Why isn't MPG applying in VinMotion for my vehicles?

MPG is calculated based on the Transmission and EPA information (including Engine size, Fuel Type). It can vary for different Trim levels. Regardless of the source - Polling, VinMotion, ASW - Trim and Transmission have to be available for the VIN-decoder to calculate MPG. The Mapping tool in VinMotion will allow users to add missing information so MPG can be calculated. NOTE: for brand-new model years, the VIN-decode software is updated with MPG data as it becomes available from the manufacturer.
