The entire purpose of a standby generator is to provide power when the grid fails. But a generator with an empty fuel tank provides exactly the same protection as no generator at all — and discovering an empty tank during an active outage is a critical facility manager’s worst nightmare.
The Most Common Reason Generators Fail During Outages
Studies of generator failures during major weather events consistently find the same root cause: insufficient fuel. Unlike mechanical failures, empty tanks are entirely preventable with a proper fuel management program.
The problem isn’t that facility managers don’t know fuel is needed — it’s that generator fuel levels often aren’t part of a regular maintenance schedule, and fuel consumption during infrequent test runs doesn’t trigger enough concern to prompt refueling.
How Scheduled Generator Fueling Works
Assurance Direct Oil offers two approaches to generator fuel management:
Scheduled Preventive Refueling
A tanker visits your facility on a regular schedule (monthly, quarterly, or custom) to top up generator tanks to capacity. Most critical facility protocols specify keeping tanks above 90% — scheduled service ensures this is always the case, not just after an outage.
Remote Tank Monitoring
For facilities that want a more automated approach, we can install tank level sensors that report consumption in real time. When levels drop below a threshold you set, an automatic order is placed and a tanker is dispatched — without you lifting a finger.
Premium Diesel for Long-Term Generator Storage
Diesel stored in generator tanks for months between outages can degrade. Microbial growth, water contamination, and oxidation all reduce fuel quality, potentially causing injector fouling or startup failures when the generator is needed most.
We supply generator diesel with:
- Fuel stabilizer: Prevents oxidation and maintains fuel quality for 18–24 months
- Biocide additive: Eliminates microbial growth that can clog fuel filters
- Water dispersant: Removes water contamination from condensation
NFPA 110 Compliance
Healthcare facilities, data centers, and other regulated sites must comply with NFPA 110 standards for emergency power supply systems. Our deliveries include full documentation — fuel type, quantity, delivery date, and additive use — to satisfy inspection requirements.
Contact Assurance Direct Oil to set up a generator fueling program for your facility. Don’t wait for the next outage to discover your tanks are low.
