Oil Change - Get The Right Lubricant

While newer vehicles can go up to 10,00 miles without an oil change, certain circumstances can affect this frequency. Likewise, older vehicles with a lot of engine miles will also need more frequent maintenance. However, knowing the right kind of motor oil to use in the engine can also have an affect on the frequency of an oil change. 

Viscosity is the measurement of a motor oil's thickness, and it is one of the most important factors in its effectiveness. Keeping the engine parts lubricated is the oil's most important job because engine parts that are not properly lubricated become vulnerable to excessive heat, as well as wear and tear. While the oil will remain thick enough to properly lubricate the engine parts at certain temperatures, the lubricant will become more thin as the engine gets hotter. Therefore, cars that must operate in extremely hot environments will become more vulnerable to wear and tear because the oil may not be able to keep the parts lubricated at these high temperatures. Extremely cold temperatures can also be a problem if the lubricant freezes, and simply cannot flow to keep the parts properly coated. Luckily, there are motor oils that are specially made to withstand extremely hot or cold temperatures. Viscosity index is used to measure the oil's ability to remain thick in these extreme environments, and it is represented by the set of numbers written on a bottle of motor oil. A viscosity index between 0 and 25 indicates an engine oil that is best suited for winter or lower temperatures. Likewise, a viscosity index of around 60 indicates a lubricant that is better suited for extremely hot temperatures temperatures. 

Many engine lubricants come with additives to help enhance the performance and longevity of certain vehicles. For instance, high mileage motor oil includes a number of additives to help clean the engine, and prevent leakages. Older engines tend to be less efficient because of built up engine sludge and small leaks. Although these additives can be used in newer engines, they are most effective in engines with over 75,000 miles. Rust and corrosion additives help to prevent oxidation of the metal parts inside the engine. This is especially helpful in wet environments, where the moisture reacts with these parts, causing harmful corrosion and rust. 

Knowing how to choose the right lubricant is just as important as being diligent about getting an oil change. Although the engine is designed to last, there are certain conditions that can severely cut the life of the engine short.
