Cardlock Fuel Solutions for South African Fleets
Cardlock fuel solutions replace cash, slips and guesswork with a secure card, a litre limit and a digital record for every transaction. DieselInBulk provides cardlock fuel solutions for fleets operating across Gauteng, the North West Province and Mpumalanga — giving transport, mining, construction and agricultural operators total control over their second-biggest cost.
Control that starts at the pump
Each card is configured to your rules: diesel only, maximum litres per transaction, daily and monthly caps, allowed hours. Drivers refuel at designated DieselInBulk cardlock points and partner locations across our three provinces — many open extended hours for long-haul routes — while every transaction is logged against driver, vehicle, site, litres and price.
Reporting that finds the leaks
Fuel shrinkage hides in unrecorded fills, side-fuelling and after-hours detours. Cardlock reporting surfaces all of it: exception alerts, cost-per-vehicle and cost-per-kilometre views, and CSV/PDF/API exports straight into your fleet or accounting system. Most fleets recover more in prevented losses than the programme costs.
Billing that simplifies month-end
One consolidated monthly statement for the whole fleet, with agreed credit terms for approved accounts. No more reconciling boxes of garage slips — just clean, coded transactions ready for your accountant.

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.

Johannesburg, Pretoria, Sandton, Midrand, the East Rand, West Rand and Vaal Triangle — every town, with same-day capability around our Springs base.
North West
Rustenburg, Mahikeng, Klerksdorp, Potchefstroom, Brits and the full platinum, gold and maize-belt network.
Mpumalanga
Nelspruit (Mbombela), Witbank (Emalahleni), Secunda, Middelburg, Ermelo and the Lowveld farming and forestry towns.
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.
