Toyota Hilux Fuel Efficiency and Tank Capacity Through the Generations
The Toyota Hilux has been a staple in the pickup truck market for over 50 years, known for its reliability, durability, and versatility. One crucial aspect of its performance that has evolved over time is its fuel efficiency and tank capacity. This comprehensive guide explores how these factors have changed across the generations of the Toyota Hilux, providing valuable insights for both enthusiasts and potential buyers.
Understanding Fuel Efficiency and Tank Capacity
Before diving into the specifics of each generation, it’s important to understand what we mean by fuel efficiency and tank capacity:
- Fuel Efficiency: Typically measured in kilometers per liter (km/l), this metric indicates how far the vehicle can travel on a single liter of fuel.
- Fuel Tank Capacity: This refers to the maximum amount of fuel the vehicle’s tank can hold, usually measured in liters.
These factors are crucial in determining a vehicle’s range and overall operating costs. Let’s explore how the Toyota Hilux has evolved in these aspects over its eight generations.

This generation saw the introduction of more sophisticated diesel engines, leading to improved fuel efficiency, especially in the diesel variants.
Seventh Generation (2005-2015)
The seventh generation Hilux brought significant advancements in engine technology:
- Fuel Tank Capacity: 80 liters
- Fuel Efficiency: 9-11 km/l (varies significantly by model and engine)
- Engine Options: Wide range of petrol and diesel engines, including more powerful V6 options
While the fuel efficiency range widened due to the diverse engine options, many models in this generation offered improved performance without sacrificing too much efficiency.
Eighth Generation (2015-Present)
The current generation of the Hilux represents the pinnacle of Toyota’s engineering in this line[1]:
- Fuel Tank Capacity: 80 liters
- Fuel Efficiency: 10-13 km/l (varies by model and driving conditions)
- Engine Technology: Advanced turbo-diesel and petrol engines with improved efficiency
The eighth generation Hilux maintains the large fuel tank capacity while offering improved fuel efficiency, especially in its diesel variants.
Comparative Analysis Across Generations
To better visualize the evolution of the Toyota Hilux’s fuel efficiency and tank capacity, let’s look at a comparative table:
| Generation | Years | Fuel Tank Capacity (L) | Average Fuel Efficiency (km/l) |
|---|---|---|---|

Factors Affecting Fuel Efficiency
It’s important to note that fuel efficiency can vary significantly based on several factors:
- Driving Conditions: City driving typically results in lower fuel efficiency compared to highway driving.
- Load: Carrying heavy loads or towing can significantly decrease fuel efficiency.
- Maintenance: Regular maintenance, including proper tire inflation and engine tuning, can improve fuel efficiency.
- Driving Style: Aggressive acceleration and braking can reduce fuel efficiency.
- Terrain: Hilly or mountainous terrain can lead to increased fuel consumption.
Real-World Fuel Efficiency Reports
While manufacturer-stated fuel efficiency provides a good baseline, real-world experiences can offer valuable insights. Here are some reports from Hilux owners[10]:
- A 2021 Hilux SR5 diesel owner reported achieving about 10L/100km (10 km/l) with a mix of highway and rural driving.
- Another 2021 SR5 owner reported 8.2L/100km (12.2 km/l) in town driving, with even better efficiency on motorways.
- A 1993 Hilux with a 2.8L engine reported about 10L/100km (10 km/l) in mixed driving conditions.
- A 2017 diesel SR 2.8 manual transmission owner reported around 10L/100km (10 km/l) in mixed highway/suburban driving.
