Auto-Rx® Plus Read Extended Benefits for Engine Sludge

For vehicles with traditional engine sludge, we recommend using a maintenance dose to keep sludge under control.


Add 3 ounces of Auto-Rx® Plus, as part of a fresh oil change.


Repeat this dose with each fresh oil change.

Auto-Rx® Plus in closed automotive lubrication systems

Closed systems include transmissions, power steering and differentials. These lubricants are recommended for 30,000 to 60,000 miles. However, once they are used past the recommended service interval or beyond, contaminants from heat and metallurgy stick to the working internal parts of each component. The greatest thing you can do to protect these expensive systems is to add a small dose ofAuto-Rx® Plus and then run 1,000 miles before having these vital fluids replaced.

* For an automatic transmission, add 6 fluid ounces or the equivalent of ½ bottle of Auto-Rx® Plus.

* For a power steering pump, add 3 fluid ounces of Auto-Rx® Plus for this system. ​

After driving the vehicle for 1,000 miles, the results are all the contamination drains with the old fluid. Now you are putting fresh fluids into a clean system. After all, why put fresh lubricants into a dirty system? The new fluid will perform much longer with a clean system!

Rationale for Auto-Rx® Plus Maintenance Dose for Motors

A good majority of Auto-Rx® Plus customers come to our website with serious troubles in their motors. Usually it is due to running extended drains. We all like to hear that an oil is good for X,XXX number of miles. What most people don’t realize, however, is that those X,XXX miles are based on ideal driving conditions. There is a big difference between highway miles and short trip local miles. We all like to hear about the highway mileage rating. Your motor is really a living/breathing machine. Just think about the volumetric amount of air that passes through the combustion chamber just to drive 5,000 miles. Whether it is riding downtown or all on the highway, that volume is huge. Now think about the gallons of gasoline or diesel that you paid for that made those driving miles possible. Well, I have to tell you that is a very sizable amount of air, contaminants, and incomplete combustion gases that pass by the piston rings every mile. These are the two predominant components that promote engine sludge.

Be proactive and avoid major internal engine repairs

Once you have your motor clean following the cleaning instruction, use the Auto-Rx maintenance dose – run 3 fluid ounces of Auto-Rx with each oil change to greatly expand the detergent/dispersant package of your host oil. Or run a full 12 fluid ounce bottle every 4th oil change. Motors are becoming ever more sophisticated and expensive. Keeping the motors internal sensors and working components clean will keep you out of trouble. Auto-Rx is designed to clean while you drive. Most major repairs are a result of dirty parts. Poor compression can be a result of sticky ring packs. With a small investment in Auto-Rx® Plus our product can greatly improve piston ring and cylinder bore sealing. $25 is a lot better than a $2,500 mechanic’s bill. A poor shifting automatic transmission can be caused by sticky shifting modules or a gummed up torque convertor. Auto-Rx® Plus can get in there and free up those shifting modules and your torque converter. Again, $25 is way better than being stuck with a $2,500 service bill. No synthetic or mineral oil cleans contaminants from lubricated engine parts. Oil can’t lubricate and clean at the same time. If there was such an oil, we would have been out of business years ago. We frequently get inquiries from oil companies wanting to add a small amount of Auto-Rx to their brand, but those low dosages will simply not work. Our instructions found on AUTO-RX.COM are clear on the dosages needed to fix your particular problem.

What is Auto-Rx® Plus and why should I use it in my vehicle?

Auto-Rx® was developed as a environmentally safe alternative to the strong solvents often used in the cleaning of industrial equipment. It was discovered that Auto-Rx® worked in a wide variety of applications, including cars, trucks, and motorcycles. The latest blend of this unique product is called Auto-Rx®Plus. Auto-Rx® Plus works faster and outperforms earlier Auto-Rx® formulations. In an engine Auto-Rx®Plus slowly dissolves oxidized contaminant that has build up over time. Tests have shown Auto-Rx®Plus can restore lost compression if the loss is due to stuck or sticking piston rings. Auto-Rx®Plus also has the ability to rejuvenate some rotating seals, often eliminating leaks entirely. In transmissions Auto-Rx®Plus will remove contaminants that prevent the transmission from operating as intended.
