The 2005 Ford F150 pickup truck remains a stout work truck, with its brawn, towing and payload capacity, and brute strength. Of course, if you want this nearly two-decade old truck to keep on humming, you’ll need to know its engine oil capacity, which is 6 quarts (5.7 liters) for the V6 engine, or 7 quarts (6.6 liters) for the V8 engine.
  • The 2005 Ford F150 requires Motorcraft 5W-20 engine oil.
  • The engine oil capacity is 6 quarts for the V6 engine, and 7 quarts for the V8 engine.
  • You can save money by changing the oil in your 2005 Ford F150 at home.
  • Never throw dirty oil or dirty rags into the trash—put them into a sealed container and dispose of them at your local recycling center.

2005 Ford F150 engine oil capacity

So, let’s get down to brass tacks—how much oil does a 2005 F150 engine need?
This depends on which engine your 2005 F150 has. The Ford F150’s 6.6-liter V6 engine has an oil capacity of 6 quarts, while the Ford F150’s 6.6-liter V8 engine has an oil capacity of 7 quarts. That said, don’t confuse these figures for the 6.6-liter displacement for both engines. The engine displacement simply refers to the amount of volume the engine’s cylinders take up—it’s got nothing to do with the engine’s oil capacity, so don’t confuse the two.

What kind of oil does a 2005 Ford F150 need?

Both of the 2005 F150’s engine options require the same kind of oil. Both require
Motorcraft SAE 5W-20 synthetic engine oil
. You’ll have to buy two 5-quart bottles to ensure your truck gets the engine oil it needs. Since this oil is Ford’s recommendation for both the V6 and V8 engines, it should be the only engine oil you pour into your 2005 F150, no matter which engine you have.
So what do all those numbers and letters mean? We’ll explain. First off, those numbers refer to the oil’s thickness, or viscosity. The W stands for winter, the 5 refers to the oil’s low viscosity at the frigid temperature of 0°F, and the 20 refers to this oil staying decently thin at super hot temperatures. SAE stands for Society of Automotive Engineers, i.e. the scientists who come up with the engine oil codes.
So as you’ve probably figured out, the oil you should be putting into your F150 will perform well under both cold and hot conditions. It’s low viscosity means the oil will stay relatively thin in almost all climates, meaning it will keep flowing and inflict minimal wear and tear on your engine.

How often to change oil on a 2005 Ford F150

So, now that you know what kind of engine oil (and how much of it) goes into your 2005 Ford F150, you’ll need to roll up those sleeves, stiffen your spine, and gird your loins—it’s time to
change your oil
You should change your Ford’s engine oil every 5,000 miles or, if you don’t drive a lot, every six months or so. Changing your oil at these intervals will ensure your engine oil stays clean and functional.
It’s always a good idea to physically check your oil to ensure it's in good working order. Get into the habit of popping the hood and taking a look at the oil’s condition every other time you fill up, or about once a month. Look, smell, or listen for the following signs that will signal an oil change is nigh:
  • Motor oil needing to be changed will look dark brown or black with the consistency of soda (Clean oil looks light brown or amber, resembling a cup of tea).
  • Motor oil feels gritty, dirty, or coarse 
  • You hear unfamiliar noises coming from the engine 
  • You detect new smells, especially anything smelling like oil, smoke, or burning
  • You notice changes in your truck’s performance

How to change your oil and oil filter

Since you can tell when your oil needs changing simply by looking at it, it's time to do the deed and, as they say north of the border, “git’er done”.
Grab yourself a socket wrench, a drain pan, and a filter wrench, which is designed to remove the old filter. Be sure you buy a replacement filter and a few bottles of the correct Motorcraft 5W-20 engine oil.
To start, run your F150’s engine for a few minutes until it reaches normal operating temperature. In normal weather, this will take only about 5 minutes. Now, kill the engine, pop the hood, and do the following:
  • Remove the oil fill cap
  • Slide underneath the engine (yes, you’ll have to do this, sorry) and remove both the oil drain bolt and washer—the drain pan will catch the old oil draining out of the engine 
  • Remove the old oil filter and continue to allow the oil to drain 
  • Install the replacement filter
  • Use a new washer to tighten the oil drain bolt back into place, tightening to 29 lb-ft
  • With your new oil, refill the engine and replace the fill cap
Get the new oil to fill the filter by turning the engine on for about 30 seconds. Check the dipstick to ensure you’ve put enough oil into your engine. If the dipstick tells you your rig doesn't have enough oil, add some more.
Once you’re done, take a quick peek around and under the truck to ensure there are no signs of oil leakage. If you followed our instructions to a “T” and everything has gone to plan, the
oil pressure light
on the dashboard should be off.
Now, the cleanup—place all dirty rags and dirty oil into a sealed, recyclable container, and bring that container to your local recycling center. Do not put dirty oil or oily rags into the garbage.
