Why It’s Time to Replace Tractors Sooner

">Many fleet managers have long followed the golden rule of running a tractor to one million miles before investing in a replacement. But it may be time to part ways with that magic number.
Yes, purchasing or leasing a new tractor can be an intimidating expense. As improvements in fuel standards, telematics, and safety hit the market, however, the “one million mile” heavy-truck cycling practice actually puts long-term savings at risk.
At Element Fleet, we encourage customers to consider cycling through old tractors sooner, often leading to lower total cost of ownership at the end of the day.
Major improvements, major savings
The one million mile rule has a fairly simple origin. Tractors are expensive, so fleets that run them for as long as possible are increasing cost-effectiveness. Such thinking is now shortsighted because, just like passenger vehicles, heavy-truck fleet tractors get better and better each year. Whether it's fuel, performance or safety, these improvements enable savings throughout the lifecycle of a heavy truck.
As a major ongoing expense, fuel is often the largest savings opportunity that urges customers to cycle tractors earlier. Diesel fuel is the biggest operating cost for trucking companies and as prices increase globally so do figures on the expense sheet. For most fleets, the dramatically improved fuel economy accompanying most new tractors offers a significant economic upside.
To put it simply, imagine that a fleet of 10 trucks each running 100,000 miles a year is seeing an average 7 miles per gallon. Even just a one mpg improvement would save nearly 20,000 gallons of fuel each year. This alone is a significant savings opportunity.
Perhaps more obvious than fuel savings is the decreased maintenance required for new-and-improved tractors. Maintenance costs tend to rise based on a tractor's age, and cycling out sooner can help fleet managers avoid ...Read the rest of this story
