My 2017 Ford Escape (80k miles) has been burning through gas like crazy off and on for the past couple of months. For example, today I filled up the tank, drove just 5.5 miles, and my Distance to Empty (DTE) dropped from 236 to 198 miles.
It doesn’t matter if the car is warmed up, if I’m using heat, or if I’m driving on the highway or in the city. I’ve been driving it normally, but nothing seems to make a difference.
I’ve run tests, but nothing is showing up. Has anyone else had this problem or knows what might be causing it? I’m tired of wasting money on gas.
The DTE calculation isn’t always accurate. Resetting the trip or looking at your average fuel economy is more reliable. If you’re getting less than 20mpg, it might be your turbo going out.

Both my fuel gauge and DTE drop fast, so it’s not just a calculation issue. Could it be something with the Ecoboost? It doesn’t always happen, which makes it harder to figure out.

Even though spark plugs are rated for 100k miles, I’d change them now to see if it helps. Sometimes they don’t last that long.
As for the turbo, if it’s starting to fail, it can hurt your MPG a lot. The engine relies on it, so if it’s not working well, the engine has to work harder and burn more gas. My turbo is on its last leg, and I only get an underboost code in specific situations (like high altitude and accelerating uphill). Otherwise, the only sign is bad gas mileage—I’m down to 19mpg.
