Ford F-150 Gas Tank Size: Everything We Need to Know Before Filling Up

When we talk about the Ford F-150, we’re not just talking about a pickup truck — we’re talking about an American icon. And while horsepower, towing capacity, and trim levels usually steal the spotlight, there’s one quietly critical spec that shapes real-world ownership more than most people realize: the Ford F-150 gas tank size.

How far can we go between fill-ups? How does tank size change across trims, cab styles, and model years? And why does Ford offer multiple fuel tank options in the first place? Let’s break it all down, calmly, clearly, and without the fluff.

Why Gas Tank Size Actually Matters More Than We Think

Fuel tank capacity isn’t just a number on a spec sheet — it’s freedom.

A larger gas tank means:

• Fewer stops on long road trips
• Better range when towing or hauling
• Less anxiety in rural or off-road driving
• More flexibility for work trucks and fleets

On the flip side, a smaller tank can mean lighter weight and slightly better efficiency in city driving. Ford understands this balance, which is why the F-150 doesn’t come with a one-size-fits-all fuel tank.

Ford F-150 Gas Tank Size Overview (At a Glance)

Before diving deep, here’s the high-level picture.

Standard Ford F-150 Gas Tank Sizes

• 23 gallons – Base and lighter configurations
• 26 gallons – Most common mid-range option
• 36 gallons – Extended range tank (long-distance king)

Those numbers may look simple, but the story behind them isn’t.

How Ford Chooses Gas Tank Sizes

Ford doesn’t randomly assign tank sizes. Several factors shape what tank you get.

Cab Configuration

• Regular Cab
• SuperCab
• SuperCrew

Bed Length

• 5.5-foot bed
• 6.5-foot bed
• 8-foot bed

Drivetrain

• Rear-wheel drive (RWD)
• Four-wheel drive (4WD)

Trim Level

• XL
• XLT
• Lariat
• King Ranch
• Platinum
• Limited
• Raptor

Each combination affects frame layout, weight distribution, and space under the truck — where the fuel tank lives.

Ford F-150 Gas Tank Size by Model Year

While the core sizes remain consistent, availability has shifted slightly over the years.

2015–2020 Ford F-150 Gas Tank Sizes

• 23-gallon tank (standard on many trims)
• 26-gallon tank (optional or standard depending on setup)
• 36-gallon extended range tank (optional)

2021–Present Ford F-150 Gas Tank Sizes

Ford kept the same capacity options but made the 36-gallon tank more widely available, especially on SuperCrew models.

That’s a subtle change, but one long-distance drivers appreciate.

Gas Tank Size by Cab Style

Regular Cab F-150

Regular Cab models tend to prioritize simplicity and payload.

• Common tank size: 23 gallons
• Optional upgrades: 26 gallons
• Rare but possible: 36 gallons (specific setups)

This setup works well for fleet trucks and short-distance workhorses.

SuperCab F-150

SuperCab strikes a balance between passenger space and practicality.

• Standard tank: 26 gallons
• Optional: 36-gallon extended range

For many owners, this is the sweet spot.

SuperCrew F-150

This is where the F-150 becomes a road-trip machine.

• Standard: 26 gallons
• Optional: 36 gallons

Most SuperCrew buyers opt for the bigger tank — and for good reason.

Ford F-150 Gas Tank Size by Bed Length

5.5-Foot Bed

• Common with SuperCrew
• Often paired with 26-gallon tank
• 36-gallon tank available

6.5-Foot Bed

• Most flexible configuration
• Supports all three tank sizes

8-Foot Bed

• Mostly Regular or SuperCab
• Typically 26 or 36 gallons

Longer beds usually mean more space for larger tanks.

Does Engine Choice Affect Gas Tank Size?

Here’s where myths creep in.

Short Answer

No — engine choice does not directly determine tank size.

Long Answer

Indirectly, yes.

Different engines are paired with certain trims and drivetrains, which then influence available tank sizes. But the tank itself isn’t tied to whether you choose:

• 3.3L V6
• 2.7L EcoBoost
• 3.5L EcoBoost
• 5.0L V8
• 3.5L PowerBoost Hybrid

Ford F-150 Hybrid (PowerBoost) Gas Tank Size

The hybrid model deserves special attention.

PowerBoost Fuel Tank

• 30.6 gallons

Why the odd number? Because Ford needed to balance battery placement, electric motors, and frame components — and they nailed it.

Why It Matters

Combined with the hybrid system, the PowerBoost delivers up to 700+ miles of range in real-world driving. That’s borderline ridiculous — in the best way.

Extended Range 36-Gallon Tank: Is It Worth It?

Let’s be honest — this is the tank most people want.

Benefits of the 36-Gallon Tank

• Fewer fill-ups
• Ideal for towing
• Perfect for long commutes
• Excellent for road trips

Potential Downsides

• Slightly higher cost
• More fuel weight when full

For most owners, the benefits far outweigh the drawbacks.

Real-World Driving Range by Tank Size

Range depends on driving habits, terrain, and engine choice — but here’s a realistic estimate.

23-Gallon Tank

• City driving: ~400 miles
• Highway cruising: ~500 miles

26-Gallon Tank

• Mixed driving: ~550 miles
• Highway: ~600 miles

36-Gallon Tank

• Highway: 700+ miles
• Towing: still impressively long

It’s like carrying an extra coffee thermos — you just don’t need to stop as often.

Fuel Economy vs Tank Size: Clearing the Confusion

A bigger tank does not reduce fuel economy.

Fuel economy is measured in miles per gallon — not gallons per tank. A larger tank simply means:

• More fuel onboard
• Longer driving range

Think of it as a bigger backpack, not heavier shoes.

If you’re unsure which tank your truck has, here’s how we can find out.

Easy Methods

• Check the window sticker
• Review the owner’s manual
• Look up your VIN on Ford’s website

Quick Rule of Thumb

If your F-150 feels like it runs forever between fill-ups, chances are it’s packing the 36-gallon tank.

Does Towing Affect Fuel Range?

Absolutely — and dramatically.

When towing:

• Fuel consumption increases
• Driving range drops
• Larger tanks become invaluable

This is where the extended range tank really earns its keep.

Gas Tank Size and Payload Capacity

A full tank adds weight.

Fuel Weight Breakdown

• Gas weighs ~6.3 lbs per gallon
• 36 gallons = ~227 lbs

Ford factors this into payload ratings, so you’re not breaking rules — just something to keep in mind.

Common Myths About Ford F-150 Gas Tanks

Let’s clear the air.

Myth 1: Bigger Tanks Hurt MPG

False.

Myth 2: You Can Easily Upgrade Later

Mostly false — tank swaps are complex and expensive.

Myth 3: All F-150s Have the Same Tank

Very false.

Who Should Choose Which Tank Size?

23-Gallon Tank Is Ideal If

• You drive mostly in the city
• Short commutes
• Light use

26-Gallon Tank Is Best For

• Daily drivers
• Weekend trips
• Balanced usage

36-Gallon Tank Is Perfect For

Ford gives us options for a reason. The key is choosing the one that fits how we actually drive — not just how the brochure looks.
