As a car owner, one of the most important maintenance tasks you can perform on your vehicle is regular oil changes. This simple yet crucial task can significantly extend the life of your car, improve its performance, and even save you money in the long run. However, when it comes to high mileage cars, the question of how often to change the oil becomes even more pressing. In this comprehensive guide, we’ll delve into the world of high mileage cars, explore the importance of regular oil changes, and provide you with expert advice on how often to change the oil in your high mileage vehicle.
Understanding High Mileage Cars
A high mileage car is typically defined as a vehicle that has exceeded 75,000 miles on the odometer. At this stage, the engine has undergone significant wear and tear, and the engine oil has been subjected to intense heat and friction. As a result, the oil’s viscosity and lubricating properties may begin to degrade, leading to decreased engine performance and potentially causing damage to the engine.
High mileage cars often require more frequent oil changes to compensate for the increased wear and tear on the engine. The type of oil used in high mileage cars is also crucial, as it must be able to withstand the high temperatures and pressures generated by the engine. Synthetic oil, for example, is a popular choice for high mileage cars due to its superior lubricating properties and ability to withstand extreme temperatures.
The Importance of Regular Oil Changes
Regular oil changes are essential for maintaining the health and longevity of your car’s engine. Engine oil plays a critical role in lubricating the moving parts of the engine, reducing friction and wear, and preventing corrosion. Over time, the oil’s lubricating properties can break down, leading to increased engine noise, decreased performance, and potentially causing damage to the engine.
The American Automobile Association (AAA) recommends that drivers change their oil every 5,000 to 7,500 miles, depending on the type of vehicle and driving conditions. However, for high mileage cars, it’s often recommended to change the oil more frequently, typically every 3,000 to 5,000 miles. This is because the engine is subjected to increased stress and wear, which can cause the oil to break down more quickly.
Factors Affecting Oil Change Intervals
Several factors can affect the frequency of oil changes in high mileage cars. These include:
- Turbocharged engines: Turbocharged engines produce more heat and stress on the engine oil, requiring more frequent changes.
- Severe driving conditions: Driving in extreme temperatures, towing heavy loads, or driving in stop-and-go traffic can all increase the wear and tear on the engine oil.
- High-performance engines: High-performance engines often require more frequent oil changes due to the increased stress and heat generated by the engine.
- Age of the vehicle: As a vehicle ages, the engine oil may break down more quickly, requiring more frequent changes.
Oil Change Intervals for High Mileage Cars
The frequency of oil changes for high mileage cars can vary depending on the type of vehicle and driving conditions. Here are some general guidelines:
- Every 3,000 to 5,000 miles: For high mileage cars with turbocharged engines, severe driving conditions, or high-performance engines.
- Every 5,000 to 7,500 miles: For high mileage cars with normal driving conditions and no severe driving conditions.
- Every 10,000 miles: For high mileage cars with very mild driving conditions and no severe driving conditions.

How to Check Your Oil
Checking your oil is a simple process that can help you determine if it’s time for an oil change. Here’s how to do it:
1. Make sure your car is parked on a level surface and turned off.
2. Locate the oil dipstick under the hood of your car. It’s usually labeled “Oil” or have an oil can symbol on it.
3. Pull out the dipstick and wipe it clean with a lint-free rag or paper towel.
4. Insert the dipstick back into the oil reservoir and pull it out again. The dipstick will now be coated with oil.
5. Check the oil level by looking at the end of the dipstick. The oil level should be between the “MIN” and “MAX” marks on the dipstick. (See Also: How to Change Engine Oil at Home? A DIY Guide)

- Oil light on your dashboard: If the oil light on your dashboard is illuminated, it’s a sign that the oil level is low or the oil is dirty.
- Oil leak: If you notice oil leaking from your car, it’s a sign that the engine is damaged and needs to be repaired.
- Engine noise: If your engine is making unusual noises, such as knocking or clunking sounds, it may be a sign that the oil is dirty and needs to be changed.
- Decreased fuel efficiency: If your car’s fuel efficiency has decreased, it may be a sign that the oil is dirty and needs to be changed.
- Engine overheating: If your engine is overheating, it may be a sign that the oil is dirty and needs to be changed.
