What is multi grade oil? Multi Grade oil has the ability of the oil to
flow under cold and hot conditions mainly due to modifier additives being added.
In technical terms we call it viscosity
of the lube oil. Viscosity is the liquidity of the oil to flow measurement. A
higher viscosity means that the oil is thicker and the flow of such
oil will be slower, in other words it is less fluidity. In older days oil are graded by SAE 20, 30, 40, 50, 60 these are Traditional Lubricant
made from crude oil. Now days we see "API" more often.
API stand for American Petroleum Institute. With the improvement in car engine
technology now days, special lube oil is need especially for temperate climate country during
winter season as temperature could drops to -10 degrees, does causing the lube
oil to be frozen. Therefore the multi
grade oil comes into the pictures. The initial "W" stand for winter in
which the viscosity of the could with stand the winter temperature. Lets take an example say 5W40 lube oil, in this
case, the viscosity of the oil to flow during winter temperature is
at 5, while the second digit "40" indicates the oil
viscosity is at 40 under normal engine running temperature.
Using the right type of lube oil and grade
are very important to your car. Not all lube oil are created equal. Be aware that using the
wrong type and grade of Lube Oil, will cause serious damage to your engine,
gear box and other mechanical parts. The best solution is to find an
experience Car technician or Service Advisor who is well verse with
the specification requirement of your car's manufacturer. It may cost you a couple
of dollars more, but Prevention is
Better then Cure.
Mineral Lube Oil
These are Traditional Lubricant
made from crude oil during the process of oil refinery which had
been used for decade. It
consist more then 90% of natural base oil which are complex
mixtures of naturally Hydrocarbons.
Semi Synthetic Lube Oil
Semi Synthetic oils (also called "synthetic blend")
are mixture/blends of
mineral oil and with no more then 30% of synthetic oil.
Designed to have many benefits of synthetic oil without
matching the cost of pure synthetic oil. (human
made oil which consist of either polyalphaolefins "PAO"
& Ester, Polyalklene Glycols "PAG", Phosphate
Esters, Silicate Ester,Ionic Fluids)
Fully Synthetic Lube Oil
Fully synthetic Lube Oil are
Human scientifically made Lubricant using chemically modified petroleum
components rather then whole crude oil or other raw material.
Synthetic oil is used as substitute for lubricant refined from
petroleum which when operating in extreme of temperatures mainly due to its superior in its
mechanical and chemical properties
than those found in the traditional mineral oil.
Recycle Lube Oil
These are Lube oil made from
used lube oil collected from garage and filtered & refined with chemical
additives been added & blended with some virgin oil base
stock. This lubricant are the cheapest synthetic
in the market and are marketed in many brands locally. I used to
name it as budget synthetic lube oil and personally do not
recommended them to my
customer even though it is cheaper, useless requested.
The technical advantages of synthetic motor oils include:
1. Measurably better low- and high-temperature viscosity performance at
service temperature extremes
2. Better chemical & shear stability
3. Decreased evaporative loss
4. Resistance to oxidation, thermal breakdown, and problems
drain intervals with the environmental benefit of less oil
fuel economy in certain engine configurations.
lubrication during extreme cold weather starts
7. Longer engine life
protection against and other deposit
formation in engine hot spots (in particular in
turbochargers and superchargers) for less oil burn off and
reduced chances of damaging oil passageway clogging.
horsepower and torque due to less initial drag on engine
10. Does not contain detergents
possesses the following characteristics:
