5 Things to Know about Oil Changes

Regular oil changes are crucial for maintaining the health and longevity of your vehicle's engine. Whether you're a seasoned car owner or new to the world of automotive maintenance, understanding the basics of oil changes can save you time, money, and potential headaches down the road.

Here are five essential things you need to know about oil changes.

From why oil changes are crucial routine maintenance to types of oil and the tell-tale signs your oil needs a change stat, every driver should be aware of these five facts about oil in a vehicle's engine.

1. Why Oil Changes are Important

Oil is the lifeblood of your vehicle's engine. It lubricates the moving parts, reduces friction, and helps keep the engine cool. Over time, oil breaks down and becomes contaminated with dirt, debris, and engine by-products. This can lead to increased engine wear, decreased performance, and even engine failure if not addressed. Regular oil changes ensure that your engine stays clean and well-lubricated, improving its efficiency and lifespan.

2. How Often to Change Your Oil

The frequency of oil changes depends on several factors, including the type of oil used, your driving habits, and the manufacturer's recommendations. Traditional wisdom suggested changing oil every 3,000 miles or every three months, whichever came first. However, advancements in oil technology and engine design have extended this interval for many vehicles. Today, many manufacturers recommend oil changes every 5,000 to 7,500 miles or every six months for newer vehicles on the road. Always consult your owner's manual for the most accurate information.

3. Types of Engine Oil

There are different types of engine oil available, each with its benefits and applications. The main categories include:

• Conventional Oil: This is the most basic type of oil, suitable for older, less complex engines. It is usually the most affordable option.
• Synthetic Oil: Designed for high-performance and modern engines, synthetic oil offers superior protection and performance. It is more resistant to breakdown and can last longer between changes.
• Synthetic Blend Oil: A mix of conventional and synthetic oils, synthetic blends offer a balance between performance and cost. They provide better protection than conventional oil without the higher price of full synthetic.
• High-Mileage Oil: Formulated for vehicles with over 75,000 miles, high-mileage oil contains additives that help reduce oil consumption, leaks, and engine wear.

4. Signs That You Need an Oil Change

While adhering to the manufacturer's recommended oil change intervals is crucial, it's also important to be aware of signs that your vehicle might need an oil change sooner. These include: 

• Dark, Dirty Oil: Fresh oil is amber in color and slightly translucent. As it gets used, it becomes darker and dirtier.
• Engine Noise: If you notice increased engine noise or knocking sounds, it might indicate that the oil isn't lubricating engine parts effectively.
• Oil Change or Check Engine Light: Many modern vehicles are equipped with oil change indicator lights that alert you when it's time for a change. The check engine light can also indicate low oil levels or issues with the oil quality.
• Exhaust Smoke: Blue or dark exhaust smoke can signal oil burning within the engine, indicating the need for an oil change or possible engine repair.
• Oil Smell Inside the Car: A strong smell of oil inside the cabin can indicate an oil leak or an issue with the oil system.
   

5. DIY vs. Professional Oil Changes

Changing your oil yourself can be a cost-effective and satisfying task if you have the right tools and knowledge. However, it can be messy and time-consuming. On the other hand, professional oil changes offer convenience and ensure the job is done correctly. Vehicle technicians also perform additional checks, such as inspecting the oil filter, checking fluid levels, and looking for potential issues.
