Why Regular Maintenance Matters
The Risks of Neglect
Leaving tanks unchecked invites risks no operation can afford:
- Contaminated Fuel: water and sludge lead to clogged filters, microbial growth, and fuel inefficiency.
- Corrosion Hazards: tank rust weakens structural integrity and increases the risk of leaks.
- Regulatory Trouble: outdated or degraded tanks can fail inspections and incur financial penalties.
Fleet Core tackles these risks head-on, so you can focus on running your business — not worrying about your fuel system.


How Often Should Tanks Be Maintained?
Stay proactive with a schedule designed for your tank type:
- High-Use Tanks (Generators and Fleet Systems): maintenance annually ensures reliability during critical times.
- Long-Term Storage Tanks: every 2–3 years, depending on environmental conditions, prevents sediment buildup and fuel degradation.
