Why Fuel Is Your Biggest Variable Cost

For most owner operators, fuel accounts for 30 to 40 percent of total operating costs. Unlike truck payments or insurance premiums, fuel costs fluctuate constantly based on market prices, your routes, and your driving habits. That makes fuel management one of the highest-leverage areas for improving your bottom line.

Use a Fuel Card to Save at the Pump

A commercial fuel card gives you discounted diesel prices at partner truck stops across the country. Popular options include the EFS card, Comdata, and fleet cards through major fuel networks. Savings of 10 to 30 cents per gallon add up fast across thousands of miles per month.

Many carriers and dispatch services can give you access to fuel discount programs as part of their service package. Ask your dispatch provider if they offer fuel card access or network discounts.

Plan Your Fuel Stops Strategically

Fuel prices vary significantly by state. States like Texas, Missouri, and Oklahoma typically have lower diesel prices than California, Pennsylvania, or New York. With a little route planning, you can time your fill-ups in lower-tax states and reduce your average cost per gallon significantly over the course of a month.

Use apps like GasBuddy, Trucker Path, or your fuel card’s network locator to compare prices in advance
Fill up in cheaper states before entering high-tax areas
Avoid filling up at rural truck stops without fuel card discounts when a network location is nearby

Improve Your Fuel Economy on the Road

Better driving habits can improve fuel economy by 15 to 20 percent without any equipment changes. Here are the most impactful adjustments:

Reduce highway speed: Driving at 60 mph instead of 70 mph can improve fuel economy by up to 20 percent
Use cruise control: Consistent speed burns less fuel than constant acceleration and braking
Limit idle time: Excessive idling burns roughly one gallon per hour — use APU systems or stop idling whenever possible
Maintain proper tire pressure: Under-inflated tires increase rolling resistance and fuel consumption
Keep up with air filter maintenance: A clogged air filter forces the engine to work harder and burn more fuel

Optimize Your Load Planning to Cut Fuel Waste

Every empty mile is a mile you paid for without earning anything. Reducing deadhead miles is one of the most effective ways to lower your overall fuel cost per loaded mile. Work with a dispatcher who plans your routes around backhauls and round trips rather than one-way loads that leave you repositioning empty.

At Nexloads, our dispatch team actively looks for lanes that minimize empty miles between loads, which directly reduces your total fuel spend without touching your driving habits.

Track Your Cost Per Mile

Knowing your fuel cost per mile lets you evaluate every load accurately. A load paying $2.50 per mile looks different depending on whether your fuel cost is $0.45 or $0.65 per mile. Keep a simple weekly log of gallons purchased, miles driven, and total fuel spend so you always know where you stand.

Consider IFTA Reporting Efficiency

If you operate across multiple states, you file quarterly IFTA reports to calculate fuel tax owed or credited based on where you drove versus where you fueled. Buying fuel in states with lower fuel tax rates than where you drive can result in IFTA credits. Your fuel card provider can often generate IFTA-ready reports to simplify this process.

Small Changes Add Up to Big Savings

Fuel management is not about one big change. It is the combination of using a fuel card, planning your fill-up locations, adjusting your driving speed, and reducing deadhead miles that produces meaningful savings month over month.
