What is the origin of the 3-month synthetic oil change myth?
The origin of the 3-month synthetic oil change myth is not well-documented, but it is believed to have started in the early days of synthetic oil development. At that time, synthetic oil was a relatively new technology, and there was limited data available on its performance and longevity. As a result, manufacturers and mechanics may have erred on the side of caution and recommended more frequent oil changes to ensure the longevity of the engine. This approach was likely influenced by the traditional oil change intervals for conventional oil, which were typically every 3,000 to 5,000 miles.
Over time, the 3-month synthetic oil change myth has been perpetuated by various factors, including misinformation, marketing strategies, and a lack of understanding about the properties of synthetic oil. Many people assume that synthetic oil is no different from conventional oil and that it needs to be changed just as frequently. However, this is not the case. Synthetic oil is designed to last longer and perform better in extreme temperatures and driving conditions, making it possible to go longer between oil changes. In fact, many modern vehicles equipped with synthetic oil can go up to 10,000 miles or more between oil changes, depending on the manufacturer’s recommendations and driving conditions.
How does synthetic oil differ from conventional oil?
Synthetic oil and conventional oil differ significantly in terms of their composition, properties, and performance. Synthetic oil is made from chemical compounds that are designed to provide superior lubrication, wear protection, and thermal stability. It is typically made from a combination of polyalphaolefins (PAO) and polyalkylene glycols (PAG), which are synthesized from chemical reactions. This process allows for the creation of a lubricant that is more consistent in its molecular structure and properties, resulting in better performance and longer life.
In contrast, conventional oil is refined from crude oil and may contain a variety of impurities and contaminants. While conventional oil can provide adequate lubrication and protection for many engines, it may not perform as well as synthetic oil in extreme temperatures, high-performance driving, or under heavy loads. Synthetic oil, on the other hand, is designed to maintain its viscosity and lubricating properties even in the most demanding conditions, making it a popular choice for high-performance vehicles, turbocharged engines, and driving in extreme climates.
What are the benefits of using synthetic oil in my vehicle?
