How to Use Auto-Rx Plus with Synthetic PAO Motor Oil
If you choose to run Auto-Rx in a full-synthetic PAO-base oil (such as Mobil 1), you must increase the cleaning phase and rinse mileage to 4,000 miles. PAO-base oils do not accept additives readily and need coupling esters to hold the additive package in suspension. These esters compete for the same space on metal surfaces as do the cleaning esters of Auto-Rx, which slows down the cleaning action and takes longer. Also, PAO oils are not a good choice in the rinse phase because those coupling esters make the oil cling to metal. This interferes with Auto-Rx being able to rinse the metal surfaces fully. We cannot guarantee the results of your cleaning application if you use these oils, because they do not work the same as conventional oils. All engines, including turbos, work well using conventional oil with Auto-Rx Plus. Please follow instructions for sludge removal when using Auto-Rx Plus. Saves money and your time.

Auto-Rx® Plus is not a solvent, a friction reducer, an oil enhancer, or any other magic potion — although these may be side benefits. Auto-Rx® Plus is added separately. It does not change the properties of your motor oil or transmission fluid. It is safe chemistry applied on a periodic basis as part of a common-sense extended protection plan. If you have ever taken apart an engine or other equipment, you know what dirty oil can do to bearings and other surfaces. Those who have used Auto-Rx® Plus no longer see the results of that dirty oil. Why should you?

Auto-Rx® Plus ecologically removes sludge, dirt, carbon, and other contaminants from engines, turbochargers, piston rings, transmissions, power steering, differentials, and motorcycle engines.

We safely rejuvenate your automobile’s seals, by reducing and/or eliminating oil leaks.
