“I operate a 1999 W900 Kenworth powered by a C-15 Caterpillar engine with more than 450,000 miles on it.  In using the Bonneville catalyst product, I realized a 14.3% MPG improvement from 5.59 to 6.39.  I felt an almost immediate surge in horsepower on inclines, and noticed that the engine seemed to operate smoother without the acceleration hesitation that I experienced in the past.  I did not alter my driving habits and believe I would have had better comparative results without the strong head and side winds variable on my return trip.  Also more than 25% of my baseline vehicle mileage test was with an empty trailer. ”

“I own a 2006 Chrysler 300 and have received an average of 20.9% increase in fuel economy since I started treating my gas with Bonneville Fuel Tabs. My engine is running smoother and at my last oil change, after 10,000 miles, the technician said my oil showed a lot less breakdown than he expected at 10,000 miles. The immediate savings and long term benefits are a fantastic value!”

“I operate a four rig, long haul trucking company out of the Northwest and conducted a month long comparative test on the Bonneville Fuels catalyst during the April/May 2008 timeframe.  Being a natural skeptic because of the unsubstantiated claims of other products, I was pleasantly surprised when I realized a 14.06% improvement in MPG from 5.51 to 6.28 on my rig that has more than 325,000 logged miles, which translates to an annual savings potential of more than $8,600.  Such a savings will not being ignored in the future operation of my business!”

“I own a 2003 Chevrolet Duramax 2500 HD that I use for work and personal use. As an analytical and mechanic by background and training, I started using the Bonneville Fuel tabs with low expectations and a fair amount of skepticism. After two tanks of diesel, I noticed that my engine temperature was operating almost 15 degrees lower than it had been historically, and as of this writing, my exhaust temperature are operating between 100 and 150 degrees lower. I fully expect that my emissions have been substantially reduced because there are no evidences of exhaust smoke anymore. The digital oil percentage gauge has been maintained at the same percentage as when I started using the Bonneville Fuel tabs when normally I would be changing my oil by now. While these benefits alone are significant, my fuel mileage has improved from 11 mpg to 13.2 mpg a 20% increase while even pulling around my trailer and bobcat. I will not be without the fuel tabs, Thank you Bonneville Fuels!”

"We tested the product on our trip to Zions National Park in our 2004 Scion xB. We averaged about 25.3 MPG on the way there. We added the Bonneville Fuel Tabs and followed the directions for "flashing" our computer. On the way back we averaged 28.6 MPG! We will definitely continue using it!"

“My husband bought me a 2004 Audi TT convertible a year ago for my enjoyment of the California sunshine while he traveled more on business. He also asked me to use the Bonneville Fuel Catalyst product mentioning benefits that did not mean much to me other than an increase in power. Ignoring the other benefits, I did experience more pick-up and horsepower as the beautiful countryside passsed by more quickly, but when he asked me about the improvement in MPG, I could not report and improvement. Why despite the claims? Because I transferred the savings to my foot on my California Dreaming drives, I wasted the benefit! Now that I am fully aware of the trade-offs, I have recorded an increase of slightly more than 17% over the past six months as I now do not accelerated at more than 3000 rpms. I am amazed at the savings since I now use the lowest octane fuel without any loss of power and know that I am contributing to better air quality.”
