I just wanted to give you my testimony with using Auto-Rx for the first time in my 96 Geo Prizm with 174,000 miles. I purchased this car in Nov 5, 2011 with 170,000 miles. It was burning a quart of oil every 1000 miles and had a leaking rear main seal. I changed the oil and filter at 171,000 miles using Mobil 5000 dino oil. After 1000 miles into the cleaning cycle the oil got really black. I then changed the filter and ran it another 1000 miles and changed the oil again with a new filter. I am now over 1200 miles into the rinse cycle and the oil is still full and the rear main oil seal completely stop leaking! I am really a true believer and amazed at how great this product really works. Thanks Frank for inventing such a great product!
