Fleet Fueling No matter how large or small your company’s fleet may be, Sinclaire Enterprises will provide on-site diesel fuel delivery to your trucks and your equipment in a timely and professional manner. We offer a flexible schedule, giving you the option to have your fleet fueled in the morning, afternoon, or evening. We work hand in hand with transportation companies and manager’s to help accommodate each business’s unique delivery needs. All of our diesel fuel, both on-road and off-road, is ultra low sulfur diesel fuel at 15ppm. Invoicing System Options Our customers have the option of how they would prefer to be invoiced. The most common way to be invoiced is a total-gallons-used invoicing system. With this system, your business would receive one invoice for all the fuel purchased in one line. The second option we offer is our itemized invoicing system that breaks down each individual vehicle’s fuel consumption, enabling your company to run reports fuel usage per individual truck and providing better analytics in general. Diesel Exhaust Fluid (DEF) As well as providing our companies with diesel fuel, we can replenish your trucks with DEF. Per regulations, all new diesel fueled trucks require the use of DEF to run properly. We began providing this service back in 2015 and it is available to you upon request. If you have any questions regarding our fleet fueling programs and incentives, please call our office at 508-668-8200.
