How much fuel does a Hilux use per 100km?
Most Hilux models average about 7–9 L/100km in mixed driving, with diesel variants typically around 6.5–8.0 L/100km and petrol variants around 9–11 L/100km.
That quick figure masks a range tied to engine choice, transmission, drivetrain (2WD vs 4WD), payload, terrain and driving habits. This article lays out typical consumption ranges for common Hilux configurations and explains the main factors that push fuel use up or down.
Diesel options: 2.4L and 2.8L
Diesel variants are generally the most fuel-efficient choice for highway cruising and heavy loads. The figures below reflect recent Hilux models in markets using WLTP-like testing and cover the main diesel engines and drive configurations.
- 2.4L GD-6 (turbocharged, 4-cylinder): typically about 6.5–7.5 L/100km (combined). 2WD versions tend to be near the lower end; 4WD may push toward the upper end.
- 2.8L GD-6 (turbocharged, 4-cylinder): typically about 7.0–8.5 L/100km (combined). 4WD configurations and heavier payloads often sit toward the higher end.
In practice, diesel Hiluxes deliver the best fuel economy on long highway trips with moderate payloads, while 4WD and frequent stop-start driving will lift consumption toward the top end of the range.
Petrol option: 2.7L
For markets where the Hilux is offered with a 2.7L petrol engine, fuel use is higher on average than the diesels, especially in urban driving or when the vehicle is loaded or towing.
- 2.7L petrol (4-cylinder): roughly 9.0–11.5 L/100km combined. 2WD is typically more efficient than 4WD, and city driving raises the figure compared with steady highway cruising.
Petrol versions are generally best-suited to light-duty use or where diesel availability is limited, as they sacrifice some efficiency for lower up-front cost and quieter operation at light loads.
Other factors affecting fuel consumption
There are several variables that can significantly alter fuel economy from the baseline figures above. The key ones are:
- Driving style: aggressive acceleration and high speeds spike consumption; smooth, steady driving lowers it.
- Payload and towing: carrying cargo or towing payloads increases engine load and fuel use.
- Drivetrain and terrain: 4WD with frequent mud, sand, or hills uses more fuel than steady highway cruising; flat highways are more efficient.
- Tyres and aerodynamics: correct tyre pressures improve rolling resistance; worn or oversized tyres raise consumption; roof racks or crossbars increase drag.
- Maintenance and condition: clean air filters, proper spark plugs (petrol), regular oil changes, and correct alignment help economy.
- Air conditioning and electrical loads: cabin AC and other accessories can add 0.5–2 L/100km depending on use.
In short, real-world economy can deviate from official figures, especially in city driving or with heavy loads, so owners should expect some variation around the ranges provided above.
Real-world vs official figures
Official fuel economy figures are derived from standardized tests (WLTP in many markets, EPA in the US, or similar cycles). Real-world driving often yields higher numbers, typically by a small to moderate margin for highway driving and more noticeably in urban stop-and-go conditions. You should plan for a spread that reflects your typical routes and loads.
Summary
The Hilux’s fuel consumption depends mainly on engine choice and drivetrain. Diesel variants (2.4L and 2.8L) commonly show combined figures around 6.5–8.5 L/100km, with petrol (2.7L) around 9–11.5 L/100km. Real-world numbers vary with payload, terrain, and driving style, but the general guidance is clear: diesels offer better highway efficiency; petrol is more fuel-intensive in routine driving. To optimize economy, drive smoothly, keep tyres inflated, and minimize heavy loads.
