I have been averaging about 30mpg in the city and about 42 mpg on the highway. I purchased this car as used with just over 40 K and even though its a great little car I noticed that the idle has become quite rough while ideling at a stop. The dealer advised that this car has sat for almost 6 months and I should use a can of injector cleaner and go for a long drive. After going for the prescribed there was some improvement but not much. I then tried using mi grade gas and that seems to have made an improvement but im not pleased with the dealer who says uh well use premium and try again. :haha: your input would be appreciated.
