Diesel prices are skyrocketing, with the current price hovering around $5 per gallon. The geopolitical situation driving this increase shows no signs of a quick resolution, leaving owner operators to wonder how they can survive in this new market reality. However, by controlling two key areas - station selection and fuel consumption - owners can make a significant impact on their bottom line.
The first lever is station selection, where the difference between the most expensive and least expensive diesel along any given corridor can run as high as 50 cents per gallon. This may not seem like a lot, but for drivers who fill up twice a week, that's an extra $45 to $75 every time, adding up to significant savings over time.
Using tools like GasBuddy and Waze, which provide real-time diesel prices by station along your route, can help owner operators make informed decisions about where to fuel. The discipline is actually using these tools before you pull in, not after you're already at the pump wishing you had checked.
The regional piece matters just as much as the app. Different parts of the country carry structurally different diesel prices, with California being among the most expensive markets due to state fuel taxes and blend requirements. By knowing which regions you'll be driving through or near, you can adjust your fueling strategy accordingly.
Carrying fuel strategically is also key. If you're rolling out of a high-cost region and know you're 200 miles from a significantly cheaper market, buy enough to get there - not a full fill. This simple change can save you money on diesel costs.
The second lever is burn rate, where the range between good fuel economy and poor fuel economy for the same truck on the same route can be as much as a mile per gallon or more. At current diesel prices, one mile per gallon difference across 2,500 miles of weekly driving is roughly $200 in fuel.
Speed is the biggest variable here, with aerodynamic drag increasing exponentially with speed. Dropping from 70 miles per hour to 65 burns meaningfully less fuel, while dropping to 62 or 63 on open highway burns even less still. Treating your cruise control like a performance statement instead of a fuel economy tool can save you money.
Idle time is also a significant fuel draw, with an idling diesel engine burning somewhere between 0.8 and 1.0 gallons per hour doing nothing. Reducing idle time through the use of APU units, bunk heaters, and proper pre-planning around overnight temperatures and parking can save you money.
Tire inflation is often overlooked but is crucial to fuel economy. Under-inflated tires put more rubber contact on the road than properly inflated ones, leading to increased rolling resistance and more fuel consumption. Checking your tire pressure with a gauge and comparing it against recommended PSI can make a significant difference in your fuel economy.
By implementing these strategies, owner operators can make a real impact on their bottom line. The goal is not to become obsessive about fuel prices but to be intentional and treat every controllable cost line as if it matters. By doing so, they can protect their cash position and stay ahead of the competition in this high-fuel environment.
Disciplined fuel management is crucial in today's high-fuel environment, where every gallon counts.
