I'm very excited I finally finished my rinse phase on my 2000 Grand Marquis. I changed my oil yesterday using Mobil 1 5W30 full synthetic and added the 3 oz. maintenance dose. The results are already noticable! I probably can't attribute all of the improvement to Auto-RX, since until yesterday I used the Motocraft synthetic blend and I also replaced the PCV valve.
But I did definitely notice an improvement in gas mileage already after 100 miles into my first maintenance dose! In the past, aggressive city driving would warrant about 17MPG, and easy going city driving would get me about 20MPG. Yesterday after I changed my oil I was doing a mix of both and already got up to 22MPG. I can't wait to take it out on the highway today!
Thanks for the great product, Frank!

Thank you for purchasing Auto-Rx. I had a 92 Grand Marquis 4.6 engine and after the cleaning and rinse phase my MPG went from 18 to 21, I also had a rear main seal leak and after 2 oil changes using Dino oil the leak stopped. The maintenance dose will keep your engine clean and running.
Well I just did some highway traveling today. After about 120 miles traveled on the highway, I was getting an average of 28MPG. I'd say that's really impressive for a big car. Half of the traveling was with someone in the passenger seat. And most of it was done with the A/C on. During the 30 mile stretch back home this evening it was cool outside so I just used the vents.
Extremely pleased with this product!

My wifes Jetta saw a 7 mpg increase after doing a treatment...now i did do a tune up before and after researching the paper work my father in law gave me he did do a tune up about 30 K ago. I think Rx helped alot....thats why i ordered 12 bottles, should last me 10 years or so.
I'm about ready to order a few more bottles too. And I used some in my girlfriend's car, and my family's other cars so I'm going to buying in bulk like yourself. Well worth the money!
