Expert Advice: Should I Use Thicker Oil in a High Mileage Engine?

In the world of automotive maintenance, there are countless debates and discussions about the best practices for keeping your vehicle running smoothly. One question that often arises is whether or not it is beneficial to use thicker oil in a high mileage engine. To shed some light on this topic, we turned to industry experts and sought their advice.

Before delving into the experts’ opinions, let’s first clarify what is meant by “thicker oil” and “high mileage engine.” Thicker oil refers to a higher viscosity oil, which means it is more resistant to flow. On the other hand, a high mileage engine typically refers to an older vehicle with a significant number of miles on the odometer.

According to automotive experts, the decision to use thicker oil in a high mileage engine depends on several factors. One crucial consideration is the condition of the engine itself. If the engine is in good shape and does not exhibit any signs of excessive wear or oil consumption, sticking to the manufacturer’s recommended oil viscosity is generally the best course of action.

However, if your high mileage engine is experiencing oil leaks or burning oil, some experts suggest switching to a slightly thicker oil. The reasoning behind this recommendation is that a thicker oil can help reduce oil consumption and provide better lubrication to aging engine components. It is important to note that this should only be done after consulting with a trusted mechanic or following the manufacturer’s guidelines.

On the other hand, some experts caution against using thicker oil in high mileage engines. They argue that modern engines are designed to operate optimally with the recommended oil viscosity, and deviating from this specification may lead to decreased fuel efficiency and potential damage to engine components. It is worth noting that using oil with a higher viscosity than recommended can also cause issues during cold starts, as the thicker oil takes longer to circulate and lubricate the engine.

To make an informed decision, it is crucial to consult with a knowledgeable mechanic who can assess the specific needs of your high mileage engine. They will consider factors such as the engine’s condition, climate, and driving habits before recommending the most suitable oil viscosity.

In conclusion, the question of whether to use thicker oil in a high mileage engine does not have a one-size-fits-all answer. It is essential to consider the engine’s condition, consult with a trusted mechanic, and follow the manufacturer’s guidelines. Ultimately, the goal is to ensure proper lubrication and extend the life of your high mileage engine.
