I average 22-23 in 95% city driving. When I do get on the freeway I get 30 mpg easy.

I get about 19-20 mpg but due for a spark plug change in a few thousand miles so hoping that will help a bit

19 is normal.
I drive mostly city, average 20mpg with ECT on normal mode.
I don't know how people get 30+ on the highway even EPA states that its 19 city and 26 highway. And thats pretty much what i am getting.

I average 21/25 with 380 to a tank. Only surpassed 400 a couple times. ECT Snow helps in traffic, but as stated above there are a couple threads on this. (Quite frankly I don't mind repeating myself as long as the previous threads fail to provide a definitive answer within the first two pages.)

I get about 23 mpg with 50/50 city/highway driving, but can get 30-31 mpg going 65 mph. I used to get around 27 mpg when I took toll roads and drove 70/75 mph, 95% highway.

I usually get 18-19 MPG and I have a mix of city and highway driving.
