The Isuzu KB300 has an official combined fuel consumption figure of approximately 7.7–7.9 L/100 km (about 12.7–12.9 km/L) according to manufacturer specifications and regulatory testing[2][1][5]. However, real-world usage reports from owners and independent reviewers frequently note a higher consumption, typically ranging between 9.5–10.5 L/100 km (about 9.5–10.5 km/L) depending on driving habits, conditions, and whether the model uses automatic or manual transmission[3][4][5].
Some additional context based on user experience:
- While some drivers have managed figures close to the official rating, many report consumption closer to 10 L/100 km in mixed real-world conditions[4][3].
- Factors such as towing, off-roading, urban stop-start driving, and mechanical issues (for example, faulty injectors or fuel pumps) can worsen fuel consumption[1].
- Routine checks—such as monitoring injectors and the suction control valve—are recommended if consumption is unusually high[1].
In summary, while the Isuzu KB300 is marketed for its relatively efficient diesel consumption, consumers should expect actual usage to be slightly higher than the manufacturer’s official figures in daily driving scenarios[3][4][5].
