Review on Hy-Per Fuel Complete Gas System Cleaner By Rislone by Jim Roberts

I drive a Jeep Wrangler, & recently had the EGR valve replaced and 2 O2 sensors. My mpg at that time went to 6. mpg. in a very short time. AThe EGR valve became sticky, and I am not willing to pay a high amount again to repair it. I have low mileage, and feel this is a curse, which I must shake. hahhaI bought this and put it in as directed to do, filled up the Jeep, drove no more than about 100 miles, and.I am shocked my mpg went up from .4 to 12 mpg as of this afternoon when i checked it. I am amazed, and for the price, who can ask for anything more ?Prior to ordering this on Ebay I bought a bottle at O'Reilly's ? auto parts, and paid $12.00, aND FEEL RIPPED OFF NOW.look HOW MUCH LESS IT IS SELLING FOR ON Ebay, almost 1/2 the price I paid the "discount parts" store. haha I had already placed an order for this 1 bottle on Ebay and did not want to cancel the order. I happily have a back up bottle for the next suggested time to use it again.I read about this on one of thee Jeep forums, by an individual, & then went to the site who makes this product. I WILL TELL U ONE THING, IT IS POWERFUL MAGIC IN A BOTTLE, I KID U NOT. Recommend ? Heck yea, & u r fooloish if u do not try it if you want to clean up your auto's engine.
