Valero Extends Mileage as Vehicle Quality Increases

May 2008, by Cheryl Knight - Also by this author

As companies continue to find ways to get the most out of their fleet vehicles and technology continues to evolve, replacement cycles are increasingly extended. Valero Energy Corporation is one company that has extended mileage and/or service life to get a handle on fleet costs. Since extending its replacement cycle in 2004, Valero saved more than $200,000 per year for a total of $654,000 through 2007.

Randy Burwell, fleet administrator, has managed Valero Energy Corporation’s fleet for more than 10 years. He and a staff of two handle 1,845 vehicles (262 cars, 56 SUVs, 70 vans, 1,337 light trucks, 75 medium trucks, and 45 heavy vehicles), including Ford F-150s, F-250s, and F-350s; GM 1500s and 2500s; and Dodge 1500s.

Headquartered in San Antonio, Valero has more than 22,000 employees and generated 2007 revenues of more than $95 billion. The company owns and operates 17 refineries throughout the U.S., Canada, and the Caribbean, with a combined throughput capacity of approximately 3.1 million barrels per day, making it the largest refiner in North America.

Valero is also one of the nation’s largest retail operators, with approximately 5,800 retail and branded wholesale outlets in the U.S., Canada, and the Caribbean under various brand names, including Valero, Diamond Shamrock, Shamrock, Ultramar, and Beacon.

Valero Extends Vehicle Replacement to Control Costs

Valero achieved several benefits after increasing its vehicle replacement in 2004, including savings in costs and labor required on vehicles.

“When our fleet cost-per-mile averages are benchmarked against our industry, we fall in the lower percentiles,” Burwell said. “This is a good indicator that the decision to postpone vehicle replacement has been cost-effective, at least when compared to the industry.”

Sixty-five percent of the company’s units are owned, and the remaining 35 percent are leased through PHH Arval. Replacement cycles have been extended on most of the company’s vehicles, including:

  • Cars: 65,000 miles/four years to 85,000 miles/five years.
  • Light trucks: 85,000 miles/four years to 115,000 miles/five years.
  • Diesel trucks: 115,000 miles/five years to 150,000 miles/six years.

“Mileage limits were raised due to a study that indicated a monetary value in extending the vehicle life,” Burwell said.

The fleet team determined the most effective replacement parameters by first conducting a mathematical analysis to determine at what point the average monthly cost of maintenance and repairs exceeded the average monthly depreciation cost. By using the actual cost history of Valero vehicles (including resale values and maintenance expenses), the team arrived at a beginning “optimal” numerical range for replacement.

The next step included the additional calculation and analysis of certain non-vehicle factors impacted by the replacement criteria, such as the potential of productivity loss for employees if their vehicle suffers an increase/decrease in unscheduled maintenance breakdown, and the addition or reduction in planning and administrative hours required for actually managing the vehicle replacements.

“The final step included adjustments for soft issues, such as the potential company name brand impact of having older vehicles in the field, employee satisfaction, seasonality, full utilization of vehicle warranty, and Valero’s expectations about the future,” Burwell said. “We also had to take into account possible business growth, motor company incentives, and new technology.”

When deciding how long to keep the fleet vehicles in service, the fleet team had a delicate balance to maintain.

“Several criteria are used when determining the optimal replacement cycle,” Burwell said. “It has long been known that depreciation is the leading fleet expense (44 percent for Valero), and the way to lower this expense is to keep vehicles longer. However, keeping units too long is a costly endeavor. Average maintenance cost should not exceed average depreciation cost.”

Other factors Burwell examined were safety, maintenance history, resale, and driver satisfaction. The vehicles must be maintained to assure safety in all cases.
