I've been getting only 18.3 mpg this past month, usually it would show 20.5-21.9 on my dash and recently its dropped down to the lower 18's. Is something wrong or am I suppose to be getting this low mpg?

have you changed your driving style, in DS mode? also, you have new wheels on now right? from 18" to 20's....wonder if that might be effecting your mpg's

also, how many miles on your ride? when was your last service? what was done?


I get about 19-20 on the streets and 25-28 on the hwy


when I had my jb+ it was less

yeah I have 20's on now, my driving style is pretty much the same I don't gun it, and my vehicle has around 28k miles on it. Is 18mpg normal though or you think something may be going bad?

18.3 sound hella good to me.

I avg about 17.2 on my V8. Does that sound about right for the v8's? I went from oem 18's staggered to oem 19's staggered.

I've managed to bump my MPG to 22.7
MPG, driving like the biggest grandma, and using only cruise control. That's right, 22.7MPG out of 430HP
