What causes engine oil to become sludge or commonly referred
to as oil sludge?
Sludge inside the engine is typically in the form of a gel
due to oxidation resulting from deposits, combustion residues, or old oil crust
mixing with fresh oil.
These combustion residues will clump and adhere to the
surface of the car engine components.
Usually, if left unattended, it will have an impact on
damaging the car engine.
Vehicles that have started to develop sludge should not be
left unattended.
If left unattended, this sludge or oil mud will clog the
engine oil channels, causing the engine to work inefficiently.
Consequently, the engine will perform poorly, leading to
higher fuel consumption.
4 Causes of Engine Oil Sludge
So, what causes the engine in these vehicles to become
sludgy?
Well, below, we summarize the 4 causes of engine oil sludge:
1. Inconsistent Oil Brand Change
Each lubricant is made with a formula that suits the
materials and characteristics of the engine, including the use of additives.
As a result, each oil brand will have different additive
contents from one another.
Sludge appears when two different oil brands cannot mix well
and leave sediment.
It is advisable to avoid frequently changing oil brands when
replacing engine oil.
2. Using Different Types and Grades of Oil
Even if they are from the same brand, engine oil can have
different qualities, ranging from mineral oil, semi-synthetic, to full
synthetic oil.
Frequently changing the type and grade of oil can affect the
performance of the car engine.
The engine's performance and protection may decrease,
leading to seal damage, a shorter engine lifespan, and the formation of oil
sludge as engine dirt increases.
3. Using Counterfeit Oil
Counterfeit engine oil does not have the same quality as
genuine engine oil.
Using counterfeit oil continuously will damage the engine
because it cannot provide the necessary protection and lubrication the engine
needs.
Counterfeit oil can produce sludge due to its damaged
chemical compounds that precipitate together with engine dirt.
4. Neglecting to Change the Engine Oil Filter
The oil filter serves to filter impurities in the engine oil
that come from the engine compartment.
When the oil filter is not replaced regularly, impurities
will accumulate in the oil filter and form oil clots.
If neglected, these clots will block the oil filter and
impede the circulation of engine oil. Therefore, it is essential to regularly
change the oil filter according to the manufacturer's recommendations.
