Why does oxidized lubricating oil cause corrosion?

In addition to oxidation, nitration, temperature, contamination, high shear rates, corrosive environments or depletion of additive packages are the main factors that shorten engine oil life.

Engine oil performs a very important function, and for this reason it is vital to change the oil at the time recommended by the vehicle manufacturer.

The time and use we give the engines does it. This normal process is known as deterioration or degradation of lubricating oil, which reduces the oil's ability to perform its essential functions. But also to the loss of other important functions, such as cooling, cleaning, protection and sealing, which are gradually lost.

However, there are other factors that cause engine oil to deteriorate faster. 

oxidation This is one of the main causes of lubricant wear. This leads to a change in the molecular structure of the oil. When lubricating oil comes into contact with an oxidizing element, such as oxygen, and a chemical reaction occurs, the viscosity increases and acidic products are formed that can damage metal components, such as car parts, that the lubricant bathes.

Other consequences of oxidation can be the formation of sludge, varnishes and varnishes.

Oxidizing compounds cause corrosion and contribute to the formation of deposits, causing clogging of valves and circuits and, as a result, equipment failure. This reaction accelerates as the oil temperature rises.

The time and use we put into engines means that engine lubricating oils can lose their properties. This normal process is known as deterioration or degradation of lubricating oil, which reduces the oil's ability to perform its essential functions. But also to the loss of other important functions, such as cooling, cleaning, protection and sealing, which are gradually lost.

Other important factors that shorten engine oil life are: nitration, temperature, fouling, high shear rates, corrosive environments or depletion of additive packages.

That is why it is so important to change the oil so that it does not quickly lose its properties.
