I bought a used 2018 Chevy Equinox, LT, front wheel drive about nine months ago. I've averaged around 25.8 miles a gallon driving in town. The last month its dropped to 20.2, then 19.7 and now 17.8. I've had it in for service and the spark plugs were changed and they put something in the fuel line to clean it out. Nothing has helped, it's getting worse. They ran a diagnostic test and everything checks out fine. It is winter now, but the drop started before it got cold. Air in the tires is fine. At a loss and can't understand this. Vehicle just turned 54,000 miles.

I would hope they looked at the engine air filter and cleaned the throttle body. i would run it by an auto parts place that advertises free code scans and see if they find something.
I will do that. Thanks for the reply.
In the northeast, come winter, they switch to a winter grade of gasoline which has less BTU s and will decrease your gas mileage. Also, do you remote start your car ? That will decrease your gas mileage to zero during that time period.
But you are seeing a huge decrease in mpg. barrios says that changing your O2 sensors can improve gas mileage, but I have never tried that. He says that they get lazy, I believe.
