Facts and Myths about Engine Oil

Many myths about the wrong engine oil that has been trusted by many people as a fact, this is caused by a wrong understanding of product information about engine oil.

The development of machine technology has been very rapidly developing, which used to be suitable for the machines of antiquity. It is not necessarily applicable to modern machines.

Here are some facts and myths about engine oil


Myth 1
Not allowed to use mineral oil that has Paraffin content. Paraffin is the same as wax.

Many people consider paraffin or wax contained in the oil will form a layer on the engine components and create mud.

Fact
Paraffin is one of the ingredients in crude oil that is used as an ingredient in making engine oil.

Many high quality engine oils use this material as a base material.

Paraffin or wax in crude oil is separated during the crude oil refining process and is one of the premium products sold by oil companies.

Engine oil that thickens like mud in the engine is not caused by the wax content in the engine oil.

The main factor causing oil thickening is because engine oil is contaminated by carbon due to the combustion process inside the engine.

The basic properties of oil contain detergent which will absorb dirt from the engine room and if the engine oil is used for too long the engine oil becomes saturated and thickens like mud.

Myth No. 2
Inserting ATF oil into the engine a few moments before changing the engine oil will clean the engine, the reason is that the detergent content in ATF will clean the sludge in the engine.

Fact
ATF oil does not contain detergent chemicals as it is found in engine oil which is designed to withstand the conditions of a dirty combustion chamber.

ATF oil will not be able to eradicate the sludge that is attached to the engine, instead it is feared that if the sludge is released it can clog the oil channels in the oil filter and oil pump which will cause severe damage to the engine.

Myth No. 3
The use of synthetic oil causes oil to easily thicken and become sludge.

Fact
Mud sediment is not caused by the use of synthetic oil, but more on oil that is too saturated due to too long use.

The occurrence of sludge can be prevented by using engine oil in accordance with the recommendations of the manufacturer and oil change at a predetermined time and ensure the crankcase ventilation duct (PCV) is functioning properly.

Myth No. 4
The car lubrication system must be drained if replacing mineral oil to synthetic oil or vice versa.

Fact
Synthetic mineral and oil oils can be exchanged.
There are even some oils that use a mixture of mineral oil and synthetic oil.

So there is no strong reason to drain the entire lubrication system when changing oil types.

Myth No. 5
Synthetic oil will cause leaks if used on old machines.

SYNTHETIC OIL has smaller molecules than mineral oil so that it can pass through cracks in the seal.

Fact
The cause of oil leakage on old machines is because the seal has hardened.

Indeed, leakage is often seen when making oil changes, but actually the leak is caused by the detergent content in the new oil (either mineral oil or synthetic oil) dissolving the carbon crust which covers the seal gap and prevents leakage.
