The is one of the essential liquid needed by any in order to run smoothly, the major function of the is to lubricate the moving parts of the in order to reduce wear and tear caused by friction from the moving parts, as result of that the is always equipped with an inbuilt mechanism that helps the to be pumped from its reserve part in the known as oil sump to the other parts of the for the purpose of lubricating the .
Besides lubricating the , the also assists in the cooling of the parts during the reciprocating actions of the in the wall of the cylinder otherwise known as the chamber. The possibility of helping in the cooling and the percentage of the reduction completely depends on the type of the .
Most of the oils in the market were made to have high viscosity while some were made to have low viscosity, though many people attribute the quality of an to its viscosity but research in most bodies had shown otherwise, rather one should be more concern on the type of the oil is meant for and power output expected from such .
Most oils with low viscosity are seen as the quality types due to their appearance while the ones with high viscosity are always seen as bad due to the fact that they flow readily when pouring them into the but all those assumptions are wrong and those mostly using such criteria for determining the quality of an may be novice and lacked proper understanding of the working principle of an . The is good for a particular may become bad for another , it is all determined by the materials of the , its design, burning fuel or type of fuel, power output, the speed of the , etc.
The next criteria some people use in determining the quality which might be wrong is the color of the , some oils appear colorless just as water appear while some do have the thick color of blue, green, or any other color. The fact is that many refer to the colorless types as being more superior in quality than others attributing its colorless nature as an evidence of lack of impurities and a well-refined , while the colored types are seen with an opposite view. But the simple truth is that assumption could be wrong because some of the colored oils have some additives added inside which are meant to be of great help to the lifespan of the as well as increasing the duration in which the is meant to stay in the before it can be changed. While the assumption could be right when viewed with respect to the appearance condemned oils which do appear black or brown in color, some individuals who usually manipulate the markets could go to a local place and have the condemned oil refined and then added another additive and colored such that it can be difficult to notice that they are counterfeit, such people can insert the name of any brand to the and sell it to the market, such had damaged the reputation of most manufacturers, and such action is a very serious criminal offence in which are usually handled by industrial courts established by the federal government.
Nevertheless, the color or appearance of an has nothing to do with its quality and good or bad performance in any , rather it the contents of the additives and the that determines it alongside the type of it is used for.
However, the signs from the after the had been changed could show whether such oil is good for the or not, below are some of the signs:
CHANGE IN SOUND
When an is operating with a very loud sound it is an evidence of high frictional occurrences in the which are taking place without adequate , the major source of loud sounds from the are, the chamber of the , the reciprocating of and its rings on the wall of the cylinder, the bearings located at different places in the , and the exhaust cylinder of the , while the exhaust cylinder does not require any , the entire parts of the rest requires though the volume of oil required from each part may vary, because some part requires more oil than the other, the and its rings requires a good quantity of lubricating oil followed by the bearings, the chamber may not require any in it because its inclusion in the compressed air-fuel mixture would lead high release of carbon mono oxide which causes the to be producing thick black smoke from the exhaust hole for this reason is not needed in the chamber.
A sign that an is good for the is when the sound is able to reduce to a significant level after changing the , the reason for that is because the oil is able to penetrate into the various parts of the such that the friction in the moving parts is properly controlled. The presence of a good between the cylinder wall and will reduce the noise coming from that source. The presence of lubricating oil in the bearing of the crankshafts and other moving parts of the will also reduce the noise coming from that source. If an had stayed in an for a long period of time it would affect the viscosity of the and the might have accumulated so many particles from the wear and tear of the moving parts of the such that it becomes difficult for it to penetrate effectively into various parts of the , so a change in the of an would ensure the presence of the lubricating oil in various parts of the .
STABLE POWER OUTPUT
There are many factors that could cause the instability in the power of an such factors may include presence of bad , but it has been observed that bad and insufficient lubricating oil can also affect the power out of the and cause it to be fluctuating, this is common in the .
Hence, a good will make the power output to be stable after adding it inside the .
REDUCED CARBON MONO OXIDE OUTPUT
The excess smoke coming out of the hole of the exhaust is a result of excess carbon mono oxide released in the chamber when the occurs, the cause for this may be as a result of bad fuel in the or as a result of lubricating oil finding its way into the chamber, the factor that may give opportunity for this occurrence is bad or broken .
An that had been in the had accumulated so much dirt from the including carbon monoxides but the new one had no such particles hence, having it inside the would produce less smoke in the exhaust due to the non-carbon monoxide inclusion. Also, the viscosity of the has not been affected by the dirt therefore, the lubricating oil may not easily flow into the chamber even if the are bad.
PROLONGED LIFE OF
A good would help to prolong the life of the by ensuring that no dirt is pushed into the wall between the cylinder and the , so if the oil is it could affect the lifespan of the by causing excess wear and blocking the clearance in the wall with dirt of other metallic particles in the lubricating oil.
Vibrations are mostly caused by misalignments in the parts, most misalignments are caused by the prolonged wear and tear in the moving parts of the , an old may have no viscosity to remain in the created by the action of wear and tear in the while the is in operation, though the may be working properly but the oil may find it difficult to remain in such small spaces for a long time especially when the location is in vertical position, therefore to have a reduction in the vibration coming from the after changing the oil is a sign that the viscosity is good for the .
The high operating in the usually leads to overheating which can cause a sudden shut off the followed by some damages in most moving parts of the . It is a situation that any owner doesn’t want to encounter. The major reasons why operate at high are low or insufficient such as water, the wrong metallic material the was made from, insufficient or bad and overloading of the .
A good lubricating oil helps the to be controlled while in the operational stage.
