I wanted to thank you for such a great product in your Lucas Fuel Treatment. I ran an impromptu experiment when I took a recent trip from Texas to PA. Starting out without Lucas running 89 Octane gas in my 2005 Chrysler minivan, I was barely getting over 19 MPG. I bought 4 bottles of Lucas and used it with every tank of gas on the way up to PA. I saw steady MPG improvement and by arrival, I had achieved a consistent 23 MPG. On the way back, we achieved between 24 and 25 MPG consistently for each tank of gas. What an impressive product. Thank you very much!

I recently replaced the fuel sending unit in my Xterra which Nissan would not cover. I just came out of the warranty by a few miles. First tank, my mileage was off by 30 to 40 miles. I pulled the battery cable to reset the ECM. I was only off by 20 to 30. I went and got some Lucas and poured it the tank. My mileage is now back where it was and the engine is smoother. This is good stuff. It blows away anything else in a bottle.
