Hi I was wondering about this for a while now, I know you guys would know, thx!
I think it depends on where you're driving. Here in Wisc we don't have much in the way of hills. I get around 34 mpg driving from Milwaukee to Lacrosse using the cruise.no, it kills your MPG

If you read through some of these mpg threads it has been explained in detail
There you go. perfect.no, it kills your MPG
You prolly would have gotten better than that without the cruise control.I think it depends on where you're driving. Here in Wisc we don't have much in the way of hills. I get around 34 mpg driving from Milwaukee to Lacrosse using the cruise.
We just took a driving trip to Dallas, very different terrain in Missouri & parts of Illinois. Still 33 plus mpg. The way down averaged 63 mph for 1050 miles.
I have a 2010 Cobalt with auto transmission.
Cruise control is never the best answer unless.... See Belowif ur driving straight on the thruway with no hills its better for mpg to have cruise on. as soon as u see a hill or w/e take it off.
^^^ this.If your the type who when driving your speed slowly creeps up the cruise control can help you by keeping your speed where you set it.
Otherwise you can get better mpg by driving without it.
I really don't see how going a constant speed on non-hilly roads is gonna hurt your gas milage. I use it 90% of the time, drive 310 + miles a week, fill up once a week, & average 30 mpg. I also have the 2.4 Sport......
Yes, I fill up @ the quarter tank mark, or usually just under(50 - 60 miles left).........sorry if you are averaging 310 miles in a week and filling up at that, you are NOT getting 30 mpg, more like 25.8 mpg... the only way you will see 30 mpg is if you are doing 360 every tank full. you know, 12 gallons in a tank, times 30 mpg equals 360 Miles. You are not filling up or using your entire tank if you are filling up at 310 miles, you would still have just about 2 gallons left if you're getting 30 mpg, then that is another 60 Miles...
Yep. Those of us with boost gauges can see the fluxuation in throttle that occur while using cruise. When I'm going down a hill, the engine likes to run in high vac, but if I'm going up hill, often times the cruise will put the car into boost to maintain speed.Cruise control only keeps the speed of the car constant. It does nothing to keep the fuel flow constant. That is the limitation of cruise control.
30 is good for an Auto, I get 28.5 in my auto, mostly because of the stop and go traffic. Though When I reset my MPG average meter and after a day or two I was in my garage and the MPG average went down considerable because I have a 32 MPG average for those two days and I watched it go to 30 while I was plugging in my Ipod, I don't think our cars know when we are stoped at a light or on the highway and It takes out no outliers. Just some food for thought.Will knows his stuff. I never question what he says about MPG info.
you just proved in your own post that cruise kills MPG. 30 mpg average is bad for a cobalt. I get 35 without even trying to get good mpg. (also I do not even have cruise control in my car)
It wont. Cruise is great if you live in Kansas, not so good in West Virginia.I really don't see how going a constant speed on non-hilly roads is gonna hurt your gas milage. I use it 90% of the time, drive 310 + miles a week, fill up once a week, & average 30 mpg. I also have the 2.4 Sport......
