If your Ford F-150 has crossed 150,000 miles, it is natural to start wondering whether you should keep driving it or trade it for something newer.

At 165,000 miles, 180,000 miles, or even 200,000 miles, however, the odometer alone does not answer that question. A well-maintained high-mileage F-150 with a healthy drivetrain and solid frame can be a much better financial proposition than replacing it simply because it has passed an arbitrary mileage threshold.

On the other hand, an older truck that is beginning to need repeated major repairs, has serious rust, or is causing frequent downtime can quickly become more expensive and inconvenient than it first appears.

The right decision comes down to the condition of the truck, its maintenance history, expected repairs, how much reliability matters to you, and how much value you place on the safety and technology improvements found in newer F-150s.

Is 150,000 Miles Too Much for an F-150?

Not necessarily.

There is no mileage at which an F-150 suddenly becomes worn out. Two trucks with 165,000 miles can be in dramatically different condition depending on maintenance, climate, towing use, previous repairs, idle time, driving conditions, and how they were treated by previous owners.

A better question is: What condition are the expensive parts of the truck in today?

Those include:

• Engine
• Transmission
• Frame and body
• Differentials and transfer case
• Cooling system
• Steering and suspension
• Air conditioning
• Electrical system

A truck with 165,000 miles that has been maintained properly and needs little beyond routine service may still have plenty of useful life left. A neglected truck at the same mileage could be entering a period of expensive repairs.

The Case for Keeping Your Current F-150

1. The Truck You Already Own Is Usually Much Cheaper

The biggest advantage of keeping an older F-150 is simple: you do not have to buy another truck.

A newer used F-150 can require tens of thousands of dollars in cash or financing, while a new truck can cost substantially more once trim levels and options are added.

Keeping an older truck means avoiding or reducing:

• Vehicle payments
• Sales tax
• Financing costs
• Higher registration costs
• Potentially higher insurance premiums
• Depreciation on a newer vehicle

That gives an older truck a surprisingly large repair budget before replacing it becomes cheaper.

For example, a $3,000 repair that keeps a truck running reliably for another two years effectively costs about $125 per month over that period. That is far below the monthly ownership cost of many newer trucks.

2. You Know the Truck’s History

A familiar high-mileage truck can sometimes be less risky than an unfamiliar lower-mileage truck.

If you have owned your F-150 for years, you may already know:

• How regularly the oil was changed
• Whether the transmission has been serviced
• What suspension parts have been replaced
• Whether it has overheated
• Whether it has been used for heavy towing
• Which problems have already been repaired

Buying another used F-150 resets much of that knowledge. A replacement with 80,000 miles is not automatically better than a well-maintained truck with 165,000 miles.

3. Depreciation Has Slowed Considerably

An older F-150 has already experienced most of the steep depreciation that occurs earlier in a vehicle’s life.

A newer truck still has much more value available to lose. Even if a high-mileage F-150 requires occasional repairs, low depreciation can help offset those expenses.

4. Cosmetic Wear Matters Less

An older pickup also has a practical advantage for owners who actually use their trucks.

Scratches in the bed, rock chips, dirty interiors, parking-lot dings, and wear from tools or equipment are easier to accept on a truck that is already more than a decade old.

That can make an older F-150 especially useful as a work truck, towing vehicle, hunting truck, or second vehicle.

The Case Against Keeping a High-Mileage F-150

1. Age-Related Repairs Begin to Add Up

At this stage of a truck’s life, mileage is only part of the issue. Rubber, plastic, seals, bearings, electrical connectors, suspension components, hoses, and accessories have also been exposed to more than a decade of heat and vibration.

Even with a healthy engine, owners may begin seeing repairs involving components such as:

• Wheel bearings
• Control arms and ball joints
• Shocks and struts
• Water pumps
• Radiators and hoses
• Alternators and starters
• A/C components
• Sensors
• Driveshaft or U-joint components

None of these individually means a truck is finished. The problem occurs when several begin failing within a short period.

2. Major Drivetrain Repairs Can Change the Math

A suspension repair or water pump usually does not justify replacing an otherwise good truck.

An engine or transmission problem deserves more consideration because the repair can represent a meaningful percentage of the truck’s value.

Before replacing the truck, however, compare the repair with the actual cost of the alternative, not just the truck’s resale value.

Spending several thousand dollars repairing a paid-off truck may still be cheaper than spending $25,000, $35,000, or considerably more on another F-150.

2014 F-150 Owners Should Pay Attention at 150,000 Miles

Ford’s maintenance schedule becomes especially relevant for 2014 F-150 owners approaching this mileage.

Ford specifies several major maintenance items at 150,000 miles, including changing the automatic transmission fluid and filter, changing axle fluid, changing transfer-case fluid on four-wheel-drive trucks, and replacing the accessory drive belt if it has not already been replaced. Spark plugs were scheduled earlier at 97,500 miles, while the initial coolant replacement was scheduled at 105,000 miles.

That means a 160,000- or 170,000-mile truck with incomplete service records deserves a thorough maintenance review before assuming that it is simply “getting old.”

Some problems at this mileage may be the result of overdue maintenance rather than the end of the truck’s useful life.

Check the 2014 6R80 Transmission Recall

Owners of 2014 F-150s should also check their VIN for open recalls.

Ford recall 24S37 covers certain 2014 F-150 trucks equipped with the 6R80 six-speed automatic transmission. Ford and NHTSA reported that a failure involving the transmission’s output-speed-sensor signal could cause an unintended downshift into first gear. An abrupt downshift can cause the rear wheels to slow or slide and increase the risk of losing control.

This does not mean every 2014 F-150 has the defect. Recall eligibility should be checked using the individual truck’s VIN.
