How to Know How Much Oil is Left in a Motorcycle?

Reading a motorcycle fuel gauge is relatively simple. If the tank is full, it will display 'F'. If it shows 'E' in the direction of the red mark, that means the fuel is low. Therefore, you must pay attention at this time and need to refuel promptly. The motorcycle fuel tank sensor is located on the left side of the tank. When you warm up the bike using the side stand, the fuel on the right side flows into the left side. As the fuel level rises, the fuel float also rises, and the sensor signal strengthens, showing more fuel on the gauge. If you use the center stand to warm up the bike vertically, the fuel level displayed at that time will be accurate. There is a fuel float inside the motorcycle tank, whose function is to transmit its position to the fuel gauge via the sensor. If there is more fuel in the tank, the float rises, providing a stronger signal to the sensor, resulting in a greater response on the fuel gauge.
I've been riding motorcycles for many years, and my daily methods for estimating fuel levels are quite straightforward. The fuel gauge on the dashboard is the most direct helper—just start the bike to see the needle position or digital display; pay attention when it drops below the red line. If the bike has a reserve fuel switch, turning it to the reserve position can give you an emergency range of 20-30 kilometers, but don’t rely on it too much, as it’s just a buffer. Mileage estimation is also useful: when the bike is new, fill up the tank and ride a distance to note how far you can go, then estimate the remaining fuel based on trip length. To prevent surprises, I make it a habit to open the fuel cap before heading out and visually check the fuel level, using a clean stick to measure the depth. Regularly check if the fuel cap is tightly sealed to avoid evaporation, especially in summer when high temperatures cause fuel to vaporize quickly, reducing the amount. These habits have helped me avoid many embarrassing roadside stalls.
Want to know how much fuel is left in your motorcycle? I usually follow a two-step approach: First, check the fuel gauge on the dashboard—you can get a clear reading after starting the engine. If the reading is too low or the gauge is broken, switch to the reserve fuel—most bikes have a switch that, when turned, can keep you going for a while longer. Another practical method is to park the bike, remove the key, open the fuel tank cap, and measure manually; use a ruler or a stick to dip vertically into the tank—the length of the wet part gives you a rough estimate of the fuel level. In daily use, I keep a small notebook in the parking shed, recording the mileage and fuel gauge position after each refill for future reference. Before long-distance rides, I always fill up the tank and carry a spare bottle of fuel for emergencies—simple, hassle-free, and effective.
