How have you improved your fuel economy?

[SloBalt_L61]

You're not doing it in Beckley.

Sorry.

Maybe on some of the downhill trips

I've driven all around that area, and the only way you will get 40 mpg for a whole tank of gas is in an XFE, and drive on flat ground.

Not around Beckley WV

I get 40+ (2.2 XFE) but I live in Texas it's all flat and it's all highway miles

The #1 way to increase fuel economy (assuming you've kept up maintenance) is to reduce rotating weight. On cobalts this mostly means lighter wheels and tires. On trucks and it's axles and drive shafts... And don't carry around a bunch of junk in your car. Ditch the tool box get onstar or AAA XFE's don't have spare tires or jacks for this reason.

You can look at ultra low rolling resistance tires ( the trick is they're lightweight) but the performance is total crap. Great gas mileage but a nightmare on wet roads.

well, in the trunk, i got alot of stuff. a full size spare tire, a toolbox, a foldable dolly (it called magna cart but its basically a small dolly) and my backpack with all my text books and such. i make 30 mpg and im stock

The MPG difference between auto and manual is almost negligible. Auto transmissions have come a long way since the 60s. They get about the same now.

I agree that the automatics have come a long way but when you are talking about overall weight factor in increasing gas mileage manual transmission is still the way to go. Manual transmission for the cobalt is still about 100lbs lighter than the automatic.

 

[cobalt123]

its debatable on that point. weight versus perfect shifting.

ya ... oil and air filter ... tire PSI .. should go without saying . the best MPG saver is a ecotec sticker .. i heard a chevycobaltforum.com sticker works better but cant find one ....

i have a aem cold air intake and just a weld on ebay muffler and im getting about 24.4 average mpg even though i drive alot of highway miles

what can i do to improve this because b4 intake and muffler i was getn 28-30+ mpg

 

[BankDude]

tune to actually have your engine run efficiently with those mods.

my gas mileage before mods - 36mpg

gas mileage with bolt ons + tune - 33mpg

gas mileage now with boost - 22 mpg

Fuel Economy Improvement

Some suggestions:
check out the ecomodder.com website for general ideas.
consider using tufoil (tufoil.com)
If your engine has lots of miles on it, make sure its clean inside (seafoam, auto-rx for examples)
For something completely different: rvsmaster.com
Best of luck!
