How Auto-Rx® Works

Auto-Rx® cleans engine internals, transmissions, power steering, and differentials and seals leaks, and also takes care of sludge/heavy oil burning. If your engine or transmission needs internal cleaning or you need to stop a leak, you have come to the right place. WE ARE THE EXPERTS!
Auto-Rx® is a clean-as-you-drive product. Auto-Rx® is added to the host motor oil and slowly dissolves contaminants from ring packs, cam lobes, and other high-friction areas.
Slow methodical cleaning is the desired cleaning mode, unlike old solvent technology that can chunk off contamination deposits (dangerous), and severely impact polymer seal materials. Auto-Rx® is compatible with all lubricating oils, "dino" (conventional), Group III, semi-synthetic, and full synthetics and does not alter your host oil in any way. We urge customers to use conventional or Group III oil for best results during rinse mode.
Auto-Rx® is made up of three ester groups. The lanolin ester is the main cleaning agent. Its function is to impregnate the surface of varnish and cooked up deposits. The second is an aliphatic ester. Its function is to provide for better film forming of the host oil, eliminating the potential of dry spots in the oiling system, during the cleaning process. This component is also very resistant to oxidation and is a supplement to the host oil while the contamination is being removed and deposited to the filtration media. The last ester is a biodegradable, polyol ester, which provides extra, extreme pressure capability to the host oil. Utilizing heat, pressure, and flow generated within the oiling system, Auto-Rx® safely and effectively dissolves deposits. Deposits form slowly over time; they should be cleaned slowly and methodically, as well.
The ester combination provides polarity to the host oil, giving the lubricant an attraction to metal surfaces, reclaiming these surfaces from the contamination. Lubricating oils perform well in clean working conditions. Lubricating oils can either lubricate or clean. They cannot do both well. Detergents in motor oils are added to try and maintain a clean system. They do little to nothing on deposits that have already formed.
