Cardlock Fueling vs Mobile Fuel Delivery: Complete Comparison
Cardlock stations offer fleet-exclusive access to fuel 24/7 — no lines behind consumer vehicles, no attendants, just swipe and pump. They have been the go-to fleet fueling solution for decades. But mobile fuel delivery has emerged as a serious competitor by eliminating the one thing cardlock cannot: the trip to the station.
Both options beat retail gas stations on pricing and security. The question is whether the remaining operational overhead of cardlock — the drive time, the routing, the driver productivity loss — justifies the per-gallon savings compared to fuel that comes directly to your yard.
This comparison puts real numbers behind the cardlock vs mobile fueling decision.
Winner: Mobile Fuel Delivery
For fleets operating from a central yard or fixed job sites, mobile delivery wins on total cost. Cardlock pricing may be 2-5 cents per gallon cheaper than mobile delivery, but the drive time to stations costs $15-$25 per truck per day in driver wages and lost productivity. A 30-truck fleet paying $20/day in station time spends $600/day — or $156,000/year — just getting to and from cardlock stations. Mobile delivery eliminates that cost entirely.
Feature Comparison
| Feature | Mobile Fuel Delivery | Cardlock Stations |
|---|---|---|
| Per-Gallon Fuel Cost | Slightly higher than cardlock (bulk pricing) | Lowest non-wholesale price available |
| Driver Time at Station | Zero — fueling happens at your location | 20-45 minutes per truck per day |
| 24/7 Availability | Scheduled or on-demand delivery | Self-service 24/7 |
| Station Location Dependency | None — fuel comes to you | Must route near a cardlock location |
| Fuel Theft Risk | Near zero — metered, receipted delivery | Low but possible — card sharing, unauthorized use |
| Total Cost of Fueling | Lower — no drive time, no productivity loss | Higher when labor costs are included |
When to Choose Each Option
Choose Mobile Fuel Delivery When:
- Your fleet parks at a central yard or job site overnight
- You operate 15 or more vehicles from one location
- Driver productivity is a measurable KPI
- You want to eliminate all station-related downtime
- Fuel theft or unauthorized fueling is a concern
Choose Cardlock Stations When:
- Your vehicles operate on dispersed routes without a central base
- Cardlock stations are conveniently located on existing routes
- You have fewer than 10 vehicles and the savings do not justify delivery fees
- Your drivers need to refuel mid-route during long-haul trips

Our metered delivery system tracks exactly how many gallons go into each vehicle, giving you the same per-truck consumption data that cardlock systems provide — without any of the station overhead.
Frequently Asked Questions
How much does cardlock fueling actually cost per truck per day?
Beyond the per-gallon fuel cost, cardlock fueling costs $15-$25 per truck per day in driver wages and lost productivity. A driver spending 30 minutes at a station earning $25/hour costs $12.50 in wages alone, plus the revenue-generating work they are not doing during that time.
Can mobile fueling completely replace cardlock for a large fleet?
Yes, for fleets that return to a central location daily. BettyJet services fleets of 10 to 200+ vehicles with overnight wet hosing. Fleets with long-haul routes may keep cardlock access for on-road refueling while using mobile delivery for their primary yard.
Is mobile fuel delivery available for diesel and gasoline?
Yes. BettyJet delivers ULSD (ultra-low sulfur diesel), dyed off-road diesel, regular unleaded gasoline, premium gasoline, and DEF (diesel exhaust fluid). All fuel types are available for scheduled or on-demand delivery.
