Frequently Asked Questions
How does mobile fuel delivery work?
We bring the gas station to you. Once you schedule a delivery via our app, a certified technician arrives at your location and refuels your vehicle using military-grade precision and safety protocols. You don't even need to be present.
Is it safe to have fuel delivered at home?
Safety is our primary directive. Our 'Zero Fuel Left Behind' policy ensures no fuel is stored in our neighborhood overnight. We are fully DOT Hazmat compliant and use spill-prevention technology trusted by the U.S. Navy.
How do I manage my billing and account?
All account management, including plan upgrades and payment history, is handled securely through the NexxFILL member portal. Premium members receive automatic gas credits applied directly to their monthly statements.
What areas do you currently serve?
We proudly serve all of Seminole County, including Sanford, Oviedo, Lake Mary, Altamonte Springs, and Winter Springs. We are continuously expanding our mission to reach more neighborhoods.
