Fleet fuel use

The cost of fuel is one of the most significant operating expenses for mobile service truck fleets, in some cases comprising more than half of the budget. The larger the fleet, the faster your fuel costs add up.

You can’t control the price of fuel, but as fleet manager you can make sure your service technicians and trucks use fuel more efficiently. Fleets of all types and sizes can reap the benefits when they choose solutions and technologies that reduce fuel usage. Stop wasting fuel with these five tips to improve efficiency and reduce truck fuel costs. 

1. Pay attention to preventive maintenance 

Maintenance is an important part of keeping your truck running optimally and efficiently. Cleaning the air filters and diesel particulate filters (DPF) regularly, changing engine oil and keeping tire pressure at recommended levels all play a role in fuel economy. For example, under-inflated tires can reduce gas mileage by about 0.2% for every 1-psi drop in average tire pressure. A dirty DPF increases the need for greater engine output that burns more fuel. DPF-related increases in fuel consumption can range from 4.5% to 7%. The bottom line? A well-maintained truck is a more efficient truck.


2. Stop unnecessary truck engine idling

Turning off truck engines on the jobsite can deliver significant fuel savings. Running these high-horsepower engines to drive your air, hydraulic or other power needs is extremely inefficient. It decreases the truck’s overall fuel economy and eats into profits. For example, engines in these typical truck configurations can burn up to 0.9 gallons of fuel per hour while idling. This may not seem like much, but the extra fuel adds up. A PTO-equipped system uses 34% more fuel on average to supply air, hydraulic and other power needs compared to an APU (auxiliary power unit) system.   


3. Choose truck equipment and technologies wisely  

Select fuel-efficient equipment and technologies. Using APU-type equipment to run your tools, such as air and hydraulics, is an easy way to minimize fuel spend. But not all of these systems are created equal. Look for solutions with technologies that maximize fuel efficiency, such as equipment that automatically shuts off when not in use. Some equipment also matches engine output to the load — so it’s not constantly running at the highest rpm and burning more fuel. These technologies can pay for themselves quickly, usually in less than one year. When specifying the truck, don’t just consider the acquisition cost; it’s also important to think about your long-term ROI.

4. Lightweight and rightsize your fleet

Reducing vehicle weight does make a difference for fuel economy and savings. Every additional 100 pounds on a vehicle reduces the average miles per gallon by 1%, according to the EPA. Using telematics on your fleet and the associated power equipment lets you analyze metrics and review equipment usage data to help ensure you have the right equipment as well as the right size equipment. You should also evaluate if smaller, lighter trucks that use less fuel will work for your fleet and still allow techs to carry the tools and equipment they need to get jobs done efficiently. In addition to using a lower class of truck — a class 5 versus a class 7, for example — consider bodies constructed of alternative materials, which can potentially reduce weight considerably and greatly increase fuel efficiency on the road. Choosing lightweight tools and equipment also helps lower your overall truck weight.


5. Evaluate and optimize your truck equipment

Another way to reduce overall truck weight — and increase fuel efficiency — is to audit the onboard equipment, remove any that is unnecessary or not frequently used, and rightsize what is necessary. Understand whether or not you need a crane and, if so, choose the appropriate size. You also need to know whether you need a welding solution and at what output. Once you have those answers, look for tools and equipment that can be combined to save space and weight on the truck, such as using a single APU-type unit rather than several separate components (like an air compressor, welder/generator and battery charge/jump packs). An all-in-one APU can save up to 550 pounds compared to using a PTO-driven air compressor and an engine-driven welder/generator.

Reducing truck fleet fuel costs

Fuel costs are likely some of the biggest expenses in your work truck fleet. While you can’t control the price you pay at the pump, you can control how your fleet uses fuel.
