The Properties of Engine Oil

Engine oil primarily consists of base oils which are enhanced and modified with the various kinds of dispersants, detergents and oxidation inhibitors. While its primary use is for the lubrication of an engine due to a need arising from the friction created within, engine oil has come a long way in recent years ranging in different grades and viscosity. Fuel is known to generate a certain acid when burnt and engine oil possesses the properties to counteract this from further damaging your engine. The base oil which is the foundation of the lubricant is usually comprised of petroleum-based hydrocarbons which are organic making them sought out by most vehicle owners due to the fact that these oils are usually environmentally friendly.

Let’s Talk Some Chemistry

Those base oils are derived from crude oil, they are made into a thicker form of petroleum hydrocarbon which essentially creates a lubricating film between parts and minimizes damage to components of your engine as a result of parts frequently coming into contact with each other. An important element contributing to this film is the lubricant’s viscosity. In simple terms the viscosity of a liquid would refer to its thickness and it is absolutely crucial that engine oils maintain the right balance in this consistency. The viscosity must be thick enough to create a film to serve its purpose and thin enough so that the oil can be freely distributed to all components of your engine. The thickness of the lubricant would obviously be affected by the heat generated within the engine however there is a measure to check how responsive the oil is to a change in temperature and this measure is called the viscosity index. In simple terms higher the viscosity index the lesser responsive it is to fluctuations in temperature.

Flash Point

The flash point is a measure of the lowest point in which an engine oil gives off vapours that are flammable and easy to ignite. From a safety perspective this is important as a low flash point can result in an unwanted fire igniting in the engine which could be potentially life-threatening. High-grade engine oils like Penrite Oil have a high flashpoint which makes it quite safe to use. Even this is a quality that should be looked at when considering purchasing an engine oil. Most oils are produced through fractional distillation which removes the most volatile components of the oil making them essentially less conducive to fire.

Factors to Consider

There are many factors to consider when choosing the right Engine oil and it is for you to decide on the viscosity, grade and brand etc. Reputed brands in the engine oil market are reputed for a reason. They have earned the confidence of a majority of the users in the market and are renowned for their quality and functionality, these high-grade engine oils would always be a good choice to make when purchasing the right engine oil for your vehicle. Do your research and get the best for your vehicle, proper maintenance of your engine can save up a lot of time and money for you.
