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!

7% higher than what?

For the way I drive, and the city/hwy mix:

42 MPG + 7% = 42 + 3 = 45 MPG, when I use Lucas UCL in every tank of gas.
