Synthetic Lubricants – Semi vs. Fully-Synthetic

Share this page on...

Synthetic Lubricants

Synthetic lubricants are available to all motor users in the form of fully-synthetic and semi-synthetic when they have been mixed with natural lubricants.

Why Artificial Is Better Than ‘Natural’

Scientists have spent time developing artificial lubricants that will perform better than natural ones. These artificial lubricants are better because they carry less of the inadequacies and have improved properties over the natural ones.

Organic oils are thought to be unstable. Synthetic oils have antioxidant additives so they are less affected by high temperatures. For example, when an engine starts up, artificial oil will flow more easily. This is because the chemical composition and properties of synthetic oils is controlled to give a better performance.

When compared to organic oil, artificial oil provides:

  • 5 times better engine cleaning
  • Protects engine parts up to 3 times more
  • Less than 50% the amount of engine damage

Advantages

Artificial engine lubricants provide the following advantages:

  • Natural lubricants contain unbalanced hydrocarbons and sulphur, which isn’t good for the engine. Whereas, the artificial oils don’t contain any of these.
  • Additional uniform and reliable molecular structure – which decreases the liquid friction stages
  • If an engine needs a particular lubricant, it can be created especially for that engine
  • Synthetic lubricants are intended to perform in the extreme circumstances encountered in contemporary engines

Why do synthetic oils perform so well?

Properties Of Artificial Oils

Subsequent Benefits

As overall viscosity is low, friction is reduced which means flow properties are improved Engine performance and fuel economy are improved, while the temperature of the lubricant remains low
Organic oils are affected by changes in temperatures, whereas artificial lubricants aren’t Fewer deposits are in the oil as there is no need for viscosity modifier. Also, engine wear is decreased as the oil doesn’t become thin when hot or dense when cold
Even in the highest temperature, the oil will retain its viscosity and its shear resistance If a vehicle is carrying a heavy load or travelling at high speed, the oil will protect the engine

    I have a speed triple bike should i use sinthect or semisinthec oil & why thanks ?

      Hi Richard, it’s always best to check with your bike manufacturer however, my guess would be to use fully synthetic.

      The additives used in the fully synthetic oil blend will be much better than the semi-synthetic but, as with anything that is better, expect to pay more!

      Thanks for your question!
