You might wonder, "If this stuff is so great, why don't the oil companies use it as an additive?"
First,Auto-Rx is not an additive. In your mind, think of Auto-Rx as one thing and your oil as another. Your oil lubricates. Auto-Rx cleans. The primary purpose of oil is to lubricate. Auto-Rx has only one job -- that is to clean.
There is only so much "room" in oil. Oil companies have experimented with various detergent/cleaner combination's 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 has its important role.
Auto-Rx 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 temporarily (though some people leave it in their oil all the time with no problem). When you pour Auto-Rx into your oil reservoir, it mixes with the host oil. The oil carries Auto-Rx through the lubrication system. As Auto-Rx encounters abrasives, dirt, and grime, it dissolves that harmful stuff. And it causes that junk to coagulate into clumps too small to clog any passageways, but large enough to filter out.
That is how it works. Auto-Rx is not a solvent, a friction reducer, an oil enhancer, or another magic potion -- although these may be side benefits from Auto-Rx. You add Auto-Rx 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 a transmission, you know what dirty oil can do to bearings and other surfaces. Those who have used Auto-Rx no longer see the results of that dirty oil. Why should you?
