Oil Change – Additives You May Encounter

Motor oil is designed to protect a vehicle's engine by lubricating and cleaning the engine parts. While its chemical properties allow the oil to do this on its own, additives enhance this effect. By simply getting an oil change, significant improvements can be granted to your car's performance.

While at a shop for an oil change,Guest Posting you may have questions regarding their use of additives to enhance an automobile's performance. Additives to motor oil serve a number of purposes and can enhance the oil's lubricating and cleaning effects on the engine. Detergents and dispersants are some of the most common additives. When metal parts such as the pistons, rods, and bearings grind together, small metal particulates break down off of these parts. The detergent and dispersant additives break down these byproducts, and clean them out of the engine before the impurities can cause any major damage. The byproducts of combustion, such as oxidation and silica are also removed with dispersants. There are additional modifiers and additives that are used to protect the engine parts, either from preventing too much friction or prohibiting corrosive build-up. Alkaline additives neutralize acidic oxidation to prevent corrosive build-up, which can also damage the vehicle. Friction modifiers protect the metal parts by adding additional lubricant, which reduces friction as the metal parts grind together; this adds to the fuel economy, meaning that the engine can run more efficiently. Although most of these chemicals are added post-consumer, commercial lubricants have small traces of zinc as an anti-wear additive to protect the contacting metal pieces. An oil filter removes some of the impurities from the oil that are not dissolved by the dispersants. This is an important addition to the oil's effectiveness, because if these impurities become exposed to air and continue to circulate, they will cause sludge build-up that will destroy the engine.

Other modifiers to what's going into your car during an oil change can affect the viscosity, or thickness of the oil in extreme temperatures. Multigrade oils have polymer additives that allow the lubricant to withstand cold or hot extremes. These are useful in high-performing engines in extremely cold environments. If the oil cannot flow easily and lubricate the parts in cold weather, the engine cannot run at maximum performance. High performing engines also get very hot, and some lubricants will vaporize and leave engine deposits if they cannot handle the extreme heat. When getting an oil change, keep in mind that an engine that uses oil that can withstand high temperatures will also retain more oil. Petroleum oils normally cannot withstand extremely cold temperature. Wax impurities in the oil will crystallize and make the oil too thick to properly lubricate the metal parts. Pour point depressants and wax crystal modifiers prevent the petroleum from becoming thick in cold conditions.

Consider oil additives when preparing to deal with extreme conditions through an oil change. Small amounts of zinc are added to commercial motor oils to protect the engine components, however, other additives will prevent rust and corrosion. Choosing the right modifiers for each engine can enhance engine performance and reduce the frequency of oil changes due to sludge or improper lubrication.
