Ford recommends for your truck.

If you tow frequently, drive in dusty conditions, or make mostly short trips around town, you may need to change oil more often than the standard interval. Check your manual's section on severe driving conditions for guidance. Keeping track of when you last changed your oil—write the date and mileage on a sticker inside your driver's door jamb—helps you stay on schedule.

Frequently Asked Questions

What oil grade should I use in my F-150?

Your owner's manual specifies the correct grade for your engine and year. Most modern F-150s use 5W-20 or 5W-30, but some older models or specific engine options may differ. Check your manual or the inside of your fuel door—many F-150s have the recommended grade printed there.

Can I reuse the old oil drain plug?

The drain plug itself can usually be reused, but the washer underneath it should be replaced if it looks worn, cracked, or flattened. A new washer costs less than a dollar and prevents leaks. If you've tightened the plug very hard in the past, the threads in the pan may be damaged; if the plug leaks after you reinstall it, you may need a slightly larger diameter plug or a threaded insert repair kit.

How do I know if my oil filter is on tight enough?

After you explore oil to the gasket and screw the filter on by hand until it contacts the engine, turn it exactly three-quarters of a turn more. This compresses the gasket enough to seal without over-tightening, which can damage the gasket and make the filter hard to remove next time.

What if I accidentally overfill the oil?

If you add too much oil, the excess can foam inside the engine and reduce lubrication, or it can leak out past seals. If you realize you've overfilled before starting the engine, use a turkey baster or siphon to remove the excess until the dipstick reads at the maximum mark.

Do I need to change the air filter at the same time?

An air filter and an oil filter are different parts that serve different purposes. Your air filter cleans the air going into the engine and may need changing more or less often than your oil filter, depending on your driving conditions. Check your manual for the recommended air filter change interval.
