The importance of motor oil in the maintenance of a vehicle cannot be overstated. It plays a crucial role in lubricating the engine, reducing friction, and preventing wear and tear on moving parts. However, one of the most common questions that car owners have is how long unused motor oil is good for. This is a crucial question, as using old or expired motor oil can lead to serious damage to the engine and potentially even render it inoperable.
Motor oil is a complex blend of chemicals designed to provide specific benefits to the engine. It is formulated to meet the unique demands of different vehicles, driving conditions, and environmental factors. When motor oil is new, it is designed to provide optimal performance and protection to the engine. However, over time, the oil’s properties can break down, making it less effective and potentially even harmful to the engine.
