I just started keeping a fuel consumption log myself. Why? Because I noticed my Miles per Gallon are extremely inconsistent. I'm usually pretty consistent with my riding style which is not very aggressive, yet I feel that my fuel consumption dose not match my riding consistency. I hope by collecting this data I'll be able to tell if there might be an intermittent problem either with fuel delivery or ignition problem. My fuel consumption varies from 32 MPG to 52 MPG. It just seems to me that it is radically inconsistent.
