Summer Ultimate D

COMMERCIAL SERVICES

Fleet Fueling

With 24/7 on-site fueling from Santoro Oil, your fleet and equipment stay operational around the clock. Whether you’re running a construction site, managing a fleet yard, or operating a critical facility, our team delivers fuel directly to your tanks, trucks, or machinery to reduce downtime and eliminate the need for off-site refueling. We work on your schedule, even overnight, weekends, or early mornings, so your team starts each shift ready to go. Our dependable service not only saves time and labor but also boosts efficiency and helps reduce operating costs.

Tank Monitoring

Santoro Oil’s tank monitoring system helps you stay on top of your fuel supply without the guesswork. Using a small wireless transmitter, you can monitor real-time fuel levels in every tank on demand. That means no more unexpected runouts or wasted trips to check.

With fuel tank monitoring, you can:

  • Always have the fuel you need and when you need it
  • Know exactly how much fuel is in your tanks
  • Stop wasting time with extra trips to refill
  • No more checking tanks by hand
  • Keep your site working without delays
  • Don’t let fuel run out and slow you down

Our smart monitoring system also lets you:

  • You can choose how often reports are sent
  • Set alerts for when tank levels get too high or too low
  • Get warnings for when tanks are being filled or emptied too fast
  • Pick the dial style that fits your tank (big, small, tall, or for special fuels)
  • See signal strength and system info on the screen

Keep your fleet running without the downtime. Santoro Oil’s Wet Fueling service brings the fuel directly to your vehicles, equipment, or jobsite. Whether you manage delivery trucks, construction machinery, or generators, our team ensures your tanks are filled on-site and on schedule.

Benefits of Wet Fueling:

  • Productivity Boost: Crews can focus on the job instead of managing fuel runs.
