Find out how the rising cost of diesel fuel in 2026 affects the use of heavy machinery. Find out about fleet plans based on data, cost changes, and key ways to be more efficient.
Managing a successful job site requires understanding the financial impact of operations on the job site, and this is becoming more difficult. In 2023, average retail diesel prices have increased to over $5.60 per gallon nationwide. Earthmovers, crawlers, and excavators require a lot of energy to operate. Because of the projected diesel costs in 2026, many fleet managers will be required to change the way they manage operations day to day.
There is no substitute for diesel in the majority of heavy construction equipment . When operating construction equipment becomes so expensive that fuel costs account for 30% to 40% of the total operating costs, the profit from a fixed-price bid is virtually wiped out.
Earthmoving trucks and machinery run more expensive than they did the previous season. Because of this added financial constraint, the company cannot afford to continue to let the diesel engines of heavy machinery sit idling at job sites, waiting for construction materials to be delivered.
High diesel prices negatively impact contractors in two principal ways, both direct and indirect. The direct impact is from filling machine tanks. The indirect impact is through the entire industrial supply network.
Exploding Transport Surcharges
Heavy machinery needs special trailers to transport it to new job sites. Transport services are increasing their heavy-haul fuel surcharges on a weekly basis in relation to fuel price increases. Transporting a large wheel loader or crawler crane to a remote job site to even enable it to begin work will already cost a large amount of money.
Rising Raw Material Prices
Manufacturing construction materials (such as structural steel, cement, concrete blocks, and asphalt) is fuel-intensive and energy-intensive. Fuel inflation raises the baseline costs of construction materials and further impacts the margin on project costs.
Operational Tactics to Maximize Profitability of the Fleet Being Impacted
Fleet managers have implemented specific control tactics to manage their fleet to protect the profitability of their fleet from these price increases. These tactics include:
Implementing Zero-Idling Rules: Fuel costs money, and having large engines running is an expensive waste of fuel. Fleet managers monitor the time engines are idling and coach operators to turn off engines when they are not actively engaged in work.
Improving the Design of the Haul Road: Having soft, muddy or poorly graded roads causes equipment to work harder. Having a graded road to eliminate resistance requires less fuel from the entire fleet.
Updating Machine Maintenance: If a machine has clogged air filters, broken hydraulic pumps, or damaged fuel injectors, its engine will have to work pretty hard. Enforcing a precise and consistent maintenance schedule helps maximize engine efficiency and prevent unnecessary fuel waste.
The unpredictable fuel market necessitates responsive fleet management and rigorous control over expenses. The effects of escalating diesel prices are not confined to the fuel pump; all transport costs, and consequently the costs of all input materials, increase. The good news is that through smart telematics, strict policies against idling, and diligent preventive maintenance, heavy machinery operators can defend their margins and keep the projects running.
Fuel prices this year have had a greater impact on the cost of operating heavy machinery than in previous years. Why is that?
For most companies, diesel fuel is around 30% of the total cost of operating heavy machinery. When diesel prices are higher than normal, every increase in the cost of diesel fuel increases the cost of operating a heavy fleet for that hour.
For heavy machinery, do higher diesel prices increase the cost to buy additional machinery?
Yes, because higher diesel and oil prices increase the cost to produce steel and build factories.
Additionally, the cost of diesel for heavy machinery to be delivered to a factory or a worksite increases the cost to purchase a piece of heavy machinery.
What impact does a lot of idling a large piece of machinery have on a budget?
Large machinery fuel consumption is over a gallon an hour. In a large multi-machinery worksite, this amounts to thousands of dollars over the course of weeks of lost profits.
Can contractors use technology to reduce fuel costs?
Yes, modern telematics technology can track fuel consumption, idling, and operator behavior. Fleet managers can use this data to identify fuel wastage at job sites accurately.
Should contractors use electric heavy machinery to curb fuel spikes? Although more electric options for smaller machinery, such as mini-excavators, are emerging, the full electrification of heavy machinery is not yet viable. In the meantime, maximizing diesel efficiency is the most realistic approach for large fleets.
