Useful Info About Synthetic Lubricants for Motors

In short terms, synthetic oil is a lubricant that uses artificially made chemicals compounds. It can be made from chemically modified ingredients or can be synthesized from other materials. Moreover, it’s quite important to know that it is not manufactured using crude oil and it is relatively pure compared to conventional oils. In fact, this type of lubricant is used to substitute refined petroleum oil when the motor is operating in extreme weather conditions. However, this doesn’t mean that a synthetic oil cannot be used when the engine is operating at normal temperatures. More than that, when purchasing a lubricant for your car motor, you should take into account the fact that a regular oil will provide you with 3.000 miles of drive time before you change it. On the other hand, with this type of oil, you are looking to bump up that 7.000-10.000 miles before replacing it with a new one. These types of lubricants will provide a lot of benefits that will keep your motor running at peak performance. However, to better understand their benefits, you must know that there are three types of lubricants available in the current market, such as:

  • conventional minerals oils which are the traditional ones
  • semi-synthetic which is formed from a blend of conventional and synthetic types
  • full synthetic oils which are the latest and the most popular lubricants nowadays

Generally speaking, synthetic lubricants are made from advanced refining process and they are more quality and purer than conventional oils. The refining process removes impurities from crude oil and enables molecules in the oil in order to be customized to the demands of modern car engines.

Choosing Between Synthetic and Conventional Motor Oils


When it comes to picking the right type of oil for your car, there are some aspects you must pay attention to. You can choose either a conventional type that is the most common one, or an innovative synthetic oil that is becoming more and more popular. It’s important to follow the owner’s instructions and read the label very well, but knowing a thing or two about every type will also help you decide.

  • Conventional lubricant

  • This is the traditional oil available in several viscosity levels, usually a 5W-20 or 5W-30 for lower ambient temperatures, and 10W-30 for higher temperatures. If you pick this one, keep in mind that you need to change it regularly, as well as the filter, to ensure the maximum performance of your car. The proper changing interval is 4 months or 4000 miles but you could go for 6 months with the same oil without causing any damage to the engine.

  • Semi-synthetic lubricant

  • For higher temperatures and heavier loads, the blend of synthetic and organic oil is the most appropriate. The fact this oil lasts to higher temperatures means it evaporates harder so the fuel economy will be increased. Generally, this type is chosen for large vehicles like pickup trucks or SUVs that require more engine protection. The price is a little higher than conventional oils but it’s still an affordable choice.

  • Full synthetic lubricant

  • The last type is the most high-end, designed for the latest engines designed by top brands like Mercedes. It’s of a superior quality, with a long-lasting performance and an increased engine protection. Choose this oil for low and high temperatures as well because it manages to remain at the proper viscosity regardless of the degrees. Although this type is the highest quality, it’s not designed for any type of engine and it’s also very expensive, sometimes being a useless investment.
