Ask a real question and watch which readings the answer is built from. Then scrub a recorded drive, compare adapter mode against GPS-only, and see a fault code explained without the jargon.
Why did my fuel economy drop to 15.1 mpg today?
Today’s drive was short — 3.3 miles — and started at 21°F. The engine spent most of it running rich while it warmed up, which is exactly when mileage looks worst. Nothing in your fuel or oxygen sensor readings suggests a fault. This is normal for a cold short trip.
