A few extra dollars spent on fresh oil can save you money in the long run and help extend the life of your vehicle.

Engine lubrication

Oil Breakdown

Motor oil, or engine oil, is designed to provide lubrication for the numerous moving parts inside an engine. As the engine runs, these parts generate significant friction, leading to extreme heat. While fresh oil serves as an effective lubricant, over time, it undergoes a process of oxidation, becoming thicker and sludgy. This breakdown can be accelerated by various factors, including salty air from the ocean, dust from dirt roads, and even the weather. Old oil with a higher viscosity demands more effort from the engine to circulate, resulting in increased fuel consumption.

Friction and Wear

The absence of proper lubrication between metal parts can have detrimental effects on engine performance and fuel economy. Without a clean layer of oil, these parts grind against each other, generating substantial friction. This friction not only leads to increased fuel usage but also causes engine wear and potential damage. Regular oil changes help prevent this issue by ensuring a clean, thin layer of oil is maintained, allowing the engine to operate with minimal resistance.

Dirt and Debris

In addition to the natural breakdown of oil, it also accumulates dirt and debris over time. These contaminants further reduce the oil's ability to lubricate effectively. Regular oil changes help remove these particles, ensuring the oil can continue to provide optimal lubrication. This is particularly important for vehicles operating in harsh environments or those that frequently drive on dirt roads.

Clogging

Old motor oil doesn't just hinder lubrication; it can also lead to clogging issues within the engine. Sludge-like particles in the oil can build up on vital components, such as filters and spark plugs. This clogging impedes the normal functioning of these parts, impacting fuel vapour movement and combustion. Consequently, the engine's fuel efficiency decreases, and excess fuel is consumed. Regular oil changes prevent this buildup, ensuring vital components remain clear and functioning optimally.

Benefits of Regular Oil Changes

The benefits of maintaining proper engine lubrication through regular oil changes are significant. Firstly, you can achieve optimal fuel economy, as fresh oil reduces friction and allows the engine to operate more efficiently. Secondly, regular oil changes help lower the overall cost of ownership by reducing the likelihood of costly engine repairs due to excessive wear or damage. Additionally, studies have shown that engines with fresh oil produce fewer pollutants, contributing to cleaner air. Finally, by reducing wear and tear on engine components, regular oil changes can extend the lifespan of your vehicle.

Engine cooling

The engine cooling system, which includes the radiator, coolant, and associated components, is responsible for maintaining the engine's operating temperature within an optimal range. This system helps prevent engine overheating, ensuring efficient combustion and minimizing engine wear.

When engine oil is not changed regularly, it can lose its cooling properties, leading to increased engine temperatures. This can cause the engine cooling system to work harder to maintain the optimal temperature range, reducing its efficiency and increasing fuel consumption.

Additionally, old or degraded engine oil may not effectively lubricate the engine's moving parts, leading to increased friction and heat generation. This additional heat can further impact the engine cooling system, requiring more coolant flow and fan operation to maintain temperature. As a result, the engine may experience reduced fuel mileage due to the increased effort required to overcome the higher friction and heat levels.

To maintain optimal engine cooling and fuel mileage, it is essential to adhere to the recommended engine oil change intervals.
