Not All Synthetic Oils Are Created Equal

High-end cars perform better on synthetic oils. However, that does not mean just any old synthetic oil type will do—the different attributes of synthetic oil products must be considered whenever an oil change is part of your German car maintenance in Albuquerque, NM. Here is what you need to know about synthetic oils and choosing the right one for your vehicle.

Categories

Synthetic oils are categorized in a five-group system. Group I oils are the least refined and normally not used for automobiles at all. The lowest grade of synthetic oil for cars is Group II, which is reserved for only the most basic vehicles. Its performance capabilities are only fair to good in the areas of wear prevention, volatility, oxidation and flash/fire point. This is likely adequate for low-performing vehicles, but you do not want to use Group II oils for the higher performing engines in Porsche and Mercedes vehicles.

Higher end oils are in Groups III to V. The highest performance cars require a product from Group V. If you invested in a luxury vehicle with a less demanding engine, you can likely do fine using a Group III oil. It offers better performance than Group II and will help preserve your car engine longer.

The one temptation to avoid when considering oils is choosing a semi-synthetic option. This often seems like a cost-effective solution, since the presence of synthetic oil is assumed to give it the same performance features. However, most semi-synthetic products only contain 30 percent synthetic oil. In many ways, you are merely paying more for a conventional oil that will in no way offer the same advantages as a higher performing Group IV or V oil.

Elements

Synthetic oils offer different elements that support performance. The product that works best for you depends on your engine capabilities and desired performance. Additives, viscosity and lubricants determine the quality and performance of your synthetic oil.

Additives keep oil functional under high temperatures. If you have a hot-burning performance engine with turbo-chargers, you likely desire more additives. The additives help oil last longer under demanding conditions and protect your engine, especially during the rough startup process.

Viscosity measures oil thickness. Thicker oil coats engine components better and flows slowly. Since oil thins as it heats up, you want a higher viscosity oil for use in higher-performance engines. This allows the oil to lubricate better and maintain performance.

Lubricants are either an additive or a base stock for the oil. They often accompany viscosity in coating engine components and ensuring smooth functioning. Usually these are esters, and they are only available in synthetic oils. They improve engine performance and reduce corrosion.
