Choosing the engine oil is sometimes quite confusing, because of ignorance of specification oil that we will use. An understanding of the engine operating condition is used, as well as knowledge about the specifications of oil, can help solve this problem misgivings.
As is well known that the engine oil is a very important role as koeffisien minimize friction between the machine elements intersect, a cooling agent in the engine room, to avoid rust, make sure to avoid wearing on the surface element and so on.
In addition to the above requirements TSB engine oil when the engine operates, always in an environment of high temperature due to the combustion process in the combustion chamber. The combustion process they will also cause the oxidation reactions and cause Radicals, or compounds that typically arise due to reaction heat effect, thus causing degradation of engine oil TSB. To maintain the quality of the oil additive needed reaski TSB oxidation prevention.
Besides, blow-by gas which is a combustion gas into the engine room containing the fuel does not burn completely, tend to be soot or particulete, to avoid the particulate clot so that it becomes its own problems, engine oil additive also need anti-forming clumps of TSB. In addition to the diesel engine, which allows the sulfur contained quite a lot then this type of engine oil for neutralizing sulfur additive requires TSB.
As it is known that elements such as engines and piston-ring-cylinder liner, connecting rod tip, then the cam-nose and rocker-arm is touching each other. For such parts, 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 the type of surface lubrication TSB, the high viscosity engine oil would be better suited to protect from the elements wearing, but the high viscosity engine oil which 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 elemental damage caused friction between the possibility of larger elements. So that engine oil needs to be able to respond to the conditioning type of lubrication required as above. For example, by the addition of additives ZDTP to protect the parts that intersect like cam etc..
Distribution of energy use combustion products can be described more or less energy which can be used as 25% of system dynamics, friction wheels and the road 6%, and 7.5% loss due to mechanical, from the distribution of TSB for example by using a mechanical loss of engine oil SHG to 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 this remains one point which has not been forgotten.
Specifications of oil to save fuel they will include 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 above. In the oil is marketed, there is a standard certificate issued by ILAC, the standards issued by the oil producers and car manufacturers about the grade of oil TSB.
The trend today is the engine oil viscosity reduction in oil to reduce barriers to fluid on a rotating element, while to deal with problems on the surface of the elements that intersect added additive anti-wearing, etc.. On a more operational in the field much in the mild or moderate load conditions, with temperatures around 150 degrees Celsius, the oil which has a base of polymer has advantages. This is because the oil with a base polymer viscosity changes occurred despite little change in temperature is large enough. So that real applications have a wider range of usability or flexible. But with a low viscosity, or a more dilute oil, have a higher tendency to evaporate from the oil berkekentalan high. It has also become one of the themes of research on the formula-development engine oil.
The code of an engine oil viscosity, usually written out of oil cans. The part which is the letter W, is the viscosity index TSB were tested with test systems Cold Cranking Simulator (CCS) is performed at low temperature below zero, for example, 10W, 20W, 5W or 0W. The smaller the numbers on it the more dilute the engine oil TSB. Or the easier the engine starter. But when viewed in its specific usage problems in Indonesia and not in the highlands, the oil without CCS standards is also sufficient. If the viscosity TSB sign, do not use the letters 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, suitable for effisiency emphasis on fuel, but less well to protect the machine elements that are touching each other.
So actually from a technical standpoint, to Indonesia, which does not encounter cold temperatures,'ve seen enough oil specifications, 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, attempts to use the engine oil up to 30.000 km at this time has been started by some oil producers. This is in addition to a lighter burden on the environment also reduces the themes in engine maintenance. From the research it is known that the main cause of reduced damage to the oil begins anti-oxidation additives in the oil TSB. The decrease in anti-oxidation additives are causing damage to base oil compounds because the chemical process of oxidation, which took effect a chain with other additives damage that accelerates exponentially increases engine oil viscosity TSB. It is known also that the location of the cause of damage to the engine oil quality is, generally starting from the part between the piston and cylinder.
The use of oil in the damaged condition of the quality of this oil will lead to the emergence of the dirt that accumulated in TSB machine. This debris comes from the oil itself is biodegradable, and clumping which could eventually be found on the machine elements. So to solve this problem the use of anti-oxidation additives, detergents additives and clot-preventing additive to be one important key in determining the formula for a new engine oil.
But as the "rule of thumb", to date, using ordinary oil but it is often replaced more secure than using a good oil but it is rarely replaced.
In broad outline, there are five groups of engine oil (according to API Standard)
GROUP I: Mineral Oil with sufficiently large impurity
GROUP II: Mineral oil with less impurity than Group I
GROUP III: Mineral Oil as a Group II with a viscosity index greater.
GROUP IV: PAO (PolyAlphaOlefin) Synthetic Oil
GROUP V: Synthetic Oil esters
Group III is made with Synthetic technology - called Synthetized Mineral Oil. Performed by Castrol and sell it of course Label Synthetic Synthetic Oil prices.
Today almost all the lower grade synthetic oil and sell them to follow Castrol Synthetic Oil prices (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 evaporate, so not everything is on fire. Residual fuel oil and blowby will wet the piston ring and cylinder wall, so that the oil dissolves dry, until the friction between the piston rings to cylinder walls nobody restrain, fast AUS and BROKEN.
Main point how to make fuel that is inserted into the combustion chamber to evaporate (approaching 100%), so that complete combustion will occur, no residual fuel oil. A new artificial modern motorcycle , it still can not make perfect fuel evaporates in the combustion chamber (depending on the quality of fuel), even more so if there are event mixture Gasoline + Kerosene
, ..... machine will be broken or its performance will quickly become DEGRADATION
