When it comes to maintaining the health and longevity of your vehicle’s engine, choosing the right motor oil is crucial. One of the most important factors to consider is the viscosity of the oil, which is measured in terms of its thickness or flowability. But which motor oil is thicker? This is a question that has puzzled many car owners and enthusiasts, and the answer is not as simple as it seems. In this article, we will delve into the world of motor oil viscosity and explore the different types of oil, their characteristics, and how to choose the right one for your vehicle.

Understanding Motor Oil Viscosity
Motor oil viscosity is a measure of its resistance to flow, with thicker oils being more resistant to flow and thinner oils being more prone to flow. Viscosity is measured in units of centistokes (cSt) or Saybolt Universal Seconds (SUS). The Society of Automotive Engineers (SAE) has established a system of viscosity grades for motor oils, ranging from 0W to 60W. The “W” stands for “winter,” and the number represents the oil’s viscosity at low temperatures.
The Importance of Viscosity
Viscosity plays a critical role in the performance and longevity of your vehicle’s engine. Thicker oils provide better lubrication and protection at high temperatures, while thinner oils are better suited for cold temperatures. The ideal viscosity for your vehicle will depend on factors such as the type of engine, driving conditions, and climate.
Types of Motor Oil
There are several types of motor oil, each with its own unique characteristics and uses. The main types of motor oil are:
- Conventional Motor Oil: This is the most common type of motor oil and is suitable for most passenger vehicles.
- Synthetic Motor Oil: This type of oil is designed for high-performance engines and provides better lubrication and protection at extreme temperatures.
- Synthetic Blend Motor Oil: This type of oil is a blend of conventional and synthetic oil and provides a balance of performance and price.
- Full Synthetic Motor Oil: This type of oil is designed for high-performance engines and provides better lubrication and protection at extreme temperatures.
- High Mileage Motor Oil: This type of oil is designed for vehicles with high mileage and provides additional wear protection and seal conditioners.
- Diesel Motor Oil: This type of oil is designed for diesel engines and provides better lubrication and protection at high temperatures.
Viscosity Ratings
Motor oils have different viscosity ratings, which are measured in units of centistokes (cSt) or Saybolt Universal Seconds (SUS). The most common viscosity ratings are: (See Also: How Often Does Valvoline Recommended Oil Change? For Your Vehicle)
| Viscosity Rating | Description |
|---|---|
| 0W-20 | Thin oil for cold temperatures |
| 5W-30 | Medium oil for most passenger vehicles |
| 10W-40 | Thick oil for high-performance engines |
| 20W-50 | Thick oil for diesel engines |
Which Motor Oil is Thicker?
Now that we have covered the basics of motor oil viscosity and types, let’s answer the question: which motor oil is thicker? The answer is that thicker oils have higher viscosity ratings. For example, 20W-50 oil is thicker than 5W-30 oil. Thicker oils are better suited for high-performance engines, diesel engines, and vehicles that operate in extreme temperatures.
Choosing the Right Oil
Choosing the right motor oil for your vehicle is crucial for its performance and longevity. Here are some tips to help you choose the right oil:
- Check your owner’s manual: The best place to start is by checking your owner’s manual for the recommended oil viscosity.
- Consider your driving conditions: If you drive in extreme temperatures or have a high-performance engine, you may need a thicker oil.
- Consider your vehicle’s age: If your vehicle is older, you may need a thicker oil to provide additional wear protection.
- Consult with a mechanic: If you are unsure about which oil to use, consult with a mechanic or oil change professional.
Conclusion
In conclusion, choosing the right motor oil is crucial for the performance and longevity of your vehicle’s engine. Understanding motor oil viscosity and the different types of oil available is essential for making an informed decision. By considering your driving conditions, vehicle’s age, and consulting with a mechanic, you can choose the right oil for your vehicle. Remember, thicker oils are better suited for high-performance engines, diesel engines, and vehicles that operate in extreme temperatures.

FAQs
What is the best motor oil for my vehicle?
The best motor oil for your vehicle will depend on factors such as the type of engine, driving conditions, and climate. It is recommended to check your owner’s manual or consult with a mechanic to determine the best oil for your vehicle.
Can I use synthetic oil in my conventional engine?
Yes, synthetic oil can be used in conventional engines, but it is not necessary. Synthetic oil is designed for high-performance engines and provides better lubrication and protection at extreme temperatures. Conventional oil is sufficient for most passenger vehicles.
How often should I change my motor oil?
The frequency of oil changes depends on the type of oil used and the driving conditions. It is recommended to check your owner’s manual or consult with a mechanic to determine the best oil change schedule for your vehicle.
Can I mix different types of motor oil?
No, it is not recommended to mix different types of motor oil. Each type of oil has its own unique characteristics and is designed for specific engines and driving conditions. Mixing different types of oil can compromise its performance and potentially damage your engine. (See Also: Who Makes Kirkland Synthetic Motor Oil? Revealed)
What is the difference between conventional and synthetic oil?
Conventional oil is refined from crude oil and is suitable for most passenger vehicles. Synthetic oil is designed for high-performance engines and provides better lubrication and protection at extreme temperatures. Synthetic oil is more expensive than conventional oil but provides better performance and protection for your engine.
