Attn: Nick, I wanted to tell you the whole story about my experience with your product because it may help others….I have a 35 foot 1999 Class A Chev. motor home with 454 engine, which is not exactly a gas sipper. I've had many other RV's in the past and always enjoyed adding many unique products to them (which I do myself)…..I have a friend who also has an RV and I have always jokingly competed with him regarding what we have installed last. When he called and said he installed your AquaTune system, I was really intrigued. By the way, he also got extremely high results and his RV is two years newer than mine…..So, I called and ordered one of your systems…..All this took place about three weeks before I left on a planned trip of at least six weeks and 6,000 to 7,000 miles….I did find an extra large water container that I've been using…..Well, I finally took off on my trip that lasted over six weeks and we traveled over 6,500 miles. Many of the miles were in mountainous areas….The results were dramatic in power that showed up going over hills and accelerating. I commented many times to my wife that I am going uphill and I'm still in overdrive! It didn't shift down as it did before the system was installed!......Before this trip I had used the RV for three trips of less than 500 miles each. When I called you the end of July, I told you that my mpg had increased from 6mpg to 8.5mpg!...On this trip it varied a little more, but then, I was pulling a full-size Jeep and I also logged 89 hours on my gasoline generator, which draws gasoline from my general fuel tank. So, logging in on this trip at an average of 7.738 mpg and the fantastic performance of the engine were good enough for me!......One more incident that was quite shocking to me was when I had an oil change half-way through the trip. When they pulled the pan with the drained oil out we were all shocked at how black the oil was! I commented that I had this water injection system installed and it was suppose to clean out the engine as well. I believe it, because when I arrived home I checked my oil again and it is still almost as clean as when it was installed….In conclusion, I thank you for the excellent support as well as a great system!!
