![]() ![]() Synthetic oil, as the name implies, is a synthetic base oil artificially created in laboratories to optimize lubricity while addressing the chemical and thermal instability characteristic of mineral oil. ![]() As such, mineral oil-based engine oils, though cheaper to manufacture and purchase, need to be changed more frequently. However, having been refined from a crude oil, one of the disadvantages of mineral oil is that it’s very difficult to completely remove sulfur impurities.Īlso, compared to synthetic oils, mineral oil is more chemically unstable, its viscosity at high temperatures is low and it more easily carbonizes introducing sludge. Only after refinement can the oil then perform the most basic of engine oil needs – lubrication. As a result, fewer products using those oils remain in production.Įngine oil made from mineral oil is first refined to remove impurities. However, their chemically unstable nature as well as their reaction to heat, means naphthenic and aromatic oils can easily oxidize. Naphthenic and aromatic oil have a double covalent bond which allows them to have good solubility. Paraffinic oil can be used as a base for a lubricant because its chemical structure contains lubricity and is chemically stable like paraffin used for making candles. The main components of mineral oils are paraffinic oil, naphthenic oil and aromatic oil. Mineral oils are the lubricating base oil produced by refining heavy crude oil, produced as a secondary product in the process of refining crude oil into petroleum products such as petrol and diesel. Let’s compare the two engine oils and find out what. Although, it‘s true that synthetic engine oils do have many advantages over mineral engine oils, mineral engine oils, in turn, also have their specific benefits. For this reason, many drivers believe that to protect the car’s engine and withstand the most extreme conditions, it’s better to choose a more advanced synthetic product. Is a high-quality engine oil always good?Īs 80-90% of engine oil is base oil, the quality of engine oils varies greatly depending on the characteristics of the base oil. As such, how the base oil was created, not the amount of additives added, determines whether an engine oil is considered mineral or synthetic. If, however, synthetic oil made artificially from chemical synthesis is used as the base oil, it’s classified as synthetic engine oil. If mineral oil refined from the crude oil is used as the base oil, it’s classified as a mineral oil. ![]() What then is the basis for classifying synthetic and mineral engine oils? The answer is related to which oil was used to create it. However, both synthetic and mineral engine oils are composed of 80-90% base oil with performance boosting additives for anti-wear, anti-oxidation and anti-friction. Many people think that the difference between synthetic engine oils and mineral engine oils is the existence or absence of additives. Let’s find out what make synthetic and mineral engine oil different. The best way to decide is to learn the differences yourself and weigh the pros and cons of the two engine oil types. With so many arguments for either option, it can get to be very confusing. What’s the difference between mineral engine oil and synthetic engine oil, and which one is right for you? It’s a question many car owners have likely considered before. ![]()
