Better MPG
I have a stock 2001 XJ and I bought a big bottle of Lucas Injector cleaner, which is also an upper cylinder lube and it has vastly improved my MPG. I'm not even done with the tank of gas and my Jeep is running quieter. I have tried other injector cleaners; seafoam, stp, gunkout, etc. And none of them compare to the Lucas. I completely filled it up (past "F''.)

I'll be thinking that im getting like 20 mpg but once i get to about 3/4 tank then it divebombs to half tank. I get the same feeling of being let down every time!
