The importance of choosing the right oil
Choosing the right motor oil helps extend the life of your vehicle’s engine. This is because engine oil lubricates engine parts so they don’t grind against each other, which can lead to wear. Using the wrong oil will cause engine parts to be replaced in short periods.
Ensuring your engine’s optimal performance isn’t just about choosing the right oil, it also requires you to change your oil every 3,000 to 5,000 miles to keep your engine in top healthy condition. Changing the oil also helps keep the engine cool.
A regular oil change is essential and helps to avoid the problem of having dirty oil that is not effective for lubricating and cooling. Dirt and other foreign particles are regularly trapped in the oil, making it necessary to change and replace the used oil.
You can invalidate your warranty and disqualify your car from any repair or maintenance simply by choosing the wrong motor oil. Therefore, the importance of choosing the right motor oil for your car will decide whether or not you need to check and change your engine. This is more expensive than simply choosing the correct oil and changing it as needed.

Factor to consider when choosing your motor oil
Viscosity is the ease with which the liquid flows. The viscosity and the thickness of the oil are closely related. The thicker the motor oil, the more viscous it will be. On the other hand, a more dilute oil has a lower viscosity. 5w30 and 5w40 motor oils they have the number 5 which is then followed by W, which represents “winter.”
Therefore, 5W30 and 5W40 motor oils have the same viscosity in winter, which is 5 and moderately low. This simply indicates that the oils flow at very low temperatures but more easily through the engine. This is a good quality motor oil because a very viscous motor oil, such as 20w, will not flow as easily at low temperatures. This will prevent the oil from being distributed through the engine when it is cold, leading to engine wear and damage.

How the weather affects the type of motor oil
Climate and climate play an important role in determining the type of motor oil you use for your vehicle. Lower temperatures will require a lower viscosity. Oil flows easily through the system ensuring the engine is at peak performance. This is why both the 5W30 and 5W40 are suitable for cooler temperatures, unlike 10w or 20w oils.
However, high temperatures require slightly more viscosity …
