Dear all,

Do you use the term "low gas mileage" meaning that a car consumes a lot of petrol per one gallon?

    No. In the UK it’s petrol, not gas, and we would describe a car as having low petrol consumption. I imagine the same, but with “gas”, would apply in AE.*

    But you can use the term “mileage per gallon” (or litre).

    *But as the replies below show, this is not the case!

    Or "poor fuel economy".

    Fuel economy in automobiles - Wikipedia

    The fuel economy of an automobile relates distance traveled by a vehicle and the amount of fuel consumed. Consumption can be expressed in terms of volume of fuel to travel a distance, or the distance travelled per unit volume of fuel consumed.

    You might hear someone in the U.S. say something like, "I really like my car but it doesn't get very good gas mileage."

    Often the "gas" in "gas mileage" is left off if the context is known. See the example I made up below. (I made up the conversation, the mpg cited is accurate.)

    Mike: What's your gas mileage on your new Toyota Avalon?

    Pete: It's a hybrid so I'm getting 43 miles per gallon.

    Mike: Wow. That is really good mileage. Is it city, or highway?

    Pete: It's 43 mpg city and 43 mpg highway according to the EPA, so the combined is 43 mpg.

    Mike: Wow. That's really good mileage for a large car.
