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 engine permanently. You need Auto-RX® Plus temporarily, but also keeping a small amount (maintenance dose) in the engine at all times is not a bad idea. When you pour Auto-RX® Plus into your engine, 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. 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® Plus is not a solvent, a friction reducer, an oil enhancer, or another magic potion. Adding Auto-RX® Plus does not change the properties of your host oil. It is safe chemistry with proven results.
Auto-Rx® Plus is your best choice for Engine Sludge Removal.
