You’ve probably heard the phrase – America runs on diesel.
And it’s true.
Diesel engines power the trucks that move freight across the country, the equipment that builds infrastructure, and the machines that keep industries operating every day.
But here’s the part that doesn’t get talked about enough:
👉 What happens when those diesel engines don’t perform the way they should?
Because when a diesel engine goes down, it’s not just one machine: it can slow down an entire operation.
We’ve all fallen victim to common mistakes before. Whether it’s minor traffic errors (yes, left turners always yield) or any of the following gasket installation blunders, they happen to the best of us.
If you operate trucks, equipment, or a diesel shop, you don’t need anyone to tell you that parts, labor, and fuel are some of your biggest expenses. With fuel, a few cents up or down on a gallon of diesel can make or break margins on a lane, a job, or even a whole month.
In this post, we’ll walk through how diesel prices have moved over the last 25 years, then zoom in on what’s happening with diesel fuel right now in 2025 – prices, fuel quality, and what could be coming next.

Dinex Emission is a company that has been dedicated to helping diesel operators meet the high standards of the EPA for a very long time. Though the EPA’s goal is to reduce the emissions of dangerous gasses into the air, their restrictions can often make transporting goods, completing construction projects, and harvesting large crops more difficult. As an expert in the field of diesel emissions control, Dinex has long been the solution to this obstacle.
The U.S. trucking industry is firmly in the spotlight again in 2026—this time for the ongoing shortage of qualified drivers. While much of the conversation focuses on hiring, pay, and working conditions, the driver shortage has direct ripple effects on fleet operations, maintenance schedules, and demand for reliable replacement parts.
When trucks are pushed harder and maintenance windows shrink, the health of your diesel engine becomes even more important.
What’s Causing the Shortage?
Industry research estimates a gap of 60,000 drivers in 2024, with the shortage expected to climb toward 80,000+ drivers by 2026. Whether you run a small operation or a large fleet, fewer available drivers means more pressure to maximize uptime and reduce unplanned repairs.
Several Underlying Causes Include:
Aging Workforce: Many experienced truckers are nearing retirement age, and fewer young adults are entering the industry to replace them.
Demanding Lifestyle: Long hours, tight schedules, and extended time on the road make it difficult to attract new drivers. The lifestyle isn’t for everyone, and turnover remains high.
Compensation Concerns: While wages have increased in many regions, some drivers still feel pay doesn’t fully reflect the demands and responsibilities of the job. This has slowed recruitment and retention efforts across the country.
Training Barriers: Earning a CDL requires time and financial investment. For many potential drivers, the upfront cost becomes a barrier to entering the industry.
Cost of Diesel Engine Maintenance: Owner-operators face rising expenses – from insurance to diesel fuel to parts and repairs. For some, the increasing cost of maintaining a diesel engine makes staying in the industry difficult.
How the Driver Shortage Impacts Fleets and Diesel Maintenance
The shortage doesn’t just affect staffing – it directly affects how fleets run their equipment:
Increased Pressure on Existing Trucks: With fewer drivers available, fleets need every truck to stay operational. Trucks get pushed harder, and maintenance schedules become tighter or delayed.
Higher Cost of Downtime: When a truck is down, and there isn’t another driver waiting to take its place, productivity drops. Unplanned engine failure becomes even more costly in a workforce shortage environment.
Shift Toward Reliability Over Cost: Fleets are becoming less willing to gamble on low-quality parts. Instead, they look for durable, high-quality components that reduce the risk of repeat failures.
Urgency for Faster Repairs: With limited driver availability, downtime isn’t just a scheduling inconvenience—it’s a financial hit. Fleets depend heavily on suppliers who offer quick shipping, dependable stock, and accurate lead times.
Preventive Maintenance Gains Importance: Preventive maintenance is becoming a key strategy to offset risk. Replacing worn gaskets, bearings, and other engine internals before failure is more cost-effective than dealing with an unexpected breakdown.
Navigating the Road Ahead: Potential Solutions
While the driver shortage poses real challenges, there are promising steps being taken across the industry to attract and retain qualified drivers – and to support the fleets that depend on them.
Improved Working Conditions: Many fleets are investing in better pay structures, improved benefits, safer equipment, and more predictable home-time schedules. These upgrades help reduce turnover and make driving a more sustainable long-term career.
Apprenticeship & Training Programs: Streamlined CDL training, paid apprenticeships, and on-the-job mentorship are becoming more common. By reducing the upfront cost and complexity of obtaining a CDL, companies are opening the door for younger drivers who may not have considered trucking as a career.
Government Incentives: Tax credits, grant-funded training programs, and federal/state workforce initiatives are helping offset training costs for new drivers. These incentives make it easier for recruits to enter the industry and for fleets to sponsor their growth.
Affordable, Reliable Maintenance Options: One of the biggest barriers for owner-operators—and a major cost driver for fleets – is the rising price of equipment and repairs. Access to high-quality, affordable diesel engine components plays a critical role in keeping trucks on the road without overwhelming maintenance budgets.
Remanufactured and Premium Aftermarket Engine Parts: We offer a cost-effective alternative to OEM components while still delivering dependable performance. For many fleets, these options help reduce repair costs, extend equipment life, and make the total cost of ownership more manageable – especially when every operational dollar counts.
