Why do we need Motor Oil?

Sitting in the drivers seat for the very first time is daunting along with absolutely everything that you will have to learn about the vehicle you are sitting in too! When opening up the bonnet of the car  (which your Qualified Driving Instructor from Want Driving Lessons will do at some point with you during your driving lessons) everything will look completely confusing at first. What leads to where? What does that tank contain? And so on. It will take some time for you to completely get the hang of it all, but you will when shown by a qualified professional.

In this Blog post we will cover the importance of Motor Oil. First of all why do cars need oil? Motor Oil is also known in some countries as Engine Oil, it is used to lubricate all the various internal parts of any combustion engine (such as the one contained in the car you are driving). The main function is for the oil to cover the moving parts of the engines; as metal rubs against metal it produces a friction that erodes tiny particles of metal from both sides. In time a lot of damage can be caused on these parts. These particles will hopefully filter through the Oil Filters stopping any further damage from being done.

Oil also cleans out the engine along with its other jobs, while also preventing any corrosion from happening to them- as the metal parts are covered in oil they have little contact with oxygen, so they are ‘sealed’. The Engine Oil will also cool the friction caused by the moving parts by carrying the heat away, ensuring that there is no damage to your engine caused by over heating.

Here’s more of the Science bit: Motor and Engine Oils are taken from a Petroleum-based and also non-Petroleum-based synthesized chemical mixture. (Head hurting yet?) Modern Engine and Motor oils are blended from base oils composed of Hydrocarbons, Polyalphaolefins (PAO), and Polyinternal Olefins (PIO). These are entirely organic compounds made from Carbon and Hydrogen. Clever stuff! Motor Oil is specialist stuff so don’t try pouring Vegetable Oil or Extra Virgin Olive Oil into your cars! It won’t work and should be kept in the kitchen for those salads!

Engine Oil is essential in cars, vans, buses,basically any road worthy vehicle in order to keep their motors in good working order. Every car has a Oil tank and dipstick. The dipstick is normally attached to the lid and can be used to measure how much of the oil is left. It will indicate when you will have to top up your Oil supplies.

You should be able to see the ‘level’marking on the tank as you look underneath the bonnet of your car. You should be able to clearly see how much Oil to add for optimum performance.

There are several different brands of Engine Oil on the market, both Mineral Oils and Synthetic Oils with also ‘partly-synthetic’oil. It is best to find out from specialists at your local garage or a Motor Oil suppliers to find out more!
