Got a problem with an engine, transmission, power steering, or rear main seal leak?

Then, use Auto-Rx® Plus and get proven results! It has been sold on the Internet for over 12 years.

Remove Engine Sludge and Clean Transmissions and Power Steering Units!

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, the use of Auto-Rx® Plus for preventative maintenance will ensure your engine remains free of contaminant build-up.

You might wonder, “If this stuff is so great, why don’t the oil companies use it as an additive?”

First, Auto-Rx® Plus is not an additive. In your mind, think of Auto-Rx® Plus as one thing and your oil as another. Your oil lubricates. Auto-Rx® Plus cleans. The primary purpose of oil is to lubricate. Auto-Rx® Plus has only one job — that is to clean.

There is only so much “room” in oil. Oil companies have experimented with various detergent/cleaner combinations in oil and have been able to take the cleaning only so far. For long-term equipment operation, they cannot take it far enough. That is where Auto-Rx® Plus has its important role.

Auto-Rx® Plus is not applied to “cure” some deficiency in the oil. Oil is not deficient. However, because we have to stay within the laws of physics and chemistry, oil cannot do much more than marginal cleaning if it is to do its primary duty, which is to lubricate.

You need oil in your equipment permanently. You need Auto-Rx® Plus temporarily (though some people leave it in their oil all the time with no problem).

When you pour Auto-Rx® Plus into your oil reservoir, it mixes with the host oil. The oil carries Auto-Rx® Plus through the lubrication system. As Auto-Rx® Plus encounters abrasives, dirt, and grime, it dissolves that harmful stuff into clumps that are too small to clog any passageways, but large enough to catch in the filter.

That is how it works. Auto-Rx® Plus is not a solvent, a friction reducer, an oil enhancer, or another magic potion — although these may be side benefits. Auto-Rx® Plus is added separately. It does not change the properties of your host oil. It is safe chemistry applied on a periodic basis as part of a common-sense preventive maintenance program.

If you have ever taken apart an engine or other industrial 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 safely removes sludge, dirt, carbon build-up, and other contaminants from engines, turbochargers, piston rings, transmissions, power steering, differentials, and motorcycles.  Auto-Rx® Plus safely rejuvenates seals, reducing or eliminating oil leaks. (US Patent #6,544,349)

Great Compression Stats

compressionstats Just completed my 2nd Auto-Rx application. I don’t know that there are enough superlatives to express how pleased I am with Auto-Rx in a 1997 Taurus 3.0 Vulcan, heavily coked piston rings, very poor compression. There were two applications of Auto-Rx. First was an experiment with Frank and Gary; second was a traditional treatment. The initial test was 2x the dose for 1K miles, followed by a 2K-mile rinse. The second application was at 90k miles with 2.5K-mile application and 2.5K-mile rinse. The final result? All cylinders are now at full compression! The last lagging cylinder (#5) is now up over 180psi in yesterday’s compression test, along with all the rest. The chart shown is a recap of the compression in psi, with each reading taken at the beginning of the event. Auto-Rx flat works. Period. While it cannot reconstruct worn metal, it sure can do nearly anything related to byproduct contamination. The only thing I regret is that I didn’t take the pistons out for pictures of the coking and then reinstall them and run the Auto-Rx. On the bright side, I didn’t have to, because the Auto-Rx did all the work for me! And that’s the whole point, isn’t it? Why tear down an engine to repair the cumulative effects of combustion byproducts when Auto-Rx can do it for you! It’s beyond any competition in the market, and it deserves all the praise it garners.
