As car owners, we’re always looking for ways to extend the life of our vehicles and keep them running smoothly. One common debate among car enthusiasts is whether to use thicker oil with high mileage cars. This topic has sparked a lot of controversy, with some arguing that thicker oil is the best option, while others claim it’s unnecessary and even detrimental to the car’s performance. In this article, we’ll delve into the world of oil viscosity and explore the pros and cons of using thicker oil with high mileage cars.

The Importance of Oil Viscosity
Oil viscosity is a critical component of a car’s engine, playing a vital role in lubricating moving parts, cooling the engine, and cleaning the engine’s surfaces. Viscosity refers to the oil’s thickness or flowability, with thinner oils being more suitable for high-performance engines and thicker oils being better suited for older engines or those with high mileage.
There are several types of oil viscosity, including:
| Viscosity Grade | Description |
|---|---|
| 0W-20 | Thinner oil suitable for high-performance engines |
| 5W-30 | Medium-thickness oil suitable for most passenger vehicles |
| 10W-40 | Thicker oil suitable for older engines or those with high mileage |
The Case for Thicker Oil with High Mileage Cars
Proponents of thicker oil with high mileage cars argue that it provides several benefits, including:
- Improved lubrication: Thicker oil can better lubricate worn engine components, reducing friction and wear.
- Increased engine protection: Thicker oil can provide better protection against engine corrosion and damage caused by high mileage driving.
- Better cold-start performance: Thicker oil can help improve cold-start performance by providing better lubrication and reducing engine noise.
However, there are also some potential drawbacks to using thicker oil with high mileage cars, including: (See Also: Is Motor Oil Hazmat? The Surprising Truth)
- Increased fuel consumption: Thicker oil can increase fuel consumption, which can be a concern for drivers who prioritize fuel efficiency.
- Reduced engine performance: Thicker oil can reduce engine performance, particularly in high-performance vehicles.
- Potential for increased engine wear: Thicker oil can actually increase engine wear if it’s not compatible with the engine’s specifications.
The Case Against Thicker Oil with High Mileage Cars
Opponents of thicker oil with high mileage cars argue that it’s unnecessary and can even be detrimental to the car’s performance. They point out that:
- Thicker oil can increase engine wear: Using thicker oil than recommended can increase engine wear and potentially lead to premature engine failure.
- Thicker oil can reduce fuel efficiency: Thicker oil can increase fuel consumption, which can be a concern for drivers who prioritize fuel efficiency.
- Thicker oil can affect engine performance: Thicker oil can reduce engine performance, particularly in high-performance vehicles.
Additionally, some argue that using thicker oil with high mileage cars can mask underlying engine problems, rather than addressing the root cause of the issue.
What’s the Best Option for High Mileage Cars?
So, what’s the best option for high mileage cars? The answer depends on several factors, including the car’s make and model, driving conditions, and maintenance history. Here are some general guidelines:
- Check the owner’s manual: The best place to start is by consulting the owner’s manual, which will provide guidance on the recommended oil viscosity for your specific vehicle.
- Consider the car’s age and mileage: If your car is older or has high mileage, you may want to consider using a thicker oil to provide extra lubrication and protection.
- Monitor the car’s performance: Keep an eye on the car’s performance and adjust the oil viscosity accordingly. If the car is experiencing issues, such as increased engine noise or decreased performance, you may need to adjust the oil viscosity.
Conclusion
In conclusion, the decision to use thicker oil with high mileage cars is not a straightforward one. While thicker oil can provide some benefits, such as improved lubrication and increased engine protection, it’s not necessarily the best option for every high mileage car. By considering the car’s make and model, driving conditions, and maintenance history, you can make an informed decision about the best oil viscosity for your vehicle. Remember to always consult the owner’s manual and monitor the car’s performance to ensure the best possible results.

FAQs
Q: Is thicker oil always better for high mileage cars?
A: No, thicker oil is not always better for high mileage cars. In fact, using thicker oil than recommended can increase engine wear and potentially lead to premature engine failure.
Q: Can I use thicker oil with a high-performance engine?
A: No, it’s generally not recommended to use thicker oil with a high-performance engine. Thicker oil can reduce engine performance and increase fuel consumption.
Q: How often should I change my oil?
A: The frequency of oil changes depends on several factors, including the car’s make and model, driving conditions, and maintenance history. It’s generally recommended to change the oil every 5,000 to 7,500 miles, but this can vary depending on your specific vehicle.
Q: Can I use synthetic oil with my high mileage car?
A: Yes, synthetic oil can be used with high mileage cars. Synthetic oil provides better lubrication and protection than conventional oil, making it a good option for high mileage cars. (See Also: What Does Engine Sound Like With Low Oil? – Warning Signs)
