Types of Lubricant

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. 

Note: 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

These are 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.

Advantage of Synthetic

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 Extended drain intervals with the environmental benefit of less oil waste.
5. Improved fuel economy in certain engine configurations.
6. Better lubrication during extreme cold weather starts
7. Longer engine life
8. Superior 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.
9. Increased horsepower and torque due to less initial drag on engine
10. Does not contain detergents

Good lubricant possesses the following characteristics:

1. High boiling point.
2. Low freezing point.
3. High viscosity index
4. Thermal stability.
5. Corrosion prevention.
6. High resistance to oxidation

Donut Logo

The below donut logo stands for "API"- American Petroleum Industry and the current stand code is show with the red arrow "SN". SN series is for petrol/gasoline cars while "C" stand for commercial car/truck using diesel engine usage.
Can i use CJ4 for my passenger cars or SN series on Diesel engine? Visit Us
What does GL Mean? It stand for Gear Lubricant and they have rating from GL-1 to GL-5

Good Lubricant Contains the followings:

1. Anti-Oxidants
2. Detergents
3. Anti-wear
4. Metal de-activators
5. Corrosion Inhabitors
6. Rust Inhabitors
7. Friction Modifiers
8. Extreme Pressure
9. Anti-Foaming agents
10. Viscosity Index Improvers
11. Demulsifying/Emulsifying
12. Stickiness improver, provide adhesive property towards tool surface (in metalworking)
13. Complexing agent (in case of greases)
14. Active-Cleasing Agent
