Cadillac STS Real Gas Mileage: Cons
YearBody/PowertrainComment
2006 4dr Sedan 320-horsepower 4.6L V8
5-speed shiftable automatic RWD		 16 city/21 highway. Buy it only if you can afford it with out complaining. see full Cadillac STS review
2005 4dr Sedan 320-horsepower 4.6L V8
5-speed shiftable automatic AWD		 This car is thirsty. I live in flat country and I get 15 mpg with 80% highway traffic. I only get 19 mpg on trips. It probably needs a 6th speed overdive for the highway. see full Cadillac STS review
 

What Our Members Are Saying about the Real Gas Mileage of the Saturn S-Series

Saturn S-Series Real Gas Mileage: Pros
YearBody/PowertrainComment
2002 4dr Sedan 100-horsepower 1.9L I4
5-speed manual FWD		 With the SOHC engine and MT,heavy AC,I get 35-38 MPG cruising at about 70MPH 10% ethanol gas.Gas without ethanol gives about 10% better fuel economy but is not available in most places near me.It makes no sense to add 10% ETOH if mpg drops 10% see full Saturn S-Series review
2002 4dr Sedan 100-horsepower 1.9L I4
4-speed automatic FWD		 The car gets good mileage, close to 35 mpg on the highway. I need to replace the intake manifold gasket - that will probably increase the mileage by a few. see full Saturn S-Series review
