Why I Use 10W-30 Conventional Motor Oil

As a car owner, I understand the importance of maintaining my vehicle’s engine to keep it running smoothly. One of the key factors in engine maintenance is choosing the right motor oil. After much research and personal experience, I have found that 10W-30 conventional motor oil is necessary for my car’s engine.

The “W” stands for winter, and a lower number before it means the oil will flow more easily in colder temperatures. This is important because during start-up, when the engine is cold, thick oil can cause damage by not circulating properly. On the other hand, a higher number after the “W” indicates that the oil will maintain its viscosity at higher temperatures. This ensures proper lubrication during hot weather or when driving long distances.

In addition to its viscosity rating, conventional motor oil has been tried and tested over many years and has proven to provide adequate protection for most engines. It contains additives that help clean and protect against wear and tear on engine parts. These additives also
