I’ve lost some MPG's in the past few months and i can’t find out what's caused it. I’ve run injector cleaner through my car a couple times and even tried bumping up the gas grade that i put in the car (that was a pretty penny). I’ve been looking at putting a few bolt on mods on the car for fun and to see if it'll help get the MPG's back. I was getting 28 MPG and now I’m down to the 23-25 range. I do drive the car hard sometimes but even when i did that i was still getting in the 28-30 MPG
