i have a 07 automatic 2 door cobalt ls. i have had it for about a year and i love this car, especially the mileage it gets. i have been getting between 32-35 that i am very happy about but im starting to get a little greedy and im wanting some more out of it.
i have been reading these forums for a while now and have done my research, i have a clean air filter, good oil, about 40 lbs in my tires and i dont drive like im in a race every day
im wanting to know what other things i can do to my car without going "all out" like some people do.
i dont really care about performance because this car is just a every day driver work car. i just want some better mileage. if i could get closer to 40 mpg i would be content. i drive about 85% highway roads and the rest of the time i drive interstate and old country roads.
i have thought about getting a free flow exhaust, not for the sound, just for the increased mileage but do they really help that much? and do they really help that much without a better intake? if so what are some that might be worth checking out?
like i said before, im not looking to go all out, if i could get about 5 or so more MPG i would be happy (i hope thats not asking for too much). i dont want to be crunching numbers every time i drive, i just want to drive and be done with it. i figure if theres some good ways to improve mileage then it would be worth doing it. i know theres prob alot of these questions on here but i am just wanting cold hard facts that will get me the mileage, not what people have thought they might of heard from a friend
thanks alot for any input on this!
