Are High Fuel Prices Lowering What Your Truck Is Worth?

If you own a full-size pickup or heavy-duty diesel truck, higher fuel prices may be affecting more than what you pay at the pump. They may also be putting some pressure on what your truck is worth.

According to Black Book, overall wholesale used-vehicle values fell 0.71% during the week ending September 26, 2026. Truck and SUV values declined 0.80%, while newer full-size pickups fell 1.22% and two-to-eight-year-old pickups declined 1.15%.

Black Book specifically pointed to gasoline above $4 per gallon and diesel above $6 as added pressure on the market, particularly for diesel-powered 2500- and 3500-series trucks.

Why Higher Fuel Prices Can Put Pressure on Truck Values

Vehicle values are driven partly by how many buyers want a particular type of vehicle.

When gasoline and diesel become more expensive, large trucks also become more expensive to own. Some shoppers who do not truly need the towing, hauling, or payload capability of a full-size truck may start considering smaller vehicles instead.

That shift is already appearing in the broader new-vehicle market. The Wall Street Journal recently reported increased interest in smaller SUVs and sedans as higher fuel costs influence shopping decisions.

A smaller buyer pool can eventually put downward pressure on used-truck values because dealers and wholesale buyers may become more conservative about what they are willing to pay.

One Week of Declines Does Not Mean Every Truck Lost Value

The recent numbers are worth watching, but they should not be treated as evidence that truck values are collapsing.

Black Book's 0.71% overall decline was a one-week change in wholesale values. For comparison, the market typically declined about 0.27% during the same seasonal period from 2017 through 2019. Trucks and SUVs historically averaged a decline of about 0.22%, compared with the recent 0.80% drop.

That means depreciation is currently running faster than normal, but it does not mean every truck lost the same percentage.

Your actual value can vary significantly based on factors such as trim, engine, mileage, condition, drivetrain, equipment, accident history, location, and local demand.

A heavy-duty diesel used regularly for towing may also hold up differently than a full-size pickup primarily used for commuting.

Should You Sell Your Truck or Keep It?

Higher fuel prices alone are not a good reason to sell a truck you still need.

The better question is whether continuing to own the truck still makes financial sense for you.

Selling may be worth considering if fuel costs have become difficult to justify, you no longer use the truck's towing or hauling capability, or you were already thinking about downsizing.

Keeping it may make more sense if you regularly need the truck, replacing it would create a larger financial burden, or the higher fuel expense is still manageable.

The recent market movement should be treated as one factor in the decision, not the entire decision.

Know Where You Stand Before You Decide

If you are considering selling, the most useful next step is knowing what your truck is actually worth in today's market.

If you still have a loan, compare a current offer with your payoff amount so you know whether you have positive or negative equity. We explain that process in more detail in Do You Owe More Than Your Car Is Worth?.

Sell2Nelson can provide an offer even if you are not purchasing another vehicle. That gives you a real number to compare with your payoff, fuel costs, and the cost of continuing to own the truck.

The goal is not to sell simply because fuel prices are high. It is to understand where you stand before deciding what makes the most sense next.
