If you run a transport, construction, or logistics business in South Africa, you already feel it every time you pull into a fuel station. Diesel isn't just expensive — it's unpredictably expensive. And with global oil prices climbing again, the pressure on South African truck operators is only increasing.

But here's what most people in the industry miss: rising oil prices don't just affect your running costs. They completely change the financial logic of how you should be acquiring trucks. At Boschies CC in Jet Park, Gauteng, we've been helping business owners navigate exactly these kinds of market pressures for over 30 years. This article breaks down why rising oil prices actually make the case for second hand trucks stronger — not weaker.

Why Oil Prices Hit South African Truckers So Hard

South Africa imports most of its crude oil, meaning every movement in the global Brent crude price flows directly into what you pay at the diesel pump. The rand's weakness against the dollar amplifies this further — a weaker rand means more rands per litre, regardless of what happens to the oil price in dollar terms.

For a truck doing 8,000 km per month at 35 litres per 100 km, every R1.00 increase in the diesel price costs an extra R2,800 per month per truck. Run a fleet of five trucks? That's R14,000 per month in additional fuel cost — before you've touched tyres, maintenance, driver wages, or finance repayments.

This is the environment we're operating in right now. And it demands a smarter approach to capital allocation than ever before.

The True Cost of a New Truck in a High Oil Price Environment

When fuel prices rise, the total cost of ownership equation shifts significantly. Here's why a brand-new truck becomes an even harder sell when oil is expensive:

1. The Finance Repayment Doesn't Change — But Everything Else Does

A new Class 8 rigid truck in South Africa in 2026 costs anywhere from R1.8 million to R4.5 million depending on spec, brand, and configuration. At current interest rates, that's a monthly finance repayment that can comfortably exceed R40,000 to R80,000 per month over a 60-month term.

Now add rising fuel costs, tyre replacements, insurance, licensing, and driver wages on top of that. In a high oil price environment, the fixed cost of a premium new truck finance repayment becomes a dangerous anchor on your cash flow — especially if your customers are also under pressure and trying to cut transport costs.

2. Depreciation Hits Hardest in the First Three Years

A new commercial truck loses roughly 20–30% of its value in the first year and another significant chunk in years two and three. You absorb this depreciation whether the truck earns money or sits in the yard. When your fuel bill is already elevated, taking that depreciation hit on top makes the numbers very difficult to justify.

A well-selected second hand truck has already had that steep early depreciation absorbed by its previous owner. You buy it at a price that reflects its true current market value — not the inflated new-unit premium.

3. New Trucks Come with Features You're Paying For But May Not Need

Modern new trucks are loaded with technology — advanced telematics, Euro 6 emission systems, complex driver assistance packages, automated gearboxes with expensive service requirements. In a stable, low-cost operating environment, these features can add value. In a tight, high-fuel-cost environment, they add cost and complexity without necessarily adding proportional revenue.

Why Second Hand Trucks Win When Oil is Expensive

Let's be very direct about this: rising oil prices don't make trucking more expensive across the board in an equal way. They make high-capital-cost trucking more expensive. And the best way to reduce your capital cost is to buy quality second hand.

Lower Purchase Price = Lower Finance Repayment = Better Cash Flow

A quality second hand truck at Boschies CC might cost R350,000 to R900,000 for a fully operational rigid tipper, dropside, or horse — compared to R2 million+ for the new equivalent. The difference in monthly finance repayments can be R25,000 to R50,000 per month. That's money that stays in your business to absorb rising fuel costs, rather than flowing to a finance house.

Better cash flow gives you resilience. Resilience is exactly what you need when running costs are unpredictable.

Faster Break-Even

When your capital outlay is lower, you reach your break-even point faster. In a high operating cost environment, getting to break-even quickly is not just a financial preference — it's a survival strategy. A second hand truck working on day one can be earning its keep while a new truck is still in the early stages of its repayment schedule.

Reinvest the Savings Into Fuel Efficiency Improvements

Here's a powerful strategy we see successful operators using: they buy quality second hand trucks at a fraction of new prices, then use the capital saved to invest in fuel efficiency improvements. This can include:

• Professional engine tuning — optimising injection timing and fuel maps for efficiency rather than peak power
• Aerodynamic improvements — cab deflectors, side skirts, and mud flaps that reduce drag
• Tyre management — switching to fuel-efficient tyre compounds and maintaining correct inflation pressures (under-inflation alone can increase fuel consumption by 3–5%)
• Driver training — a well-trained driver using proper gear selection, engine braking, and cruise control can cut fuel consumption by 10–15%

All of these are available to you when you're not drowning in a premium new truck finance repayment.

What to Look for in a Second Hand Truck When Fuel Costs Are High

Not all second hand trucks are equal when it comes to fuel economy. Here's what to prioritise when buying in a high oil price environment:

Engine Condition is Everything

A poorly maintained engine doesn't just risk breakdown — it burns significantly more fuel. A worn injector set, clogged air filter, dirty fuel system, or tired turbocharger can add 15–25% to your fuel consumption. Always have the engine independently inspected before purchase. At Boschies CC, we check this as a baseline on every unit in our yard.

Aerodynamic Configuration Matters More Than It Used To

When diesel was cheap, the fuel difference between an older cab-over design and a modern aerodynamic unit was manageable. When diesel is expensive, that aerodynamic gap translates directly into rands per kilometre. If you're running long-haul, prioritise later-model units with better cab aerodynamics.

Match the Truck Spec to the Job — Don't Over-Spec

A truck that's too large for the job it's doing burns more fuel unnecessarily. A 26-tonne truck doing the work of a 16-tonner wastes fuel on every load. Buy the right size for the job. In a high fuel cost environment, over-spec'ing is an expensive indulgence your competitors can't afford either — and the ones who right-spec will win contracts on rate.

Good Tyre Condition Directly Impacts Fuel Consumption

Check tyre condition carefully. Under-inflated, mismatched, or badly worn tyres increase rolling resistance and fuel consumption. When buying, factor in tyre replacement costs — but don't dismiss a truck with good bones just because it needs fresh rubber. That's a known, manageable cost.

The Brands That Deliver Best Value in South Africa Right Now

Parts availability, service network, and fuel efficiency make certain brands better value in South Africa's current environment:

• Mercedes Benz — exceptional parts availability, proven reliability, and strong resale value. The Axor and Actros series remain the most popular heavy trucks in South Africa for good reason.
• MAN — German engineering with excellent fuel economy on long-haul applications. Strong dealer network across Gauteng.
• Hino — excellent value in the medium and heavy rigid segments. Very well-supported nationally and known for durability in South African conditions.
• Powerstar — increasingly popular for tipper and rigid applications where cost-per-tonne-kilometre is the priority. Parts costs are competitive.
• Scania — premium efficiency on long-distance applications. The R-series in particular has proven fuel economy credentials that justify slightly higher purchase prices in high-fuel environments.

A Word on Maintenance: The One Area You Cannot Cut

Rising fuel costs can tempt operators to cut corners on maintenance to balance the books. This is the single most expensive mistake you can make.

A poorly maintained truck uses more fuel, not less. It breaks down more, costing you lost revenue and emergency repair bills that always come at the worst time. It goes out of roadworthy, exposing you to fines, impoundment, and insurance voidance. And it loses value faster, destroying your equity in the asset.

The correct response to rising operating costs is to maintain religiously and reduce capital costs — not to maintain poorly and extend the gaps between services. Buy a less expensive second hand truck if you need to reduce costs. But never reduce maintenance.

The Bottom Line

When oil is cheap, the difference between buying new and buying second hand is largely about preference and prestige. When oil is expensive, it's about survival and competitive advantage.

The operators who will come out ahead in this environment are the ones who control their capital costs tightly, right-spec their vehicles for the job, maintain them properly, and invest in driver efficiency. Buying quality second hand trucks is the single most powerful lever most South African operators have to reduce their capital exposure while staying fully operational.
