Understanding the Toyota Hilux 2.4 GD-6 Engine
The Hilux 2.4 GD-6 is powered by a robust and efficient 2.4-litre four-cylinder turbodiesel engine. This 2GD-FTV unit delivers 110kW of power and 400Nm of torque, paired to either a 6-speed manual or automatic transmission[3][5].
- Common across the Hilux range, this engine balances pulling power and frugality, making it ideal for mixed-use drivers.
- Features such as a selectable 4×4 system and 2,750kg towing capacity add to versatility without drastically increasing fuel thirst[3].
For a full technical rundown, see Toyota’s official Hilux technical specifications (PDF).
Official Fuel Consumption: Manufacturer Claims
Toyota advertises a combined consumption figure of 7.3 L/100km for the 2.4 GD-6, though numbers vary slightly by model and spec.
- Manual models: 7.3–8.0 L/100km (as per WLTP testing)[5].
- Automatic models: Slightly higher, but still competitive for the class.
- Tank capacity: 80 litres, ideal for long-distance touring.
These numbers provide a benchmark but don’t always reflect South African driving realities, where traffic, altitude, and road conditions play a role.

Real-World Fuel Consumption Data
Independent tests and user reports consistently find actual fuel consumption is usually higher than official figures, especially in urban or mixed-use scenarios.
- AutoTrader’s review: Averaged 8.7 L/100km over a week of mixed driving—very close to the typical results for a bakkie in this category[3].
- Long-term user data: Fuelly.com shows averages between 26–31 MPG, translating to 8–9 L/100km or slightly better in optimal (mostly highway) conditions[1].
- Highway driving: Closer to advertised specs (7.5–8 L/100km).
- City or heavy load: Figures can rise to 9–10 L/100km or more, especially with frequent stopping or towing.
Summary Table: Claimed vs. Real-World Consumption
| Driving Condition | Claimed (L/100km) | Real-World (L/100km) |
|---|---|---|
| Highway | 7.3 – 7.5 | 7.5 – 8.0 |
| Mixed/Urban | 7.9 – 8.7 | 8.0 – 9.0 |
| City/Towing | Up to 9.0 | 9.0 – 10+ |
Real-world data shows the Hilux 2.4 GD-6 is still one of the more economical diesel double cabs available locally.
What Impacts Your Hilux’s Diesel Usage?
Actual consumption depends on a range of factors, many of which you can control.
- Load carried: Heavier cargo or towing increases consumption.
- Driving style: Aggressive acceleration, high speeds, or short trips raise diesel use.
- Tyre pressure: Under-inflated tyres create more rolling resistance.
- Terrain: Off-road, sand, or hilly conditions are less efficient than flat highways.
- Service and maintenance: Clean filters and regular maintenance keep the engine running efficiently.

Practical driving and preventive care go a long way in keeping costs down.
Frequently Asked Questions
How far can a Hilux 2.4 GD-6 go on a full tank?
With an 80L tank and typical real-world consumption (8.5 L/100km), expect a range of about 900–950km before refuelling.
Does the manual gearbox use less fuel than the automatic?
Generally, yes—the manual is usually slightly more efficient, but the gap is narrowing with modern automatics.
How does load affect Hilux fuel consumption?
Carrying heavy loads or towing can add 1–2 L/100km to your average consumption, depending on weight and road conditions.
Is the Hilux 2.4 GD-6 more efficient than the 2.8 GD-6?
Yes, the 2.4 GD-6 is tuned for efficiency, offering better economy than the more powerful 2.8 GD-6, which prioritises torque and towing.
Are there official consumption figures for different Hilux body styles?
Yes—single, extra, and double cabs have marginally different figures, but all hover around 7.5–8.5 L/100km in mixed real-world use[5].
Which driving habits waste the most fuel in a Hilux?
Hard acceleration, high cruising speeds, aggressive braking, and extensive city driving all increase diesel use notably.
