If your car has well over 100,000 miles you can get away with doing just a Clean and Rinse application, meaning you might not have to do a 2nd cleaning.
I would advise that you get a 2nd bottle of auto-rx to use as a Maintenance Dose after the initial clean and rinse. This will keep the gains you have gotten and will help with some additional cleaning.
A 12 ounce bottle of auto-rx will last 3 oil changes using 4 ounces for each oil change.
This application does not apply if you have:
1) Sludge
2) Oil Leaks
3) Oil Burning
I would advise that people use a cheap dino oil for the Clean and Rinse Phases, and when you go on the Maintenance Dose either use dino oil or a Group III synthetic since some cleaning will be going on after the Clean and Rinse Phases are over.
This is the only product that I know that will clean your engine without hurting your oil seals. This product does work if you follow the application instructions.
The Fleet Taxi Test proves that auto-rx works.
Even if you pull your valve cover off and your engine looks clean, you may still have some junk in your ring packs or other areas of your engine that you cannot see even with the valve covers off.
