Caution! What to Know Before Putting Conventional Oil in a High Mileage Car

As your car accumulates miles, it’s essential to maintain its health and performance with proper maintenance, including regular oil changes. However, the question of whether conventional oil is suitable for high mileage cars often arises. This blog post aims to provide a comprehensive guide on whether conventional oil can be used in high mileage cars and the factors to consider.

What is Conventional Oil?

Conventional oil is a petroleum-based lubricant commonly used in older vehicles with less than 75,000 miles. It is refined from crude oil and contains basic additives to enhance its lubricating properties.

Can I Put Conventional Oil in My High Mileage Car?

Yes, you can use conventional oil in high mileage cars under certain conditions. However, it’s important to consider the following factors:

1. Mileage

Conventional oil is generally recommended for vehicles with less than 75,000 miles. As your car accumulates more miles, the wear and tear on its engine parts increase, which may require a higher-quality oil.

2. Engine Condition

If your high mileage car’s engine is in good condition, with minimal wear and tear, conventional oil may be sufficient to provide adequate lubrication. However, if your engine has significant wear or leaks, a synthetic or high mileage oil blend may be a better choice.

3. Driving Habits

If you primarily engage in stop-and-go city driving or frequently tow heavy loads, your engine will generate more heat and stress. In such cases, synthetic or high mileage oil blends may provide better protection.

Benefits of Conventional Oil for High Mileage Cars

• Cost-effective: Conventional oil is generally less expensive than synthetic or high mileage oil blends.
• Adequate lubrication: If your high mileage car’s engine is in good condition, conventional oil can provide sufficient lubrication for everyday driving.
• Compatibility: Conventional oil is compatible with most vehicles, including older models.

Disadvantages of Conventional Oil for High Mileage Cars

• Shorter lifespan: Conventional oil breaks down faster than synthetic or high mileage oil blends, requiring more frequent oil changes.
• Reduced protection: As engines accumulate miles, they require higher-quality oil to protect against wear and tear. Conventional oil may not provide adequate protection for high mileage engines.
• Poor performance in extreme temperatures: Conventional oil may not perform well in extreme cold or hot conditions, which can affect engine performance.

When to Switch to High Mileage Oil

If you have a high mileage car and:

• Notice increased engine noise or vibration
• Experience oil leaks or consumption
• Drive in extreme temperatures or towing conditions
• Your engine has significant wear or tear

Wrap-Up: Making an Informed Decision

Whether conventional oil is suitable for your high mileage car depends on several factors, including mileage, engine condition, driving habits, and budget. If you have a high mileage car with a well-maintained engine and primarily engage in everyday driving, conventional oil may be an economical option. However, if your engine has significant wear or you have demanding driving needs, a synthetic or high mileage oil blend is recommended.
