2022 Ford F-150 3.5L EcoBoost Oil Change — Complete DIY Guide

I used to drop my F-150 at the dealer for every oil change. Then I got the invoice for $115 on a routine 3.5L EcoBoost service — $15 in oil and a $12 filter, marked up to over a hundred bucks because I was paying for the parking lot and the guy at the counter. Never again.

The 2022 F-150 3.5L EcoBoost is one of the best-selling trucks in America, and the oil change is completely DIY-friendly. Here's everything you need to do it right the first time.

What You'll Need

• Motorcraft 5W-30 full synthetic (or equivalent Ford-spec WSS-M2C946-B1 or WSS-M2C945-A) — 6 quarts
• Motorcraft FL-820-S oil filter
• 15mm socket for drain plug
• Oil drain pan (8-quart capacity minimum)
• Torque wrench
• Oil filter cap wrench (for the cartridge-style filter housing on some trims) — or strap wrench
• Funnel
• Nitrile gloves, rags, jack stands or ramps

Drain Plug and Filter Location

The 3.5L EcoBoost drain plug is on the bottom of the oil pan — driver-side rear. The oil filter is a spin-on type mounted on the driver's side of the engine block, accessible from above or below depending on your clearance.

Important: The 3.5L EcoBoost uses an aluminum drain plug. Do not overtighten. 18 lb-ft is firm but not cranked down.

Step-by-Step

1. Warm the Oil

Run the engine for 3–4 minutes — warm oil drains faster than cold. Shut off and let it sit 5 minutes before going underneath. Don't work under a hot engine.

2. Raise the Truck

Use ramps, jack + stands, or your lift if you have one. Never work under a truck supported only by a floor jack. The F-150 sits high enough that most people can slide under on ramps without much drama.

3. Remove the Drain Plug

Position your drain pan, then break loose the 15mm drain plug counterclockwise. As it gets close to threading out, ease it slowly — hot oil will run fast once the plug clears.

Let it drain 7–10 minutes. While draining, remove the oil filler cap on top of the engine to equalize pressure and speed up drainage.

4. Replace the Oil Filter

The FL-820-S spins on counterclockwise. Expect residual oil — hold a rag underneath. Before threading on the new filter, wipe the mounting base clean and apply a thin film of fresh oil to the new rubber gasket. Hand-tighten only — 3/4 turn past gasket contact. No wrench.

5. Reinstall the Drain Plug

Thread in by hand first to avoid cross-threading aluminum threads. Torque to 18 lb-ft. If you don't have a torque wrench, snug plus 1/8 turn. The aluminum plug strips if you overtighten — trust the spec.

6. Fill with New Oil

Lower the truck. Pour 5.5 quarts through the filler cap, start the engine, let it idle 30 seconds, shut off, wait 1 minute, then check the dipstick. The 3.5L EcoBoost takes exactly 6.0 quarts — add the final half quart to reach the FULL mark.

7. Check for Leaks

With the engine at idle, look at the drain plug and filter base for any drips. The EcoBoost is particularly unforgiving of filter leaks because of the higher oil pressure these turbocharged engines run.

8. Reset the Oil Life Monitor

Press and hold the OK button on the steering wheel controls until the instrument cluster shows "Oil Life Reset." Confirm with OK. Some 2022 F-150s use a different sequence — check your owner's manual if this doesn't work.

Cost Comparison

	DIY	Dealer / Quick Lube
Motorcraft 5W-30 (6 qt)	~$30–$35	—
Motorcraft FL-820-S filter	~$10–$12	—
Labor	$0	$60–$85
Total	~$42–$47	$100–$120

Saving $55–$75 per oil change. At the EcoBoost's 10,000-mile full-synthetic interval, that's 1–2 changes per year — $55–$150 back in your pocket annually on this one job alone.

Common Mistakes

1. Using 5W-20 instead of 5W-30. Some older Ford models use 5W-20. The 2022 F-150 3.5L EcoBoost requires 5W-30. Using the wrong viscosity causes premature turbo wear.

2. Overtightening the drain plug. The aluminum oil pan threads strip easily. 18 lb-ft. Get a torque wrench.

3. Not checking the filter gasket. If the old filter gasket sticks to the block when you remove the filter, you'll get a double-gasket leak. Always check the mating surface before installing the new filter.

4. Skipping the oil life reset. The SYNC system tracks your oil life — if you don't reset it, the truck will flag a false change reminder at the wrong interval.

What's Next

If you're DIY-ing maintenance on your F-150, the next jobs worth learning are the cabin air filter (under the glove box — 5 minutes), the engine air filter (two clips on the airbox lid), and brake pad inspection at 30k miles. All straightforward jobs that don't require special tools.
