my cobat has 500 miles and i only see 23.5 mpg what did you guys think and what's you cobalts mpg??????

 

Stay out of boost padawan.

 

depends how heavy of a foot you have lol. i get between 23 and 26 usually, 70/30 city/highway. as of late its been all city and around 24-25mpg.

edit: didnt realize this was in LNF tech, i have a 2.2 just for reference

 

28.5 with city/highway driving mixed.

 

was getting 35 cruising at 50ish

26 mpg in mostly stop and go traffic w/ ~55 top speed

I think the minimum I would get w/o beating it horribly each time would be 25mpg

 

I am averaging 25mpg with the auto HHR SS but I get around 35 on the highway with the cruise on.

 

right now it is at 23.8

 

25.5 City getting on it. Over 35 on Highway

 

50mpg when im not boosting and barely tapping on the gas but when boosting i see 18mpg

 

^^^lol that's a 32mpg difference

 

26mpg in town... never on highway

i have 900miles

 

24.3

 

yea it is....

 

reset your mpg gauge every now and then to get a more accurate reading

 

cobalt gas mileage thread #20. You are the winner!!!

 

i average 31 my best 37 with ss/sc stage 2 tune with cold air and 3'' exhaust as
stated before stay out of boost tou will get the best milage = no fun

 

I'm just over 1000 miles and have averaged @ 27mpg. I think if I really tried I could get around 32 mpg for a week with mixed driving.

 

My speedo reads fast and my computer mpg is always 1-3ish mpg high, I figured they were linked together, anyhow...

I recently hand checked it with some city driving, mainly highway, and 5 passes at a 1/8th mi track and i got 28. With 5 passes, I'm sure atleast one other time I jumped on it, I thought 28 was awesome.

I checked it again where I only jumped on it once or twice and I got 31. Stage 2, 2.9", exhaust, intake, HPT tuned slightly. Not bad at all if you ask me.

 

28.5

 

32 avg. with a 2.4 sport and 28 with a SS SC

 

35mpg returning from VA this weekend:




City Mileage driving out of boost:



Although I usually average about 25mpg mixed highway and more city getting into the boost.

 

26mpg city/highway.

 

25 city
30 hwy

new tranny installed

23 city
27 hwy

wtf

 

alright, here are my data points so far:

Date--------Mileage----Trip OD----Gallons In-DIC MPG---Calc MPG--Difference -Rating (1-Harsh > 10- Easy)
6/9/2008---188--------170---------7.2---------25.3--------23.6--------7.2%-------6
6/11/2008--382.8-----212.8-------7.7---------28.2--------27.6--------2.0%-------8

 

with about 80% highway and 20% city i'm at 27.5 mpg and about 650 miles on my car...however...I've heard that sometimes your fuel mileage will increase when you have put some miles on it....probably around 1,500 miles....sometimes the computer runs rich when it is brand new to make sure the engine is properly broken in....watch your fuel mileage once you get past this point and it will probably improve...

also...those guys that were saying they can get 50 mpg barely tapping the gas....i can get 99 mpg coasting....so that instantaneous mpg is irrelevent!
