Lets start with the fact many posts show that knowledge of what can cause sludge is in the eyes of the beholder. Below is fact
Soot - This is fine powder that is a product of incomplete combustion. This carbon substance enters the crankcase with exhaust blow-by gases that escape past the piston rings. Since soot is a very fine powder, it thickens oil by a process called "soot loading." It gels the oil like a cake mix thickens milk.
Engine heat - A natural result of internal combustion, takes its toll on your motor oil. In the presence of air, oil undergoes a process called oxidation, which becomes more severe as the temperature increases. Oxidation thickens the oil and produces corrosive acids. Left unchecked, your oil would degrade into a tar-like mess.
Fuel - Enters your crankcase with exhaust blow-by gases in unburned and partially burned forms. It is chemically unstable; therefore, it reacts with itself and the oil to form gums and varnishes that create even more oil thickening.
Water - Gets into your crankcase typically through condensation or in exhaust gases that escape past the piston rings. It is your engines job to get rid of this moisture by operating at sufficiently high temperatures. However, all engines operate periodically at low temperatures and experience some water contamination. When this occurs, water becomes emulsified. That is, it is absorbed by the oil, which thickens the lubricant. As a result, the oil does not flow or cool well. The increased viscosity can cause the oil to burn, creating engine deposits.
Acids - When fuel burns, some products of combustion react with moisture in the system to form acids. These include sulfuric, hydrochloric and organic acids. Sulfur-based acids are undesirable because they attack the oil, reducing its detergency. Organic acids react with unburned fuel to promote sludge and varnish. In addition, acids can cause additive settling, or dropout.
Dirt - Most people associate dirt with engine wear. It can also play a role in sludge formation. Wear of piston rings and cylinder walls causes an increase in piston blow-by. Since the exhaust gases contain many harmful by-products, their presence in the crankcase should be minimized. Nonetheless, some of these compounds will escape past the rings. Auto-Rx® will fight the harmful effects of dirt. The dispersants suspend and isolate the dirt, soot and other solid particles that work their way into the oil. That is why an oil change is necessary to flush the unwanted components.
Heat, when combined with engine oil, also creates harmful byproducts such as sludge, varnish and sulfur. When these byproducts combine with condensation and airborne pollutants (dirt, soot, industrial ash, etc.), contamination build-up is created. Contamination build-up enters your engines oil passages, limiting the amount of oil that can get to your engines most vital parts. This build-up prevents engine oil from properly lubricating your engine. When proper lubrication fails to occur, uneven hot spots are created underneath contamination deposits. Resulting in a dramatic decrease in your engines performance and will shorten the life of your engine.
Unfortunately, there is not much that engine oil can do to reduce the harmful effects of all these contaminants. Oil changes every 3000 miles and a maintenance program of Auto-Rx® are the best way to take care of this problem.
It is said that there are no oil additives available that will help solve the sludge problem. We know of many vehicles that have had sludge problems and Auto-Rx® has restored not only the life to the engine but also has the ability to clean the ring packs, restore compression and improve combustion. This helps keep your car out of the shop. Auto-Rx® does not profess to do everything (it cant fix broken parts); however we know it does the above - its guaranteed.
As a maintenance program, use 3 oz of Auto-Rx at every oil change. This will keep the sludge and contaminates out of your engine. Our Auto-Rx® blog was set up for the many thousand of people that may need their car engine cleaned. Whether your engine is just a little dirty or all sludged-up, this is the only chemistry that cleans Ring Packs while you are driving. Most people dont realize that 95% of engine problems are caused by contaminants such as carbon, sludge, dirt and other abrasives. All these things combined with engine oil and extreme heat create uneven hot spots and extremely harmful byproducts, the result? A dramatic decrease in your engines performance.
Auto-Rx® (U.S. Patent #6,544,349), is a specially formulated, all-natural metal cleaner designed to thoroughly clean the internals of your engine. Many years of real-world testing have gone into this formulation.
Auto-Rx® extends the life of your engine - Heres how: for automotive applications, Auto-Rx® uses your engines oil as a carrier, Why? Because Auto-Rx® is thicker, it requires another liquid for effective dispersal to your engines lubricated parts. Simply add Auto-Rx® to your oil and drive your vehicle normally! Auto-Rx® will work as you drive, liquefying the dirty deposits of sludge, carbon and other debris in your engine, and preventing clogs in the flow of your engines oil.
