A vehicle control system includes a computer and logic executable by the computer. The logic is configured to read an odometer value from a storage system. The odometer value corresponds to an accrued mileage obtained from an odometer. The accrued mileage is determined at a beginning of a current driving event. The logic is also configured to read an odometer value for the vehicle from another storage system. The odometer value from the other storage system corresponds to an accrued mileage obtained from the storage system at the beginning of a driving event that precedes the current driving event. The logic is further configured to compare the odometer value from the storage system to the odometer value from the other storage system and calculate a reduction value from the difference, upon determining the odometer value from the other storage system is greater than the odometer value from the storage system.
