DuraLube and Prolong
Duralube and Prolong contain highly chlorinated paraffins, which can demonstrate some incredible EP (Extreme Pressure) lubricating properties. However, as with any chlorinated parafiin (CP), they will wind up generating acids in your engine that will ultimately attack bearing surfaces (and just about everything else). CP's are used in paints, adhesives, caulks & sealants . Doesn't sound like something we want in our engine.
Bottom Line --- DuraLube Is Snake Oil !!!
I have made many posts here (search under Slick 50, zMax, MMO, Marvel Mystery Oil (MMO), DuraLube) regarding the HAZARDS of using any additives. There are a few good advantages to additives ... but VERY few. It's the fact that oil chemistry is a science and many hours and lots of $$$ goes into blending oil. To think that an additive maker can come out with something that works in improving the quality of an oil without disturbing the existing oil's chemistry is definitely not thinking about the long term consequences. Chemistry clash is a good reson not to mix differant oils and/or additives to achieve your own "homebrew".

Few, ..... very, very, very few ..... additives actually show a difference in performance and those that do are usually associated with an engine that has been somewhat neglected for a while.

Gasoline Additives
Do I recommend gas additives, yes Amsoil Performance Improver Gasoline Additive, which is ideal for both fuel injected and carbureted systems. It dissolves and removes fuel system deposits and other contaminants for improved power and overall performance in gasoline engines and reduces PCV and EGR system deposits. It improves engine idle, response and starting, but only if the injectors were coked up, the intake valves were loaded up, etc. In a well operating engine that is basically clean, I have seen no perceptible difference.

THE ROLE OF MOTOR OIL
Before we can discuss what makes a good motor oil, it helps to understand what role motor oil actually plays in the performance of an engine.
While motor oils serve a variety of functions, they are primarily necessary to lubricate and to cool the engine. When the engine is at rest, the motor oil sits in the bottom of the engine block in what is called the oil pan. Upon start-up, an oil pump feeds oil from the pan to the oil distribution system by means of a network of passages, tubes, grooves and holes leading to the engine bearings and other surfaces needing pressurized oil for lubrication. Other parts, like the overhead valve system, receive a carefully controlled quantity of non-pressurized oil through splashing or spray.
In addition to lubricating and cooling engine parts, motor oil must allow easy starting, protect the engine from corrosion and oxidation, keep the engine clean, form a tight seal between piston rings and cylinder walls and help the engine use fuel efficiently.
In days gone by motor oil was made from the throwaway byproducts of a barrel of crude oil after everything useful was taken from it. In those early days the filter, if you had one at all, was a by-pass type, filtering only a small percentage of the oil. In some instance the filter was little more than a screen and the oil was changed every five hundred or thousand miles. (Some of us recall grandpa's stories of tires needing to be changed on every trip to town, the idea of longevity being somewhat foreign back then.)
As cars and their engines became more sophisticated, so too the requirements of a lubricant became increasingly demanding. In the 1960's jet fighter pilots and their mechanics were becoming aware of the advantages of synthetic oils, and a few of them experimented with the notion of synthetic lubrication for automobiles. One of these pilots, Lt. Colonel Albert J. Amatuzio, went further than the haphazard experiments of his peers. His ten year quest resulted in the development of AMSOIL, the first automotive synthetic motor oil to exceed the certification requirements of the American Petroleum Institute (API).
SYNTHETIC VS. CONVENTIONAL PETROLEUM (Crude or Dino) MOTOR OIL
Conventional lubricants are refined from crude oil which has thousands of types of molecules. Refining is a process of physically separating the impurities from the oil and further separating the light and heavy components. Because refining separates products by weight, it groups molecules of similar weight and dissimilar structure. The result is a lubricant with a wide assortment of molecules. Some of the substances in crude oil are detrimental to lubrication. Paraffins, for example, are a common conventional oil contaminant that causes motor oil to thicken in cold temperatures.
Synthetic motor oils are made from pure chemicals, not refined crude. Their components are chemically reacted to produce finished products with pre-designed performance characteristics. Because of their molecular uniformity, they excel in reducing friction, which improves fuel efficiency, controls heat and reduces wear. This molecular uniformity also helps synthetics resist thinning in hot temperatures and thickening in cold.
