Tips on choosing a car oil


Choosing the engine oil is sometimes quite confusing, because of ignorance of the specification we will use oil. An understanding of the conditions of operation of the machine used, as well as knowledge about the specifications of oil, could help solve this problem of anxiety.

As is well known that the engine oil is a very important role for example, reduce the coefficient of friction between the machine elements intersect, a cooling agent in the engine room, to avoid rust, make sure to avoid wearing on the surface of the element and so on.

In addition to the above requirements they will be the engine oil when the engine operates, always be in an environment that has a high temperature due to the combustion process in the combustion chamber. The combustion process they will also cause oxidation and lead to Radicals, or compounds which usually arise due to the reaction heat effect, thus causing degradation of engine oil. To maintain the quality of oil from the reaction of oxidation-preventing additive required.

Besides the blow-by gas that is entering the combustion gases to the engine room containing the fuel does not burn completely, are likely to be soot or particulete, to avoid such particulate clumping so that it becomes its own problems, engine oil additives will also need the anti-forming clumps. In addition to the diesel engine, which allows the sulfur contained quite a lot then for this type of engine oil additives require neutralizing sulfur.

As it is known that elements such as engine piston-ring and cylinder-liner, connecting rod tip, then the cam-nose and rocker-arm is touching. For this section, lubrication of the fluid that is flowing into the lubrication surface where the flow is very limited. Condition of existing types of lubrication in the engine room they will be, should respond to one type of engine oil only.

For lubrication type of surface they will be, a high-viscosity engine oil would be better suited to protect from the elements wearing, but the high viscosity of engine oil that they will become an obstacle to the rotating elements which lowers the fuel efficiency of the system itself. Conversely a low viscosity or thin, good for fuel efficiency, but allows higher engine element of damage caused by the possibility of friction between the larger elements. So that engine oil needs in the conditioning to be able to respond to the type of lubrication is required as above. For example with the addition of additives ZDTP to protect the parts that intersect like the cam and so on.

Distribution of energy use combustion products can be described more or less energy can be used as a power system 25% of motion, friction wheels and the road 6% and 7.5% loss due to mechanical, from the distribution for example, by using engine oil SHG mechanical loss becomes 0% though, fuel efficiency will go up 7.5%, but actually can not expect such a high increase in fuel efficiency. But oil prices are suitable for high fuel efficiency, it is not so different from regular oil, then use the oil to enhance fuel keiritan it remains one point that is not forgotten.

Specifications to save fuel oil includes a variety of important things to remember. As explained above that there is some kind of lubrication that occurs in the engine room, in summary a good oil is oil that is able to reduce friction on the lubrication of any kind on top. In oil market, there is a certificate issued by ILAC standards, ie standards issued by the oil producers and automobile manufacturers regarding tsb-grade oil.

The trend today is the engine oil viscosity reduction in oil to lower the barrier fluid in a rotating element, while to deal with problems on the surface of the elements that intersect added additive anti-wearing, and so on. In operation in the field more in mild or moderate load conditions, with temperatures around 150 degrees centigrade, which has a base oil of the polymer has advantages. This is because the oil with the base polymer viscosity little changed despite the change in temperature is large enough. So that real applications have a wider range of usability or flexible. But with a low viscosity, or oil that is more dilute, have a higher tendency to evaporate from the oil with high viscosity. It has also become one of the themes of research on the formula-development engine oil.

Code of an engine oil viscosity, is usually written out of cans of oil. The part which is W, a viscosity index they will be tested with testing system Cold Cranking Simulator (CCS) is performed at low temperatures below zero, for example 10W, 20W, 5W or 0W. The smaller the number on it they will increasingly dilute the engine oil. Or the easier the engine starter. But when viewed in its specific usage problems in Indonesia and not in the highlands, the oil without the standard CCS is also sufficient. If the viscosity sign they will be, do not use the letter W, then the oil they will be only in the test with the standard at a temperature of 100 degrees C. The smaller the number, the more dilute, suited to the emphasis on fuel effisiency, but less well to protect the machine elements that are touching each other.

So really from a technical standpoint, for areas that do not meet the cold temperature, is sufficient to see oil specification with code numbers without the letter W. But in real usage back to the user satisfaction, whether using double standards, or simply by a single standard without testing CCS.

Long Life Engine Oil
With increasing attention to environmental issues, efforts to use the engine oil up to 30.000 miles now been started by some oil producers. This is in addition to a lighter burden on the environment also reduces the themes in the care of the machine. From the research it is known that the main cause of damage to the oil starts from reduced anti-oxidant additives in the oil. The decrease in anti-oxidation additives are causing damage to the compound base oil oxidation due to chemical processes, which carry a chain effect with other additives damage that accelerates exponentially increase the viscosity of engine oil. It is also known that the location of the cause of damage to the engine oil quality, generally starting from the part between the piston and cylinder.

The use of oil in the oil quality has been damaged condition will result in the dirt that accumulated in the machine. This debris comes from the oil itself is biodegradable, and clumping that could eventually be found in elements of the machine. So to solve this problem the use of anti-oxidant additives, detergent additives and clot-preventing additive to be one important key in determining the formula for the new engine oil.

But as a "rule of thumb", until recently, using an ordinary oil but is often replaced more secure than using a good oil but it is rarely replaced.

In outline, engine oil, there are five groups (according to the Standard API)

GROUP I: Mineral Oil with a sufficiently large impurity
GROUP II: Mineral oil with impurity less than Group I
GROUP III: Mineral Oil with Group II with a viscosity index greater.
GROUP IV: PAO (PolyAlphaOlefin) Synthetic Oil
GROUP V: esters Synthetic Oil

Group III is made with synthetic technology - called Synthetized Mineral Oil. Performed by Castrol Synthetic Label and sell at a price of course Synthetic Oil.

Today almost all synthetic oil they follow the lower grade and sell Castrol Synthetic Oil (hem, reap more profit).

Without seeing the type and quality of oil used, the problem is that there is fuel in the combustion chamber is not completely evaporated, so not everything is on fire. Residual fuel oil and blowby will wet the Ring piston and cylinder wall, so that the oil dissolves dry, until the friction between the piston rings to cylinder walls resist nobody, easily damaged.

Point is primarily how to make fuel is introduced into the combustion chamber is vaporized (approaching 100%), so that complete combustion will occur.
