What is Motor Oil?
Many of us knows that our car needs an oil change at a specific time interval or after driving a specific distance but many of us do not know what our motor oil does for our car. So what is motor oil?
If we compare a car to a human then a car’s motor is a human’s heart, while its oil is like blood. Without the two, both human and car are useless. As we humans have many different blood types so do motor oils whereby, LIQUI MOLY East Malaysia offers oils tailored to suit each vehicle precisely.
Liqui Moly's main product is motor oil with Molybdenum Disulfide, also known as MoS2, is widely used as a solid lubricant due to its low frictional properties even with increasing load. It also provides engine protection against wear, oxidation and corrosion. It can be added to motor oils and to non-motor oils including gear oil, transmission oil or differential oils. From this additive, an entire range was developed, with over 4000 products including engine and gear oils, additives and vehicle care products, workshop equipment and service products. This additive gave rise to the company name LIQUI MOLY and brought about our vast range of products that is available in 110 countries, thus catering to every need in the automotive industry.
Motor oil comes in different bases such as fully synthetic, synthesis technology, semi-synthetic and mineral-based. A fully synthetic oil base generally will be better for racing or very high performance applications. Due to the wide range of engine types, emissions standards and viscosity ratings come to show that synthetic oils are the industry’s standard for being reasonably priced and easily tailored to suit products.
Meanwhile, a synthesis technology based oil is known as low-friction motor oil. The combination of non-conventional base oils and modern additive technology reduces the friction inside the engine to a minimum and ensures maximum engine performance as well as low fuel consumption.
A semi-synthetic end product still has mineral oil as its base. Whereby, a mineral base oil is the most basic form of engine oil. It is made in the refinery after being distilled from crude oil and due to the basic nature, its technical properties are limited, meaning it is more suited to older style engines using more traditional materials and lower stressed components.
Almost every lubricant used today consists of a base oil. Normally, lubricants consist of 90% base oil and 10% additives. The American Petroleum Institute (API) has categorized base oils into five categories which are specified by the saturate level, sulfur level, and viscosity index.
Groups I, II, and III are derived from crude oil (mineral oil), Group IV is a fully synthetic oil, and Group V is for all base oils that are not included in one of the other groups. Before all the additives are added to the mixture, lubricating oils begin as one or more of these five API groups.
Group I base oils are solvent-refined, which is a simpler refining process, making them the least refined and therefore also the cheapest base oils available. Solvent-refined oils consist commonly of a mix of different hydrocarbon molecules which cannot be distinguished in the refining process. This results in an oil with irregular molecules causing increased friction within the oil. Group I oils are therefore used most often in less demanding applications.
Group II base oils are defined as being more than 90 percent saturates, less than 0.03 percent sulfur and with a viscosity index of 80 to 120. They are often manufactured by hydro-cracking, which is a more complicated process than the process for Group I oils. Hydro-cracking is a process that breaks down large hydrocarbon molecules into smaller ones. The hydrocarbon molecules of these oils are saturated, giving them better anti-oxidation properties. Group II oils are priced closely to Group I oils. They also have a clearer color and cost more in comparison to Group I base oils. Still, Group II base oils are becoming very common on the market today and are priced very close to Group I oils.
Group III base oils undergo an even longer process than Group II oils. The process, called severe hydro-cracking (higher pressure and heat), is also more intense. More pressure and heat is applied during the refinery process. This longer process is designed to achieve a purer base oil. Even though Group III oils are derived from crude oil, they are sometimes described as synthesized hydrocarbons.
Group IV base oils are polyalphaolefins (PAOs). These synthetic base oils are made through a process called synthesizing. They are not extracted but made from small uniform molecules. This is also the biggest advantage of PAOs because they can be completely tailored to have a structure with predictable properties. They are very suitable for use in extreme cold or extreme hot conditions.
Group V base oils are classified as all other base oils, including silicone, phosphate ester, polyalkylene glycol (PAG), polyolester, biolubes, etc. If it is a synthetic oil and it is not PAO it is a group V base oil. They include, among others, of naphthenic oils and esters. Usually Group V oils are not used as a base oil but as an additive to other base oils.
