This product worked great. The larger bottle is handy. The price was much less per dose than other major brands.

Rated 5 out of 5 by RacerRon Wonderful Product
First thing, Lucas Oil Co, is a great American company out of Indiana. Sponsoring every type of racing you can thing of. Of all there products, the most used by me is the Fuel Treatment-Upper Cyl Lube. I add 2 oz.'s of it to each of my four vehicles after a fill up. Our two daughters live over in the Southbay, when they visit I add it to their cars also. I may also use injector cleaners. octane boosters and fuel system treatments at times, but is great that Lucas provides a product for upper cylinder lubrication, this treatment elimates nightmares concerning engine problems. It probably also lubes the in tank fuel pumps.
