2001 was the last year for the Ranger to have the 2.5 SOHC Lima engine. The 2002 and newer models have the 2.3 DOHC Duratec engine. I'm not sure what the fuel economy ratings are for the Lima engine. The Duratec engine had a range of 20 to 26 mpg with the manual transmission, 19 to 24 with the automatic. I'm getting 23 highway in the summer an 19 with mostly local mixed driving in colder weather in a truck with an extended cab and bed cover.
