unprobed
Gas mileage checker: authoritative city/highway/combined MPG for any US light-duty vehicle model year 1984 or newer, with fuel type, greenhouse-gas score, and estimated annual fuel spend. VIN input is decoded automatically; fuzzy model matching bridges naming differences. For automotive and budgeting agents.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
