Cut Your Transport Fuel Costs by 15%: Complete Guide to Logistics Fuel Supply in South Africa

🚛 From overnight depot refuelling to cross-border fleet supply—your complete guide to transport company fuel management

I once worked with a logistics company in Johannesburg that operated 80 long-haul trucks. They were spending over R2 million monthly on diesel—but they had no idea if they were getting good prices, no control over driver fuel purchases, and no visibility into fuel consumption across their fleet. Their drivers were buying fuel at retail prices along routes, paying R2-R3 more per litre than wholesale. They were bleeding money.

After we helped them implement proper fleet fueling solutions, their monthly fuel bill dropped by nearly R400,000. That’s R4.8 million annually—straight to the bottom line.

For South African logistics companies, bulk fuel for logistics companies is often the single largest operating expense after payroll. Getting it right can mean the difference between profitability and losses. Getting it wrong can destroy your margins.

This comprehensive guide covers everything you need to know about transport company fuel supply, including diesel delivery for truck fleets Johannesburg and other major hubs, wet hosing benefits, overnight fuelling strategies, fleet fueling best practices, and cost optimization.

⚠️ Why Bulk Fuel Matters for Logistics Companies

Diesel is the lifeblood of South African logistics. When fuel costs are optimized, margins improve. When fuel supply fails, deliveries stop and contracts are lost.

Why bulk fuel for logistics companies demands strategic attention:

• Fuel is your largest variable cost: Typically 25-40% of operating expenses for logistics companies.
• Price volatility: Fuel price fluctuations directly impact profit margins.
• Driver behavior: Without controls, driver fuel purchases can be inefficient or fraudulent.
• Route variability: Different routes, different fuel needs—requires flexible supply solutions.
• Cross-border operations: Different fuel regulations and pricing across borders.
• Depot constraints: Not all depots have on-site fueling infrastructure.
• Rebate opportunities: Logistics companies may qualify for fuel levy refunds on cross-border operations.

🚚 Fleet Fueling Options for Logistics Companies

Different logistics operations need different fueling solutions. Here are the main options for transport company fuel supply:

Depot-based bulk storage (most common):

• On-site fuel storage tanks at your depot
• Scheduled bulk deliveries directly to your tanks
• Best for: Companies with dedicated depots and predictable return schedules
• Lowest cost per litre (wholesale + delivery)
• Requires capital investment in storage tanks

Wet hosing (mobile refuelling):

• Wet hosing providers refuel trucks at your depot or on-site
• No on-site storage tanks required
• Supplier brings bowser and refuels fleet
• Best for: Depots without storage, or supplementing existing storage
• Higher per-litre cost but no capital investment

Overnight fuelling:

• Overnight fuelling services refuel trucks while drivers rest
• Trucks are ready to go each morning
• Best for: Fleets that return to depot nightly
• Improves morning dispatch efficiency

Fuel card programs:

• Drivers use branded fuel cards at partner stations
• Centralized billing and reporting
• Best for: Long-haul fleets that can’t return to depot daily
• Higher cost per litre than depot fueling but offers convenience

Route-based fueling:

• Pre-arranged fueling at specific points along common routes
• Negotiated wholesale rates at partner stations
• Best for: Fixed routes with predictable fueling points
• Balance of convenience and cost

Which fueling option is right for you?

• Return-to-depot fleets: Depot-based bulk storage + overnight fuelling = lowest cost
• Mixed operations: Depot fueling for local trucks + fuel cards for long-haul
• No depot storage: Wet hosing for depot refuelling + fuel cards for en-route
• Cross-border: Fuel cards with cross-border acceptance + route-based agreements

⛽ Wet Hosing: Mobile Refuelling for Truck Fleets

Wet hosing is increasingly popular for logistics companies without on-site storage. Here’s what you need to know:

What is wet hosing?

Wet hosing is a mobile refuelling service where a supplier brings a fuel bowser to your depot or location and refuels your trucks directly. “Wet” means the supplier provides both the equipment and the fuel. “Hosing” refers to the hose used to transfer fuel.

Benefits of wet hosing for logistics companies:

• No capital investment: No need to purchase storage tanks or fueling infrastructure
• No compliance burden: Supplier manages storage compliance and safety
• Flexible scheduling: Adjust fueling times based on fleet returns
• Scalable: Easy to increase or decrease as fleet size changes
• Reduced theft risk: No on-site fuel storage to secure
• Professional management: Supplier handles metering, quality, and documentation

Wet hosing costs (indicative):

Is wet hosing right for your fleet?

• Yes, if: You don’t have on-site storage, want to avoid capital investment, have variable fleet sizes, or want to test fueling needs before investing in tanks.
• Consider depot storage if: You have very high volume (50,000L+ monthly), a permanent depot, and capital available—per-litre costs will be lower.

🌙 Overnight Fuelling: Refuel While Your Trucks Rest

Overnight fuelling is a game-changer for logistics efficiency. Here’s how it works and why it matters:

What is overnight fuelling?

Overnight fuelling means your trucks are refuelled while parked at your depot overnight. Drivers arrive after their shift, park, and go home. Fueling happens during the night. Trucks are ready to go with full tanks when drivers arrive in the morning.

Benefits of overnight fuelling:

• No driver fueling time: Drivers don’t spend 15-30 minutes refuelling before departure—saves 1-2 hours weekly per driver
• Morning dispatch efficiency: All trucks ready immediately at shift start
• Better driver utilization: Drivers start delivering sooner
• Reduced overtime: Less morning prep time means earlier departures
• Lower driver frustration: Drivers appreciate not having to refuel after long shifts
• Improved security: Refuelling happens in controlled depot environment, not at public stations

How overnight fuelling works:

1. Drivers park trucks in designated fueling area after shift
2. Driver submits fuel order (or automated system tracks levels)
3. Overnight fueling team refuels trucks during night
4. Trucks are ready with full tanks when drivers arrive morning
5. Drivers complete pre-trip inspection and depart immediately

Overnight fuelling options:

• In-house: Your staff refuels from on-site storage. Requires 24/7 fueling staff.
• Outsourced wet hosing: Supplier sends team overnight to refuel fleet. No staff management required.
• Automated depot fueling: Card-operated pumps with driver self-service (not truly overnight unless drivers stay late).

Is overnight fuelling worth it?

For fleets of 20+ trucks returning to depot nightly, overnight fuelling typically pays for itself through improved driver utilization alone. Calculate: 20 trucks × 20 minutes daily fueling time × 220 operating days = 1,467 hours annually of driver time saved. At R150/hour driver cost = R220,000+ annual saving.
