I am writing to you about my experiences using auto rx. In the last couple of years, I have ordered 6 bottles for my cars. Car # 1 is a 89 dodge with the 3.0, with 185,000 mi. It was using 1 quart every 400 mi., and blowing a ton of smoke out the back. After the 1st treatment, it stopped almost all the smoke, and was using 1 quart every 850 mi, that was great. Car # 2 is a 97 dodge caravan with tranny issues. Every time it got cold, it wouldn't shift very well, it would shift crappy after it was warm. So in went 6 oz of rx, drove it the 1000 mi., man what a differance! Shifting was great, and after I gave it a full flush, it worked even better, like new.

Car # 3 is a 2001 chevy 1500,v6, with 125,000, I ran 2 bottles thru it, and the mileage went from 17 to 21 mpg., all hand calc.amazing! Car # 4 is a 98 1 ton chevy cube van, with a 10 ft box, we use for trade shows around the country. Before treatment 11 mpg, and 1 qt. every 3000. After 1st clean and rinse, 13.5 mpg, and 1/2 qt every 3000, super; my dad thinks I'm a genius. Last bottle went in 2002 dodge stratus with 53,000 mi. no issues just peace of mind. By the way Frank, I just ordered 5 more bottles. Thanks for your super product.
