Car oil
One of the most
important things I have is oils and filters
Today we gathered you
most of the good and bad
But first, we will
tell you some information about the oil
Because I remember a
lot that oil (heavy) is better than light oil, the oil is not 5000 and 10000 😉
● Oils are of two
types, mineral and synthetic 😏
Oh wait, I am from my
nation by telling you a piece of information, and I will explain to you exactly
the two in detail 😎
• metallic
It is an oil
extracted from petroleum after refining, and it is the oil that we have been
using for decades and purified to slight degrees without additives such as
15w40 or 20w50.
• synthetic
They are oils that
are manufactured and installed in chemical laboratories, and they are among the
best and finest oils, and they are divided into two types
100% synthetic and
half synthetic
It is an oil whose
chemical composition has been modified in laboratories to have properties
different from mineral oil and is produced by advanced refining processes with
a higher quality and purity than traditional mineral oils. It is not only pure
of impurities, but every part of its molecules is compatible with the
requirements of modern engines. These specially formulated molecules work to
provide the highest levels of protection and performance
100% synthetic like
0w30 or 5w30 or 5w40..
And the other
semi-synthetic, such as 10w40, which is a mixture of mineral oil and synthetic
oil. So that mineral oils do not exceed 30%
And its cost is less,
and it was produced before the full synthetic as a stage of development, and
then it was produced fully synthetic and became the best
Synthetic oil features:
Better chemical and
physical stability than mineral oil, it does not decompose or lose its
viscosity quickly.
It saves fuel
consumption because it helps the engine parts move more easily and reduces
friction to the maximum degree.
Maintains the motor
when the car is running in the morning (which is the period during which the highest
wear of the internal parts of the engine occurs because the oil is located at
the bottom of the oil sump - in the cartira - and when the oil starts to go up
to cover all the internal parts of the engine)..
In the case of
petroleum oil, its texture is heavy and takes time to reach the required
viscosity
However, synthetic
oil has a stable viscosity at low temperatures and at high temperatures, which
makes it reach more quickly than petroleum oil to the internal parts of the
engine, which reduces its wear and provides it with a longer life.
Higher flow velocity
than petroleum oil, which helps to carry out the lubrication process with
higher efficiency.
Lower evaporation
rate.
The German quality
control body "TUV Nord" explained
Synthetic oil has
better lubricating properties and temperature tolerance compared to mineral
oil.
The German authority
added that the expensive synthetic oil is produced by adding a group of
improved materials known as "additives".
While mineral oil is
cheap, it is mainly produced from refined oil.
These additives,
consisting of special hydrocarbons, keep the lubricating layer from
disintegrating when the engine is running at high as well as low temperatures.
For optimum
lubrication, or viscosity, synthetic oil is superior to mineral oil in engine
starting efficiency as well as at high engine loads.
It also has the
advantage of maintaining the engine and increasing the life span.
It should be noted
that without the lubricating layer in the engine oil, high heat will be
generated between the engine parts due to direct contact and friction.
This speeds up its
corrosion, and the oil acts as an anti-rust.
● As for the role of
oil, it is limited to lubricating and cooling the internal parts of the engine
and reducing the process of friction and wear.
Acceptable oil color
shades on the left
And the color grades
of the oils that need to be changed are on the right
● With regard to the
color of the oil mixed with water on the far right, this is evidence of damage
to the gasket and cylinder head, and the mixing of engine oil with coolant,
which is known as “milled” oil.
In this case, we need
to disassemble the cylinder, detect it, and change the damaged parts
- One of your friend
finds a ghost in himself like this 😂
He tells you, by the
way, this oil will run 5000 km, but it is better to change it better at 4000
km!!! Seconds of seconds 😨 Oh ghost, you will let
your friend throw his money into the ground in the first place!! Because this kilometer
is determined on the basis of the beginning of a deterioration in the
properties of the oil, which is scientifically not disturbing its functions. I
mean, the oil of the five will not be affected if you walk on it 5500 or 6000
and I am not saying that you do this, but I say your kilometers are normal and
worry.. ✋
- You find one of
your friend's friend above this and the ghost inside himself is like this 😂
he tells you that yellow(name) oil is better than red (name) oil!!! So, on what
basis did you decide this talk 🤔!!
I hope you don't compare the oil with the color of the jerrycan. You are the
one who is comparing the level of performance, because other than that, you are
unfair to the oil whose performance level is lower..
- You also find one of
your ghost friends. He tells you that this oil makes the sound of the motor
calmer and softer!!! Oh ghost, you and the motor, even when it is still new,
makes a specific noise in the decibel scale at every number of RPM laps 🔊
and I think the noise of it is a good indicator of the movement of the
mechanical parts properly. The sound of the motor and this is also more wrong,
because the oil in this case represents greater resistance to the mechanics of
the movement of the motor, exactly as if you used the gearbox oil for its wife
140 on the recommended gear with a viscosity of 80, you will find the gearbox
is very heavy.. 👇
● What is the meaning of 5w40
5 is the viscosity of
the oil in cold weather when the engine is running in winter
40 The viscosity of
the oil at a high temperature, that is, after the engine is running..
That is, the higher
the number is 30, 40, 50, 60, the better it is to keep the engine in high
degrees, i.e. 60 is better than 40.
The lower the 0w, 5w,
10w, 15w, 20w, the better when the engine is running at minimum temperatures..
as the oil reduces its viscosity whenever the number decreases, i.e. 0w is
better than 15w when the engine is running.. as the lighter the oil the easier
it is
