Viscosity Comparison:

Engine oils come in different grades or viscosities which help in determining if the oil is suitable for lower temperatures or normal temperatures.

Liqui Moly Special Tec is a multi grade motor oil which comes in 5 different grades which are 0W-16, 0W-20, 5W-20, 5W-30, 5W-40 and 10W-30.

Liqui Moly Special Tec SAE grades

According to the SAE standard, this motor oil is more suitable for lower temperatures. However, the 10W-30 grade or viscosity is more suitable for normal temperatures.

Here for example, in the 5W- 20 and 5W-30 viscosities, the digit 5 stands for the grade at low temperature with W indicating winters and the 20 and 30 digits indicating the grade at normal temperature. The engine oil is normally thin during start up as the engine is cold and thus it helps spread around all engine parts quickly.

The consistency of the oil thickens once the engine heats up so that too much oil is not used up.

Moreover, the viscosity index improvers further facilitate in maintain and boosting performance even under extreme temperatures. Liqui Moly Special Tec meets and exceeds the API standard and the ILSAC GF-5 standard.

On the other hand, Molygen motor oil is available in 5 different viscosities which are 5W-20, 5W-30, 5W-40, 5W-50, 10W-30 and 10W-40. According to the SAE standard, this motor oil is suitable for both lower and normal or higher temperatures.

Molygen SAE Grades

To be more specific, the 5W-20, 5W-30 and 5W-40 viscosities are more suitable for lower temperatures and the 10W-30 and 10W-40 viscosities are more suitable for higher temperatures.

Moreover, the digits 5 and 10 indicate the grade at low temperature with W indicating winters and the 20 and 30 digits show the grade at normal temperature.

Furthermore, the viscosity index improvers provide outsanding stability and maintain performance under extreme driving temperatures.

Molygen meets and exceeds the API standard and the ILSAC GF-5 standard.

When it comes to the reduction and prevention of any harmful deposits and sludge built up, Liqui Moly Special Tec and Molygen perform equally great and are both efficient.

Oil burn-off protection

It is important to have oil burn off protection since the more the oil burns off the more the fuel is consumed. This process normally happens when the engine stays heated up and the oil molecules begin to evaporate, and thus less oil is left in the engine.

This issue would mean you shall have to replace your engine oil more frequently than normal.

Moreover, this issue leaves the engine unprotected and can produce harmful emissions which can increase harmful deposits on engine, decrease performance and have poor low temperature start.

Liqui Moly Special Tec uses antioxidants to stop any oil molecules from evaporating when the engine is heated up along with reducing any harmful emissions.
