The Isuzu KB 240 LE’s fuel consumption varies depending on driving conditions and the specific model year, but official figures from Isuzu claim a consumption of 10.5 litres per 100 km for the 2.4-litre petrol double cab 4×4[1]. However, in real-world mixed driving, automotive testers have reported figures as high as 13.5 litres per 100 km[5]. User experiences suggest that consumption typically ranges from 12 to 14 litres per 100 km, especially if driving with a heavier foot[3].
This higher fuel consumption compared to diesel variants is a well-noted characteristic of the petrol Isuzu KB 240. While it provides reliable power and is more responsive than some diesel models, diesel versions are generally recommended for their better fuel economy and overall value[1][5].
