No doubt at some point in time you may have heard the ongoing debate about which type of motor oil is best for your motor vehicle.
Functions of Motor Oil
Although the primary function of motor oils is to lubricate all the moving parts of the engine, it carries out a few other functions as well. Motor oils serve to keep the engine cool and provides protection against wear by reducing friction. It also prevents corrosion and keeps the engine free from small pieces of debris.
Conventional Motor Oil
Conventional motor oil has its origins in crude oil, which is pumped from the ground and is processed. A base oil is produced to which additives are added. This changes the properties of the liquid giving it protection properties, improved heat breakdown levels, and viscosity.
Synthetic Motor Oil
Unlike conventional motor oil the base oil of synthetic motor oil comprises artificial or synthesized components, thus its name. Like conventional motor oil however, additives are added to give it properties similar to those of conventional motor oil.
Differences Between Conventional and Synthetic Motor Oil
Although they both carry out the same functions both oils have significant differences in addition to having their pros and cons. Conventional motor oil contains minute amounts of wax, sulfur, and asphaltic material, which are by-products of its manufacturing process. Synthetic motor oil, on the other hand, because it is chemically produced, has none of these contaminants. Another difference between the two is that synthetic motor oils will flow at much lower temperatures making it preferable in harsh winter conditions. At these same low temperatures conventional motor oil would freeze. Being more consistent in size and shape, the molecules of synthetic motor oils better withstand extreme temperatures; hence it will take longer to break down under extreme heat than conventional motor oils. Synthetic motor oils have very low viscosity ratings and in some cases have been known to flow up to seven times faster than conventional motor oils. This comes in handy at engine start up time, as that is when the most engine wear is likely to occur.
Making Your Choice
In deciding on which motor oil you will be using there are other factors besides those already mentioned, which will have to be taken into account. One of these is the type of car that will be using the motor oil. A high performance racecar owner will obviously choose the synthetic motor oil, as that is the oil they were specifically made to use. Newer cars with smaller clearances will also lean towards synthetic motor oils. The cost of the motor oil will play a significant role in the decision on which oil to use too, as the cost of synthetic motor oil can be as much as four times that of conventional motor oil. If someone changes their car yearly they may say why bother towaste extra money on synthetic oil. The car’s age could also play a part as waxes and sludge build-up by conventional motor oil could mask worn engine seals. These could come to light with the introduction of synthetic motor oils, which tends to break down and clean away those build-ups, thus possibly causing leaks and creating problems.
