Ambler's Texaco Gas Station, also known as Becker's Marathon Gas Station, is a historic filling station located at the intersection of Old U.S. Route 66 and Illinois Route 17 in the village of Dwight, Illinois, United States. The station has been identified as the longest operating gas station along Route 66; it dispensed fuel for 66 continuous years until 1999. The station is a good example of a domestic style gas station and derives its most common names from ownership stints by two different men. North of the station is an extant outbuilding that once operated as a commercial icehouse. Ambler's was the subject of major restoration work from 2005 to 2007, and reopened as a Route 66 visitor center in May 2007. It was added to the U.S. National Register of Historic Places in 2001.
