Selecting the right engine oil is crucial for ensuring the longevity and efficiency of your vehicle's engine. It's not just about pouring any oil into the engine; it's about choosing the one that meets the specific requirements outlined by the manufacturer.
When it comes to selecting engine oil, it's essential to refer to the specifications provided by the company. These specifications are designed to ensure compatibility with your vehicle's engine and its components. Ignoring these recommendations can lead to poor engine performance, increased wear and tear, and even potential damage.
For instance, if you own a Toyota Yaris, it's recommended to use 5W-30 engine oil, as specified by Toyota. This particular grade of oil offers the right viscosity and additives to protect the engine under various operating conditions, including cold starts and high temperatures.
Attachments are for understanding & selection criteria of engine oil. Please note that starting number shows the minimum temperature during cold start (In Karachi temp. never goes below 5 degree) in addition to that last digit shows the viscosity of oil i.e. once engine completes it's cold start cycle. therefore don't go with additional science engine comes with many parts with different metallurgy and there is engineering team behind who recommends oil based on metallurgy.
Note: Just follow the manufacture specs and take any brand but original (Better if it's fully synthetic) . No need to go with fancy imported oil.
