5.0 out of 5 stars Once A Skeptic, Now A Believer.

I did a rather controlled test with my 1995 Lexus LS400 using Xtreme Fuel treatment. I recorded my driving habits and fill-up statistics on a spread sheet for three months before adding this product to my gas. I used the same brand and grade of gas, from the same station exclusively. Though I annoyed my wife with this strict behavior, I took the same routes to work, church and other destinations (at consistent driving speeds). Then I consistently added the recommended amount of product with each fill-up and repeated the driving habits while documenting the miles between fill-ups. Again, I did the same thing for three months with the product in the tank. In the end, with Xtreme Fuel, I was averaging two extra days of driving between fill-ups! In other words, before I used this product I would fill-up on Sunday evening and could make it through the following Sunday (seven days) before the fuel light came on. However, a the end of three months of using the additive, I could do the Sunday fill-up and drive for a week, go past Sunday, into Tuesday (nine days) before the fuel light came on! Do the math. That’s nearly 3 1/2 months of extra driving days from the same brand of gas!
