Whether truck drivers pay for their own gas depends on how they’re employed. Company drivers on a W-2 don’t pay for diesel; the carrier covers every gallon through a company-issued fuel card. Owner-operators pay for all of their own fuel out of pocket. Lease-purchase drivers also pay for their fuel, but usually through automatic deductions the carrier takes from their weekly settlement. Since fuel makes up roughly a quarter of total trucking operating costs, that difference shapes almost everything about how a driver earns.
Company Drivers Don’t Pay for Fuel
If you drive as a W-2 employee, the carrier owns the truck, assigns your routes, and pays for the diesel. You fuel up using a company card from a provider like Comdata or WEX, and the charge goes straight to your employer’s account. No receipts to keep, no expenses to report, no exposure to diesel price swings.
Most carriers ask you to enter a PIN and your current odometer reading at the pump. That lets the company track fuel efficiency across the fleet and flag anything unusual. Some carriers also pay per-mile bonuses when drivers hit targets for low idle time, steady speed, and efficient fueling habits, so you can share in the savings without sharing in the cost.
Owner-Operators Pay for Every Gallon
If you own your truck and work as an independent contractor, every drop of diesel is on you. A typical long-haul tractor carries two tanks holding a combined 300 gallons. At the national average retail diesel price of roughly $3.72 per gallon in early 2026, a full fill-up runs about $1,116.1U.S. Energy Information Administration. Weekly U.S. No 2 Diesel Retail Prices
Price changes hit your margin immediately. If diesel rises fifty cents a gallon and you drive 2,500 miles a week at six miles per gallon, you burn about 417 gallons, adding roughly $208 to your weekly costs. That comes straight out of profit. Route planning and fuel apps that find the cheapest stops along your route can soften the blow, but the risk is always yours.
Reefer Fuel
If you haul temperature-controlled freight, the refrigeration unit on the trailer runs on its own diesel supply, separate from the truck’s main tanks. That reefer fuel is your responsibility, and depending on run time and temperature setting it can add a meaningful expense on top of your regular diesel bill. Factor it into your per-mile rate when bidding on refrigerated loads.
Idling
A heavy-duty engine burns roughly 0.8 gallons of diesel per hour at idle, with a range from 0.6 to 1.5 gallons per hour depending on the engine and accessories.2U.S. Department of Energy. Long-Haul Truck Idling Burns Up Profits Running your engine overnight for heat or air conditioning during a ten-hour rest period can cost $25 to $35 a night. Over a year, habitual idling can add thousands in fuel costs. Auxiliary power units and other idle-reduction technology cut that expense significantly. Roughly 20 states also enforce anti-idling laws for commercial vehicles, with limits from three to fifteen minutes and fines that can reach several hundred dollars per violation.
Lease-Purchase Drivers: You Pay, but Through the Carrier
Lease-purchase programs let you work toward owning a truck while operating under a carrier’s authority. You function as an independent contractor, and you pay for all fuel. Most lease-purchase contracts require you to use a carrier-issued fuel card, and the carrier deducts fuel charges directly from your weekly settlement before you see any pay. The upside is access to the carrier’s negotiated fuel network, which often saves anywhere from about $0.10 to $0.45 per gallon at major truck stop chains compared to retail.
Federal regulations require the lease agreement to spell out exactly which party is responsible for fuel costs, fuel taxes, empty mileage, tolls, permits, and other operating expenses. The lease must also list every charge-back item the carrier can deduct from your settlement and explain how each one is calculated.3eCFR. 49 CFR 376.12 Lease Requirements
Escrow Account Protections
Some lease-purchase agreements include escrow accounts where the carrier withholds part of your pay each week for maintenance, fuel reserves, or other obligations. Federal rules treat that escrow money as yours. The carrier must keep it in an interest-bearing account, provide an accounting of every transaction, and return any remaining balance plus interest when the relationship ends.3eCFR. 49 CFR 376.12 Lease Requirements A 2025 federal task force report found that some carriers have created questionable charges to drain driver escrow accounts, so review your settlement statements carefully.4FMCSA.

How Fuel Surcharges Help Owner-Operators Recover Costs
A fuel surcharge is an extra fee added to a freight bill that helps whoever pays for the diesel absorb price spikes. The surcharge is calculated using a formula tied to the national average diesel price published weekly by the U.S. Energy Information Administration.1U.S. Energy Information Administration. Weekly U.S. No 2 Diesel Retail Prices Each contract sets a baseline diesel price, often between $1.25 and $1.50 per gallon. When the current national average is above that baseline, a per-mile surcharge kicks in.
The exact amount varies by contract. As one example from the Department of Energy’s freight rate schedule, when diesel averaged $3.56 per gallon, the truckload fuel surcharge worked out to $0.27 per mile.5Department of Energy. CY 2025 DOE Weekly Fuel Surcharge Quick Reference Guide On a 500-mile haul, that would add $135 to the freight bill. The surcharge is separate from the base hauling rate and adjusts weekly as prices move.
For owner-operators, the surcharge is a critical piece of revenue. Your contract should specify the exact price index, the baseline price, and the formula so there’s no ambiguity about what you’re owed. If a broker or carrier bundles the surcharge into the base rate instead of itemizing it, you lose visibility into whether the fuel cost is actually being covered.
Deadhead Miles Come Out of Your Pocket
Deadhead miles, the distance you drive empty between loads, burn fuel without producing freight revenue. For owner-operators, you pay full fuel cost for every deadhead mile. Fuel surcharges generally apply only to loaded miles, so empty repositioning is a pure expense.
Some carriers offer company drivers partial reimbursement for deadhead mileage, often in the range of $0.60 to $0.90 per mile, but this varies widely. If your contract or load assignment doesn’t address deadhead compensation, factor unreimbursed fuel and wear into your per-mile math before accepting a load. Planning return loads to minimize deadhead is one of the most effective ways owner-operators protect their fuel budget.
Tax Deductions If You Pay Your Own Fuel
Owner-operators and lease-purchase drivers who pay for their own diesel can deduct the full cost as a business expense on Schedule C of Form 1040. Line 9 covers vehicle operating expenses, including fuel, oil, repairs, insurance, tires, and registration fees.6Internal Revenue Service. 2025 Instructions for Schedule C Form 1040 You must use the actual expense method (not the standard mileage rate) if you operate five or more vehicles simultaneously, and you cannot switch to actual expenses after previously using the standard mileage rate on a leased vehicle.7Internal Revenue Service. Topic No. 510, Business Use of Car
Keep every fuel receipt and match it to a trip. The IRS can disallow deductions you can’t document, and if an audit turns up unsupported deductions or unreported income, you could owe back taxes plus interest and penalties. Company drivers don’t need to worry about any of this; the carrier bought the fuel, and there’s nothing on your side to deduct.
