2016 Ford F150 Gas Tank Size – Identifying Your Capacity And Range
The 2016 Ford F-150 typically comes with either a 23-gallon standard tank or a 36-gallon extended-range tank. Knowing your specific capacity is essential for calculating your maximum towing distance and understanding how much fuel remains when your low-fuel light illuminates.
Do you ever find yourself staring at the fuel gauge, wondering if you can make it to the next exit while hauling a heavy trailer? You are not alone, as many truck owners are surprised to learn that the 2016 ford f150 gas tank size varies significantly depending on the original factory configuration.
Identifying your specific fuel capacity is the first step in mastering your truck’s logistics, whether you are a daily commuter or a dedicated off-roader. In this guide, we will break down the different tank options, show you how to verify your equipment, and explain how fuel weight affects your payload.
By the end of this article, you will have a technician’s understanding of your fuel system, allowing you to plan your trips with total confidence. Let’s dive into the specs and see what Ford tucked under the chassis of your 2016 rig.
Understanding Your 2016 ford f150 gas tank size
In 2016, Ford simplified the fuel tank options for the F-150 lineup, but there is still some variation based on the wheelbase and the packages selected at the time of purchase. Most owners will find they have one of two primary capacities.
The standard 2016 ford f150 gas tank size for most trim levels, including the XL, XLT, and Lariat, is 23 gallons. This size was designed to balance daily driving range with the overall curb weight of the vehicle.
However, for those who opted for the Max Trailer Tow Package or specifically requested the upgrade, Ford offered a massive 36-gallon extended-range fuel tank. This larger tank is a favorite among overlanders and long-distance towers because it significantly reduces the frequency of fuel stops.
The 23-Gallon Standard Tank
The 23-gallon tank is the “bread and butter” of the F-150 line. It provides a respectable range for the 2.7L EcoBoost and the 5.0L V8 engines, especially when the truck is not under a heavy load.
If you primarily use your truck for commuting or light hardware store runs, this tank is usually more than sufficient. It also helps keep the truck’s gross vehicle weight rating (GVWR) lower, which can slightly improve your available payload capacity.
The 36-Gallon Extended-Range Tank
The 36-gallon tank is often considered the “gold standard” for the F-150. If you have the 3.5L EcoBoost engine, which can be thirsty under boost, this extra capacity is a game-changer.
With 36 gallons of fuel, an F-150 getting 18 MPG can theoretically travel over 600 miles on a single fill-up. This is particularly useful in remote areas where gas stations are few and far between.
How to Verify Your Specific Fuel Capacity
If you bought your truck used, you might not know which tank is installed. There are several reliable ways to determine your 2016 ford f150 gas tank size without crawling under the truck with a tape measure.
The most straightforward method is to look at your original window sticker if you still have it. The fuel tank size is usually listed under the “Optional Equipment” or “Functional” sections of the document.
If the window sticker is long gone, don’t worry. You can use the digital tools available to every Ford owner or use a bit of practical observation at the local gas station.
Using the VIN Decoder
Every vehicle has a unique “fingerprint” known as the Vehicle Identification Number (VIN). You can enter your VIN into an online Ford VIN decoder to see the original build sheet for your truck.
This build sheet will explicitly state whether the truck left the factory with the 23-gallon or 36-gallon unit. This is the most accurate method because it accounts for any special packages the original owner might have added.
The Gas Pump Method
A more “hands-on” way to check is to wait until your low-fuel light comes on and then fill the tank to the brim. If the pump clicks off at around 19 or 20 gallons, you almost certainly have the 23-gallon tank.
If you find yourself pumping 30 to 32 gallons before the nozzle clicks, you have the extended-range version. Remember that there is always a reserve capacity of a few gallons left when the light comes on to protect the fuel pump.
Visual Inspection of the Tank
If you are comfortable sliding under your truck, you can visually identify the tank size. The 36-gallon tank is significantly longer than the 23-gallon version, often extending much further toward the front of the truck along the frame rail.
The 23-gallon tank is more compact and leaves more open space along the driver-side frame. While you’re down there, check for any skid plates that might be protecting the tank if you have the FX4 Off-Road package.
The Relationship Between Tank Size and Payload
One detail many DIY mechanics overlook is how fuel weight impacts the truck’s performance and legal carrying capacity. Gasoline weighs approximately 6.07 pounds per gallon at room temperature.
A full 23-gallon tank adds about 140 pounds to your truck’s weight. However, a full 36-gallon tank adds nearly 219 pounds. That is a 79-pound difference that comes directly out of your available payload.
If you are pushing your truck to the limit with a heavy tongue weight or a bed full of gravel, you must account for this extra weight. For off-roaders, this extra weight also shifts the center of gravity slightly, which can be felt during technical maneuvers.
Range Calculations for Different Engines
Knowing your 2016 ford f150 gas tank size is only half the battle; you also need to know how that translates to miles on the road. The 2016 F-150 had several engine options, each with different fuel appetites.
The 3.5L Ti-VCT V6 is generally the most efficient but lacks the raw torque of the EcoBoost or V8. The 5.0L V8 offers consistent mileage, while the EcoBoost engines vary wildly depending on how heavy your right foot is.
- 2.7L EcoBoost: With a 23-gallon tank, expect a highway range of roughly 480 miles. With 36 gallons, that jumps to over 750 miles.
- 5.0L V8: This engine typically gets around 17-21 MPG. On a 36-gallon tank, you are looking at a safe 600-mile cruising range.
- 3.5L EcoBoost: When towing, MPG can drop to 10-12. This is where the 36-gallon tank becomes essential, providing 360 miles of range versus only 230 miles with the standard tank.
Common Problems and Maintenance for F-150 Fuel Systems
Regardless of your tank size, the fuel system requires proper care to ensure your truck starts every morning. The 2016 model year is generally reliable, but there are a few things to keep an eye on.
One common issue is the fuel pump control module, which can sometimes fail due to corrosion or electrical faults. If your truck cranks but won’t start, this is a common culprit that a DIYer can often replace with basic hand tools.
Another point of interest is the “Distance to Empty” (DTE) calculation on your dashboard. If you have recently upgraded your tank or changed your tire size, this calculation might be inaccurate until the computer is recalibrated.
Protecting the Fuel Pump
Modern fuel pumps are submerged in the gas tank, using the fuel itself as a coolant. If you constantly run your truck until the tank is nearly bone-dry, the pump can overheat.
To extend the life of your pump, try to refill when you hit the quarter-tank mark. This is especially important for the 36-gallon tank, as the pump has to work harder to move fuel across the longer tank structure.
The Capless Fuel Fill System
The 2016 F-150 features Ford’s “Easy Fuel” capless system. While convenient, it can sometimes collect dust or debris around the seal. If you do a lot of off-roading in dusty conditions, periodically wipe the area with a clean rag.
If the seal doesn’t close perfectly, it can trigger a Check Engine Light (CEL) for an EVAP system leak. A quick cleaning usually resolves the issue without a trip to the mechanic.
Upgrading Your Fuel Capacity
If you discovered that you have the 23-gallon tank but your lifestyle demands more range, you aren’t stuck. Many owners choose to swap their standard tank for the OEM 36-gallon version.
This is a popular “bolt-on” upgrade, though it does require some work. You will need the larger tank, a new fuel pump assembly (the sending unit arm is longer), and potentially some new heat shields or mounting straps.
After the physical installation, you must use a tool like FORScan to update the truck’s computer. This tells the dashboard that it now has a larger capacity, ensuring your fuel gauge and DTE readings are accurate.
Frequently Asked Questions About 2016 Ford F150 Gas Tank Size
Can I put a 36-gallon tank in a Regular Cab F-150?
Generally, the 36-gallon tank is designed for the 145-inch, 157-inch, and 163-inch wheelbases. The short-wheelbase Regular Cab (122-inch) often lacks the physical space between the frame crossmembers to fit the larger tank without significant modification.
Does the tank size affect my fuel economy?
Indirectly, yes. A larger tank full of fuel adds weight, which can slightly decrease your MPG. However, the difference is usually negligible compared to the benefits of a longer driving range.
How much fuel is left when the “Miles to E” hits zero?
Ford builds in a buffer of approximately 1.5 to 2.5 gallons. However, you should never rely on this. Running the tank that low can suck up sediment from the bottom of the tank and clog your fuel injectors.
Is there a diesel tank option for the 2016 model?
No, the Power Stroke diesel engine was not introduced to the F-150 lineup until the 2018 model year. All 2016 F-150 tanks are designed specifically for gasoline.
Final Thoughts for the 2016 F-150 Owner
Understanding your 2016 ford f150 gas tank size is more than just a trivia point; it is a vital part of being a responsible truck owner. Whether you are navigating a job site or exploring a mountain trail, knowing your fuel limits keeps you safe and on schedule.
If you find that your current 23-gallon tank is holding you back, consider the OEM swap or look into aftermarket high-capacity tanks from reputable brands. Always prioritize safety when working around fuel systems, and never hesitate to consult a professional if a fuel line or electrical connection looks questionable.
Take care of your fuel system, keep your filters clean, and enjoy the legendary capability of your Ford truck. Stay safe out there on the road, and may your tank always be full enough for the journey ahead!
