ok my 07 ss sc is only getting around 19MPG in town. i am driving it slower and easier than usual. i always got around 26MPG driving around in town. is there something wrong? the only mods i have are a injen intake, gm exhaust and a 3.15" polished pulley from nate. please help

 

does it feel like it is driving differently?

 

sorry thats more then i get in town..i get like 16-17

 

damn ease up on the gas lol

 

i can not feel a difference. i am just thinking that mybe since when i use to get 26 in town that was during the spring/summer/fall and now that its winter the gas mileage took a crap. does the colder temps have an effect on it?

 

A lot of stations use a different mix for winter gas which hurts mileage, also consider if you allow your car to warm up you're burning gas without going anywhere.

 

The cold weather can have a definite impact on mileage. I notice I lose about 2 MPG during the winter. When I was still getting used to driving the car I noticed that during winter I lost about 5 or 6 MPG. I have learned now how the car likes to be driven so I cut that down to my 2 MPG loss.

 

Exactly , if you allow your car to warm up at all it starts dropping the mpg, pretty fast too i might add.

 

how old is the oil in the car. i notice when the oil gets a bit old the milage drops dramatically. i usually average about 33 34mpg now im getting 24 27mpg doing the same driving once i change my oil it goes right back up to where it should be

 

i have never gotten better than 27 mpg on the hiway and my city is roughly 18.

Hey your from braidwood i used to paintball @ challange bark in braidwood Also UTI has its anual School Drag meet @ the Byron Raceway.

 

I kinda had the same question, mine has dropped from 22 to around 19.X, i thought it was the winter, i guess it is.

 

Winter mix gas always gives shittier gas mileage. I usually lose a good 4-6 mpg in the winter.
