First tank after tune-up. MPG posted

I got 25mpg after first tank. It is a mixture of city and highway. About 50-50. The O2 and other sensors weren't replaced until about 50% of gas tank. So, I will post back after next tank full. I put some engine cleaner in and changed oil to Rotella 5/40. I noticed more power. Must have been dirty!

I am hoping to see 30mpg with my heavy foot. I have seen 38mpg posted. But, that could be with someone who has a light foot and never see anything over 3k on the tach.

I was wrong! It got 20mpg!! WTF? I do drive it hard. No used to the difference in power between cars, so I am on the pedal a lot. but, geez. Around town 20mpg? No grandma driving, just drive it. No racing either. Can someone post what your getting? I did use a calculator too.
