My wifes fuel gauge has been reading about a 1/4 to a 1/2 tank off on fill ups. So on a recent 1200 mile trip I packed the bottle, & after the third fill up the gauge was functioning like new. I will keep that in the mix! We had a 92 Jeep Cherokee that we used only as a winter car. When I brought it out of my back garage in the spring two years ago, it had a major leak out of the front trans seal. So I did a fluid & fliter change & added the Lucas Transmission additive. Started it up & to my amazement no leak at all. Also used it in the rear diff to stop an axle seal leak. Still no keaks two years later. My sister-in-law drives the car everyday!

I am sold on Lucas products!
