Engine Sludge Removal | Auto-Rx

Having trouble getting started? Click here to learn more about how to get started with Auto-Rx® Plus today.


Gas and diesel engines accumulate dirt and other contaminants through the air intake and internal combustion process. An engine with as little as 25,000 miles will benefit from a basic cleaning using Auto-Rx® Plus. Afterwards, continuing to use Auto-Rx® Plus will ensure your engine remains free of contaminant build-up.


Doesn’t my oil come with detergents from the manufacturer? It does but the oil from your manufacturer doesn’t contain enough detergent to clean your engine. Read our forum post for more information.

As your engine runs, it generates extreme heat. These high temperatures actually change the components of your engine oil, breaking it down into a residue that remains on every part of your engine, including non-metal parts such as seals. But residue isn’t the only thing that heat and oil can create; harmful by-products such as sludge, varnish, and sulphur also come into play, and as soon as they combine with condensation and airborne pollutants (dirt, soot, and industrial debris), contamination build-up is created.

Auto-Rx® Plus acts slowly and safely to dissolve these contaminants while maintaining the host oil chemistry. It does not affect the viscosity of the oil. It liquefies sludge, carbon, and other debris in your engine while you drive and prevents clogs in the flow of the oil. Auto-Rx®Plus uses your oil to get into every nook and cranny of your engine. Just pour Auto-Rx® Plus into the crankcase and drive your vehicle as usual!
