Understanding Engine Oils: A Detailed Guide to Types of Motor Oils

Engine oil plays a vital role in ensuring the smooth operation and longevity of your vehicle's engine. However, with the multitude of options available on the market, it can be challenging to determine which type of oil is best suited for your car. In this comprehensive guide, we'll explore the various types of motor oils in detail, including their compositions, viscosity ratings, and applications, to help you make an informed decision.

1. Conventional Motor Oil:Description: Conventional motor oil, also known as mineral oil, is derived from crude oil through a refining process. It is the most basic type of engine oil and is commonly used in older vehicles or those with low-mileage engines.Viscosity Grades: Typically available in single-grade (e.g., SAE 30) or multi-grade (e.g., 10W-30) viscosity ratings.Applications: Suitable for everyday driving conditions and moderate engine temperatures.
