Reasons To Change Oil When We Buy Cars In South Africa

So you buy a car and decide to give it a little service especially since you don't know what the previous owner was up to.


What oil do you use and what should you put in your engine with your new oil filter?

Check your Oil

The identification 20W50 refers specifically to the viscosity of motor oil. This refers to its fluidity or thickness. The "20W" indicates how quickly the engine will start when cold or in cold weather. The "50" refers to the thickness of the oil when the motor has been running for a while. 20W50 motor oil is relatively viscous and thick. Most modern oils are 10W40 or even 5W40.

Thicker oils are more suited to warmer climates while thinner oils such as 5w40 is better suited for colder climates. This does not mean that it can’t be used as some manufacturers actually specify high quality thinner oils sometimes known as synthetic type oils. 

So in simple terms use the higher number in warmer climates and the lower number in colder climates. This does not apply in all cases and some manufacturers require that you use specific oils and viscosity grades in their engines, sometimes caused by Hydraulic systems that are pretty fussy. Some engines suffer from a symptom known as hydraulic lifter noise and this can only be resolved with cleaning and maintained by using specific grades of Oil. Note your brand of oil filter will play a part in this.

Take note that... 

With 2019 global GDP estimated to be $86 trillion, the oil and gas drilling sector alone makes up around 3.8% of the global economy. The industry includes companies that specialize in crude petroleum production, the mining and extraction of oil from shale or sands and the recovery of hydrocarbon liquids.

Gasoline is a mixture of many different hydrogen and carbon containing chemicals

Chemicals include common inorganic salts, transition metal compounds, common organic chemicals and solvents, water-soluble and oil-soluble polymers, and surfactants.

Without oil the engine will seize and stop working so it is really important to keep levels correct, but hey don't overfill as this causes new issues so keep the level correct and remember your oil will get dirty and lose viscosity over time so frequent changes are just as important.
