The Effects of Oil Oxidation on Engine Performance

When it comes to maintaining the performance and longevity of your engine, lubricating the engine’s moving parts is vital to reduce friction and prevent overheating. However, over time, engine oil becomes oxidized, which can affect how well your engine performs. In this blog, we’ll explore the effects of oil oxidation on engine performance and offer tips on how to manage this issue to keep your engine running smoothly. 

What Is Oil Oxidation?

Oil oxidation is the chemical reaction when engine oil reacts with oxygen. This process usually happens over time and is sped up by factors like high temperatures, prolonged use, and the presence of contaminants. As oil oxidizes, it forms acidic compounds and thickens, leading to several side effects on engine performance. 

Effects of Oil Oxidation on Engine Performance

Recognizing the effects of oil oxidation is essential to know how to prevent unnecessary wear and tear on engine performance. Let’s explore some effects of oil oxidation on engine performance: 

Increased Viscosity

As the engine oil thickens, it becomes less effective at lubricating engine components. This can lead to more friction and wear on engine parts.

Formation of Sludge and Deposits

Oxidized oil can break down into sludge and varnish-like deposits. These deposits can build up on critical engine parts, like pistons and valves. Sludge buildup can also block oil passages.

Reduced Oil Additive Effectiveness

Engine oils contain additives designed to protect against oxidation, corrosion, and wear. As oil oxidizes, these additives become depleted, which reduces their effectiveness. This can also reduce the engine oil’s ability to protect and lubricate the engine. 

Corrosion and Wear

The acidic compounds formed during oil oxidation can cause corrosion on metal engine parts. This can lead to increased wear and tear on the engine, reducing the engine’s lifespan and performance.

Increased Engine Temperature

Oxidized oil does not dissipate heat effectively. This means your engine may run at higher temperatures, causing it to overheat and adding stress on engine components.

How to Manage Oil Oxidation

Now that you know the effects of oil oxidation, here are some ways to manage it: 

Regular Oil Changes

Most manufacturers recommend changing the engine oil every 3,000 to 7,500 km, depending on the vehicle and driving conditions. Regular oil changes help make sure that fresh oil continues to protect and lubricate your engine.

Use High-Quality Oil

Choosing high-quality engine oil with advanced oxidation resistance properties can help reduce the effects of oil oxidation.

Monitor Oil Condition

Keeping an eye on the condition of your engine oil can help you catch signs of oxidation early. Regularly check the oil level and colour. If the oil appears dark and gritty, it may be time for an oil change. 

Address Engine Issues

If you have any performance issues, like increased engine noise or reduced power, have your vehicle looked at by a professional.
