Be carefull, U can do more harm than good! This stuff may work on an understressed 400CI ford or 396 chevy with NO post catalysis but NOT on a modern auto.

Completely false!
I use Lucas UCL in every tank and I get 7% higher MPG, and no issues with the catalyst, nor valves, nor anything. I also pour Chevron Techron concentrate bottle in tank every 5,000 miles.
I've used Lucas in several other cars in the past 10 years and NEVER any cat problems, nor deposit problems. And in fact the valves on my 1993 Honda Civic are like new clean!
