Mid 20'* at least in combined driving.

I get 24-26 average in winter with my 88 Lesabre with 2.97 axle. That'* on my 40 miles commute, 70+MPH with stop lights. Even city, I've never gotten worse then around 22 MPG. A lot better then my 97 L67, but short of our 98 L36.

Been averaging about 17 lately... thanks, GX3 and winter
