How to Calculate the Fuel Consumption per 100 Kilometers for a Motorcycle?

The owner should first record the odometer reading L1 when the fuel level is high and the engine cuts off due to low fuel. Then, note down the amount of fuel YL added during refueling. When the fuel is again used up to the high fuel level cutoff point, record the current odometer reading L2. Subtract L1 from L2 to get the distance traveled, then divide this by Y to obtain the number of kilometers the motorcycle can travel per liter of fuel in actual driving conditions.
I usually ride a motorcycle for commuting and love calculating this! The most accurate method is: First, fill up the tank until the pump clicks off, and note down the current mileage. Ride about 100 kilometers (less in the city with many traffic lights, more on the highway), then go back to the same pump and fill up again. Divide the amount of fuel added the second time by the kilometers ridden, then multiply by 100, and you get the actual fuel consumption per 100 kilometers. Remember to avoid gas stations on slopes and insert the nozzle deeper to reduce errors. Last month, I used this method to test my 150cc scooter, and it actually consumed 3.2 liters in the city, which is 0.5 liters higher than the official data!
After riding for three years, I found that fuel consumption is greatly influenced by driving habits. To calculate accurately, you can't just rely on single data points; it's best to measure three times consecutively and take the average. My method is to fill up the tank, reset the trip odometer, and then check how many kilometers I've driven at the next refueling. Divide the amount of fuel added by the kilometers driven and multiply by 100. The key is to record the exact amount of fuel added each time. 95-octane gasoline has a slightly higher density than 92-octane, and mixing them can affect the calculation results. Last time, driving on mountainous roads with many uphill sections, the fuel consumption per 100 kilometers was 0.8 liters higher than on flat roads.
