Is the fuel-economy change based on repeated tank/trip measurements?
A repeatable measurement is more useful than a single dashboard reading.
CarFactBook Diagnostics V3
Record a result. Follow only the branch it unlocks.
Choose a symptom and exact chassis when possible. Diagnostics v3 asks one reachable observation or test-result question at a time, prunes stale branches when a result changes, and prepares a mechanic handoff from the path you actually took. It never invents a diagnosis or failed part.
