I've been using the AR6200 with nearly every tankful of gas for about 15 months now in an '04 Suburban with a 5.3 Vortec. We bought the car about 6 years ago with 100,000 on it and it ran very well at that time. Then it slowly seemed to lose power, acceleration, etc. The car now has over 200,000 miles on it, and with this recent fuel treatment it runs better than it did when we bought it! The acceleration when merging onto a highway, etc, still surprises me. I used to the think the engine was underpowered for this heavy car - and with poor performance it was. Not the case anymore, that engine just needs to be allowed to run well! I also installed the 9100 friction modifier with an oil change 15 months ago, but it was only with one oil change as I used up this product in some other machines. I don't know whether it's the fuel conditioner or the friction modifier or a combination of both, but this engine just runs great - at 200,000 miles!
Love it. put in all my Gas engines. when the Wife fill up the Jeep and forgets to tell me and I get in to drive it I can tell as soon as I pull onto the freeway and no power. And when I put it in all my lawn equipment and I start it up in the spring they start right up.
Very happy with my purchase. My vehicle runs great.
The fact that it helps with reducing the water condensation in the gas tank and makes the fuel burn completely was my trigger of interest cause living in a state that it's cold for 9 months and then learning from the Jay Leno video about the fuel treatment, I was sold.
Great results for my diesel no Improvement V8
