Miscellaneous Oil Lubricant Additives

Oil that works for a motor engine fuel will be easily contaminated by strong acids such as sulfur and nitric as a by-product of the combustion process. These strong acids are certainly harmful to engine life if not addressed properly. The detergent additive is added to the oil as a neutralizer of the strong acid and removes the neutralization results from the surface of the machine components. The detergent also forms a film coating on the surface of the component to prevent sticking of the crust on the surface of the component. Detergent additive agents include phenolates, sulphonates, and phosphonates of alkaline and alkaline-earth elements, such as calcium (Ca), magnesium (Mg), sodium (Na) or barium (Ba). When you choose the best oil for your vehicle, then choose the oil that actually contains the materials that are needed for your vehicle. With us, Sears Oil Change provides the best oil for you.

The dispersant additive added to the oil lubricant serves to keep the incoming foreign particles mixed with oil to keep it separated from each other so that no impurities precipitate are formed. These foreign particles can be mud, lacquer, dust, oxidation, water, and so on. A long chain succinimide hydrocarbon such as polyisobutylene succinimide is used as an oil lubricant dispersant. Pour-Point is the lowest temperature point where the oil can still flow. Wax crystals are formed from mineral oil at low temperatures and decrease oil fluidity. Pour-point depressants block the formation and collecting of wax particles so as to keep the oil “water” at low temperatures. These additives are obtained from Polyalkyl methacrylate copolymers.

Oil viscosity will drastically decrease at high temperatures. Low viscosity will decrease the ability of the oil to lubrication existing system. Special additives are added to keep the oil viscosity at the level permitted by the engine so that the oil film layer is maintained even at extreme temperatures. These special additives are able to maintain oil viscosity, especially multigrade oil, to deal with low or high temperatures. The acrylate polymer is the most commonly used material as this particular additive. The oil lubricants that work on machines such as combustion engines, compressors, gearboxes, will not escape the motion of stirring. Naturally, this stirring motion will aerate lubricating oil, so it can cause air bubbles and even foam. The foam will not only trigger the oxidation of the oil, but it will also decrease the oil lubrication effect. Dimethyl silicone is the most commonly used agent as an anti-foaming agent additive.
