What is Keep-Full Service? Auto-Refill Programs
Keep-full service (also called automatic delivery or will-call service) is a fuel delivery arrangement where the supplier monitors your fuel levels and delivers automatically before you run low — eliminating the need to manually check tanks and place orders. The supplier uses consumption data, degree-day calculations, or tank monitoring systems to predict when you'll need fuel.
How It Relates to Fuel Delivery
Keep-full programs work through several methods: historical consumption tracking (the supplier learns your usage patterns and schedules deliveries accordingly), degree-day calculations (for heating fuel, correlating temperature data with consumption rates), and remote tank monitoring (electronic gauges that transmit real-time tank levels to the supplier, triggering delivery when levels drop below a set threshold).
The primary benefit is runout prevention — you never have to worry about checking tanks or placing orders. This is especially critical for backup generators, where running out of fuel during an outage could mean losing power to hospitals, data centers, or other critical facilities. It's also valuable for construction sites where equipment downtime due to empty tanks costs hundreds of dollars per hour.
BettyJet offers scheduled delivery programs tailored to your consumption patterns. Whether you need weekly deliveries to a fleet yard, monthly generator top-offs, or seasonal adjustments for construction projects, we build a delivery schedule that keeps your tanks full without you having to think about it.
Why It Matters for BettyJet Customers
Running out of fuel costs more than the fuel itself — it means downtime, missed deadlines, and emergency delivery premiums. BettyJet's scheduled delivery programs keep your tanks full automatically, so you can focus on running your business instead of monitoring fuel levels.
Frequently Asked Questions
How does BettyJet know when to deliver?
We build a delivery schedule based on your consumption history, tank size, and operational needs. For critical applications, we can also work with remote tank monitoring systems that alert us when levels drop below a set threshold.
Can I still place one-time orders with keep-full service?
Absolutely. Keep-full service handles your routine deliveries, but you can always place additional orders through our customer portal or by calling (813) 694-8898 when unexpected needs arise.

ULSD stands for Ultra-Low Sulfur Diesel — a cleaner-burning diesel fuel containing no more than 15 parts per million (ppm) of sulfur. Since 2006, the EPA has required all on-road diesel sold in the United States to meet the ULSD standard, replacing Low Sulfur Diesel (LSD) which contained up to 500 ppm of sulfur.
Dyed DieselDyed diesel — also called red diesel or off-road diesel — is standard ULSD fuel that has been dyed red to indicate it is exempt from federal and state road taxes. It is chemically identical to on-road diesel but costs significantly less because the tax (typically $0.40-0.60/gallon) is not applied.
Wet HosingWet hosing is the practice of fueling vehicles or equipment directly from a mobile fuel truck rather than from a stationary storage tank. The fuel truck pulls up to each vehicle and fills it on-site — no bulk tank, no pump, no infrastructure required.
