Thanked: 17,236 Times. Anomaly in fuel gauge reading in my Hyundai i20 N-Line. From what I understand, the fuel gauge in cars tend to hold on to the full mark even after a bit of fuel is consumed. It has been designed in such a way that it initially depletes slower to give the driver a false sense of better efficiency. Hyundai recalled the issue in September 2016, but it's difficult to say if owners are out-of-the-woods, or if this is just a sign of things to come. 2.0 hardly worth mentioning sAi2S.
