 Demographics 
 An overview of the respondents 
 Respondents of the 2018 Fleet Maintenance Oil Study  
 manage fleets ranging from light to heavy duty, serving  
 industries from government and public safety to managing  
 common carrier and operating independent repair  
 facilities.  
 The fleets represented in this study provide a cross  
 section of all vehicle classes, with a nearly one-third  
 split for the primary vehicle class serviced in their fleets  
 between light duty, medium duty and heavy duty vehicles. 
   While a fleet may have a vehicle class category as  
 their primary vehicle type, more than half (59 percent)  
 indicated a mixed fleet.  
 The majority of vehicles are owned (86 percent) and  
 maintained in an on-site facility (71 percent), with about  
 half keeping vehicles in the fleet for more than 10 years.  
 Types of vehicles 
 Diesel and gasoline are the most common fuel types  
 among fleets, with 74 percent indicating some or all  
 vehicles run on gasoline, and 88 percent run some or all   
 diesel, a statistic that mimics other industry data showing  
 the popularity of diesel fuel among Class 4 through 8  
 vehicle purchasers. Nearly 80 percent of registered medium  
 and heavy duty vehicles in 2017 were diesel, according  
 to IHS Markit commercial vehicle research director Andrej  
 Divis at the 2018 NTEA Work Truck Show.  
 While alternative fuels lag, the study indicates a trend  
 towards fleets operating a mix of diesel and gasoline vehicles  
 along with a few alternative fuel options. As it relates  
 to alternative fuels, hybrid vehicles are the most popular  
 among all fleets, with hydrogen being the least popular.

 fleets by type, industry and size.  -Vesna Brajkovic
