As of Nov 2020, Vehicle Fuel Tracker is no more
Vehicle Fuel Tracker was the primary interface to the Vehicle Management API. This site houses a collection of features, allowing users to track the Total Cost of Ownership (TCO) for their vehicles, for free! It provided an API allowing easy integration of statistics into websites and apps, along with various tips on improving fuel economy.
However, all good things must come to an end, and unfortunately it simply wasn't financially viable to keep the site running.
