When Should I Get My First Oil Change? Expert Opinion

Car maintenance is crucial for the longevity and functionality of your vehicle. One of the most routine and essential maintenance activities is the oil change. Yet, for new car owners or those who’ve recently purchased a vehicle, the question often arises: when should I get my first oil change?

Why is It Important to Change Oil?

Firstly, let’s establish why oil changes are essential. The primary function of motor oil is to lubricate the engine’s moving parts, reducing friction and heat. Over time, oil breaks down due to high temperatures and accumulates contaminants, reducing its efficiency as a lubricant. Changing oil regularly ensures that your engine remains clean and runs smoothly.

When Should I Get My First Oil Change?

The timing for your first oil change depends on whether you have a new vehicle or a used one, the type of oil you’re using, and your driving habits. Here’s a breakdown:

1. Consult Your Owner’s Manual

Always consult your vehicle’s owner’s manual before relying on general advice or a mechanic’s suggestion. Manufacturers test their vehicles extensively and provide specific recommendations based on their findings. Typically, intervals range from every 3,000 miles to 10,000 miles, depending on the vehicle and oil type.

2. New Cars

A common misconception is that brand-new vehicles need their oil changed much sooner than later. This might have been the case decades ago due to residues left from the manufacturing process. However, today’s engines are built with more precision and often come filled with specially formulated break-in oils.

The recommended brand new car oil change is between 5,000 and 7,500 miles. Still, always refer to your owner’s manual to get the most accurate recommendation for the first oil change new car of a specific make and model.

3. Conventional vs. Synthetic Oil

There’s a considerable difference between conventional and synthetic oils:

  • Conventional Oil: Derived directly from crude oil, this type of oil may require changes every 3,000 to 5,000 miles.
  • Synthetic Oil: This is the chemically engineered oil that provides better lubrication at extreme temperatures and lasts longer. Most cars running on synthetic oil can go anywhere from 7,500 to 15,000 miles between changes. It’s pricier than conventional oil but offers better protection and extended intervals.

4. Driving Habits and Conditions

How and where you drive can significantly influence the frequency of oil changes:

  • Short Trips: If your car is mostly used for short trips (less than five miles), consider changing the oil more frequently. Short trips don’t allow the oil to fully heat up, which can cause moisture and contaminants to accumulate.
  • Harsh Conditions: Driving in extreme temperatures, towing heavy loads, or frequent stop-and-go traffic can strain your engine and its oil.
  • Dusty Areas: If you live or frequently drive in dusty areas, your oil and air filter might need more frequent attention.

5. Used Cars

If you’ve acquired a used vehicle and are uncertain about its maintenance history, performing an oil change soon might be a good idea for peace of mind. From there, you can set a regular maintenance schedule based on the car’s age, type, and your driving habits. We recommend changing oil for old cars every 3000 miles.

Can I Go 3 Months without an Oil Change?

Going 3 months without an oil change is generally acceptable for many modern vehicles, especially considering most manufacturers’ recommended intervals, which often span 5,000 to 10,000 miles or more. Factors like the type of oil used, primarily synthetic vs. conventional, play a significant role. Synthetic oils, with their advanced formulations, typically last longer and can easily extend beyond 3 months for average drivers.

However, it’s crucial to consider driving habits and conditions. Frequent short trips, extreme temperatures, or consistent heavy loads can impact oil longevity. Moreover, some older vehicles or those with high mileage might benefit from more frequent changes. Always consult your vehicle’s owner’s manual, monitor the oil’s condition using the dipstick and pour exact amount of oil. Regular maintenance, including timely oil changes, is key to your vehicle’s performance and longevity.

Is the First Oil Change the Most Important?

The first oil change is crucial but not necessarily the “most” important. Its significance is rooted in the following reasons:

  1. Engine Break-in Period: New engines undergo a break-in period where metal shavings and residues can enter the oil. The first oil change helps remove these contaminants, ensuring they don’t cause undue wear on engine components.
  2. Break-in Oil: Some manufacturers use special break-in oils for new engines. These oils contain additives that aid in the seating process of engine components, but they’re not intended for long-term use. The first oil change ensures the replacement of break-in oil with proper amount regular oil after the break-in period.
  3. Long-term Engine Health: Establishing a regular maintenance routine from the start can set the stage for the engine’s long-term health and performance.

However, it’s essential to understand that every oil change is vital. Regular oil changes, not just the first one, ensure that contaminants are removed, fresh additives are introduced, and the engine remains well-lubricated to prevent wear and maintain optimal performance.

Is It Bad to Change Oil Too Soon?

Changing oil too soon isn’t harmful to the vehicle but may not be cost-effective or environmentally prudent. Regular oil changes are crucial for engine longevity, but excessively early changes or too much oil can lead to unnecessary expenses and engine damage. Modern synthetic oils, designed to last longer, offer protection for extended periods. By changing them prematurely, you’re not maximizing their full potential, leading to wasted resources.

Frequent oil changes increase the environmental burden, as oil disposal contributes to ecological concerns. Moreover, overly frequent changes might overshadow other critical vehicle maintenance tasks that usually coincide with standard oil change intervals. While early oil changes won’t damage your engine, they may not be the most efficient use of resources or the best practice for overall vehicle care.


The new car first oil change is pivotal for ensuring the longevity and performance of your vehicle’s engine. While technology and oil quality have allowed for extended intervals between oil changes, it’s essential to strike a balance. This means being informed by the manufacturer’s guidelines and considering your unique driving habits and conditions. Regularly checking your oil level and color can also provide clues about its condition. When in doubt, it’s always best to consult with a trusted mechanic or service center.
