What is the exact fuel consumption of Isuzu 4bd2 tc 3.9l and how to calibrate the exact comsuption?

The Isuzu 4BD2-TC engine has an approximate fuel consumption of around 8 to 12 liters per 100 kilometers, depending on load and driving conditions. To calibrate the exact fuel consumption, you can measure the fuel used over a specific distance by filling the tank, recording the starting odometer reading, driving a known distance, and then refilling the tank to see how much fuel was consumed. This data can then be used to calculate the fuel efficiency more accurately. Additionally, using a fuel flow meter can provide precise real-time consumption data.
