Saturn L-Series Real Gas Mileage: Pros
YearBody/PowertrainComment
2003 4dr Sedan 182-horsepower 3.0L V6
4-speed automatic FWD		 I am getting 22mpg around town when it is not winter and about 20mpg in winter, on the highway 26-27mpg @70mph, loaded for trips. see full Saturn L-Series review
2002 4dr Wagon 182-horsepower 3.0L V6
4-speed automatic FWD		 I get at least 20 MPG, no matter what. see full Saturn L-Series review
2000 4dr Sedan 137-horsepower 2.2L I4
4-speed automatic FWD		 Respectable: 22-24 MPG around town; 25-28 MPG mixed; 30-33 MPG hwy and long distance. see full Saturn L-Series review

YearBody/PowertrainComment
2003 4dr Sedan 182-horsepower 3.0L V6
4-speed automatic FWD		 Average 25 miles per gallon seems quite low for this size car, even if it has a six cylinder engine. see full Saturn L-Series review
2000 4dr Sedan 182-horsepower 3.0L V6
4-speed automatic FWD		 It...sucks. For a 190hp v6 I expected 23 or more. I get as low as 17 in the winter, and I max out at 25 at any time in the year all highway. With new plugs I am getting 21-22 around the suburbs, compared to 18/19 earlier. see full Saturn L-Series review
2000 4dr Wagon 182-horsepower 3.0L V6
4-speed automatic FWD		 It is way too much fun to drive this car fast, and it will use a lot of fuel if you have a lead foot. Save the high revs for special occasions, and highway mileage can be close to 30 mpg. see full Saturn L-Series review
