Gas & Diesel Engine Cleaning with Auto-Rx® Plus

Did you know that 95% of vehicle problems are caused by the build-up of contaminants like carbon, sludge, dirt, and third-party abrasives in your engine? These contaminants, combined with engine oil and heat from your engine, create uneven hot spots and extremely harmful by-products. The contamination process has already begun in the first 25,000 miles of your engine’s life.

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! Auto-Rx® Plus works as you drive.

Before purchasing, please refer to the INSTRUCTIONS. For even more ways this amazing product works, please visit our pages on Transmissions, Motorcycles, and Seal Leaks. If your engine or transmission needs internal cleaning or you need to stop a leak, you have come to the right place.

Do not use Auto-Rx® Plus in any engine where oil and gas are mixed together.

Auto-Rx® Plus also cleans deposits from beneath rotational seals, causing no swelling or degradation to the polymer seal material, and in many cases, it can effectively slow or stop rotational seal leaks . It is designed to safely turn back the clock on lubrication system contamination. Periodic use of Auto-Rx® Plus will reduce wear and maintain peak performance by keeping a clean oiling system.



Yes, a solvent will clean the engine… but at what cost? A solvent flush will clean out deposits left from the use of low-quality oil. If you use a good-quality oil, there is no need to ever use a solvent in your engine. Why? Because the engine has nooks and crannies where oil remains and does not get drained out during an oil change. The residue still has solvent in it that will contaminate your fresh oil. The solvent remaining in the residue would break down the fresh oil and reduce the oil’s capacity to lubricate properly.

Auto-Rx® Plus is “green chemistry” and can do no harm to the engine. A solvent is made to break down oils, and for that reason, we would never recommend using a solvent. The chart below shows how Auto-Rx® Plus stacks up to solvent flushes:



Must be removed after use, usually 5-10 minutes
Remains in the engine; works while you drive
Changes oil viscosity properties
Has no effect on oil chemistry or viscosity
May remove contaminants in chunks that could get caught in the oil pickup screen or a piston port
Liquefies contaminants that are carried to the oil filter and removed with filter replacement
Toxic, hazardous, shock chemistry
Nontoxic, nonhazardous, NO shock chemistry
No oil change removes everything; some of the solvent flush will remain in the pan and continue to circulate in the engine; over time may destroy seals or cause other damage
Some of the Auto-Rx® will remain in the oil pan, continuing to work, keeping the engine clean
