Cardlock for Fleets — From 5 Bakkies to 500 Trucks
Whether you run five bakkies around Gauteng or five hundred trucks across the platinum belt, cardlock for fleets solves the same problem: fuel spend you cannot see is fuel spend you cannot control. DieselInBulk's fleet cardlock programme covers Gauteng, the North West Province and Mpumalanga with secure cards, enforceable limits and reporting your accountant will actually enjoy.
Built for real fleet operations
Cards are issued per driver or per vehicle, each with its own PIN, fuel-type permissions, litre limits and time windows. Lost card? Deactivated instantly, replacement issued centrally. New driver? Card live within days. The controls bend around your operation — not the other way round.
The numbers fleet managers need
Every transaction feeds near-real-time reports: litres, price, site, driver, vehicle, odometer-style trends, cost per kilometre. Export to CSV or PDF, or integrate via API with your fleet management or ERP system. Exception rules flag fills that exceed tank capacity, break time windows or happen off-route.
Commercial terms that scale
Billing is consolidated monthly at wholesale-based rates, with volume discounts for larger fleets and credit terms for approved accounts. Combined with our bulk delivery and tank replenishment services, fleets can run yard tanks and cardlock off the same account — one supplier, one statement, total visibility.

Where We Deliver
DieselInBulk delivers to every city and town in three provinces — from the Johannesburg and Pretoria metros to the platinum belt, the coalfields and the Lowveld. Remote farms, mine property and construction sites are routine stops, not exceptions. If your site is in one of these provinces, we can reach it.

North West
Rustenburg, Mahikeng, Klerksdorp, Potchefstroom, Brits and the full platinum, gold and maize-belt network.
Mpumalanga

How Ordering Works
Tell us what you need
Call, WhatsApp or use the online form: your town, required litres and preferred delivery window. That is all a firm quote needs.
Approve a firm price
We confirm an all-inclusive delivered price per litre in writing — most quotes within 24–48 hours, emergencies the same day.
Receive a metered delivery
A certified driver delivers in your window, dispenses through a calibrated meter and leaves a signed manifest for your records.
Fuel Quality You Can Prove
Every litre DieselInBulk delivers is SANS-compliant diesel sourced from licensed terminals — never informal channels. We supply both 50ppm low-sulphur diesel, required by modern common-rail engines and emissions-controlled fleets, and 500ppm diesel for older plant and agricultural machinery. Certificates of analysis are available on request for any batch, which matters when an engine warranty, an insurance claim or an environmental audit depends on proving your fuel was in specification. Combined with calibrated metering and signed delivery manifests, your fuel records stay clean from terminal to tank.
FAQs
Is cardlock worth it for a small fleet?
Yes — even five vehicles benefit from consolidated billing, per-card limits and automatic transaction records.
Can we combine cardlock with bulk yard delivery?
Absolutely — many fleets run a yard tank for home-base refuelling and cards for route work, all on one account.
What does cardlock cost?
Pricing is wholesale-based per litre or account-based depending on volume — call +27 65 817 8316 for a fleet proposal.
