For all engines with normal engine sludge:

These application instructions are specifically for engines experiencing sludge buildup.

Your engine’s PCV system should be serviced on a regular basis. A properly working PCV system is essential in keeping sludge from returning. Also, a faulty PCV valve can create seal leaks.


Add 2 full, 12 fluid ounce bottles of Auto-Rx® Plus, as part of a fresh oil change, with a new filter installed.


For all oils treated with Auto-Rx® Plus, drive 3,000 Miles. For Full Synthetic Oil treated with Auto-Rx® Plus, drive 4000 Miles.


Drain out the oil and install new oil and filter. Drive 3,000-4,000 miles and do new oil and filter change as you normally would. Application is finished at this point.


For vehicles with heavy or extreme engine sludge, we recommend you repeat these steps with a 2nd application of 2 full, 12 fluid ounce bottles of Auto-Rx® Plus, as part of a fresh oil change, with a new filter installed.

For those experiencing oil consumption it is recommended that you inspect the PCV valve and replace if needed. A sticky PCV valve will trap positive pressure and force oil burning, as well as promoting sludge.

This application is also useful for those that own collectable cars, whereby the vehicle is only driven 1000 to 2000 miles per year.


Important Information: It is possible that the oil filter will become full of contaminants before the end of the application. At that point the oil will flow around the filter in the bypass mode. If you do hear abnormal valve ticking or noise, change out the oil filter and proceed to the recommended mileage. If this is not possible, change the oil and filter. Auto-Rx® Plus is the only product designed to safely clean as you drive.
