Naphthennic Oils And Parafinic Oils

It is not common knowledge, even among mechanics, that there are two types of mineral oils - Naphthennic Oils and Parafinic Oils.

Naphthennic Oil – Burns easily, having a flash point of around 160 deg. C. and emulsifies in water or steam. This type of oil evaporates and will retreat from metal bearing surface areas when subjected to heat. This can lead to equipment break down. Most equipment breakdowns are caused, because Naphthennic Oil will "shear" easily, allowing metal surfaces to come into direct contact with each other and bind together. Oil will shear when the oil molecules break down under stresses such as excessive heat. Naphthennic Oil contributes to creating excessive heat and hastens engine wear. Parafinic Oils on the other hand, have a long chain molecular structure. Unlike Naphthennic Oils, when the molecular "chain" in Parafinic Oil breaks, it simply forms into smaller chains and so tends to maintain it’s lubrication.

Naphthennic Oil is relatively cheap to produce, and is in very plentiful supply World Wide, so this type of oil accounts for around 98% of the oils on the market. By-products of Naphthennic Oils include tar, CFC’s, bitumen, acetone, carborundum, butane, hydrocarbons and plastics.

Imagine what is happening inside your motor with "nasties" like those just described in your common oils. Carborundum is what is placed on emery paper as the rough base for the cutting compound. Over time, tar residues from the combustion process gums up the piston rings, which prevent the rings from expanding to follow the taper of worn cylinder barrels. It is little wonder then, that engines wear out ahead of time, with the carborundum contributing to "Cylinder Taper", and tar, bitumen, and plastics binding the piston rings into the piston grooves preventing the piston rings from working efficiently.

Parafinic Oil - Is mainly used in Cosmetics, the manufacture of high grade plastics, and it is also used as a major source of Additives to fortify ordinary Naphthennic engine oils. Parafinic Oils are hard to burn, having a flash point of around 360 deg. C. As has been explained already, Parafinic Oils greatly resist shearing, and they will not mix with water. Neither will Parafinic Oils emulsify or break down with either extreme heat or extreme cold. Parafinic Oils will not carbonise and they do not contain any waxy solids.

Additives -- The modern vehicle engine is often a highly sophisticated piece of machinery. The lubrication in these motors is all too often stretched to the limit, placing enormous stresses on the engine’s oils. Only high quality oils with sufficient additives can withstand these stresses for any length of time. Many oils on the market today only have a lifespan of about 2000 to 3000 klms. A cheap base stock of Naphthennic oil with a minimum quantity of cheap additives simply cannot last. The additives that have been put into the oil are either depleted or they get used up, and the oil breaks down with heat and condensation. Carbon and sludge start forming, and it is only a matter of time before you have a noisy, worn out, smoky engine.

Bi-tron -- is not an additive -- it is a superior metal treatment. Bi-tron does not contain any plastics, PTFE’s, resins, Teflon’s or heavy metals. It is simply a 30W oil that has been changed at the Molecular Level so that it is attracted to heat and to metals, unlike ordinary oils which are repelled by heat from heated metal. Bi-tron has an extremely strong resistance to oil shear – stronger even than Parafinic Oils.
