The engine oil plays a crucial role in the smooth functioning of an internal combustion engine. It lubricates the moving parts, prevents corrosion, and helps to regulate the engine temperature. However, the viscosity of the engine oil is a critical factor that affects its performance. Thicker engine oil, also known as high-viscosity oil, is designed to provide better lubrication and wear protection in extreme temperatures. But when to use thicker engine oil? In this blog post, we will explore the importance of using thicker engine oil and the situations where it is recommended.

Importance of Thicker Engine Oil
Thicker engine oil, also known as high-viscosity oil, is designed to provide better lubrication and wear protection in extreme temperatures. It is thicker and more viscous than regular engine oil, which makes it more suitable for engines that operate in harsh conditions. Thicker engine oil is essential for engines that are subjected to high temperatures, heavy loads, or high-performance driving.
Thicker engine oil provides several benefits, including:
- Improved lubrication: Thicker engine oil provides better lubrication, which reduces wear and tear on moving parts.
- Better wear protection: Thicker engine oil helps to protect the engine from wear and tear caused by friction and heat.
- Improved fuel efficiency: Thicker engine oil can help to improve fuel efficiency by reducing friction and wear on moving parts.
- Longer engine life: Thicker engine oil can help to extend the life of the engine by reducing wear and tear.
Situations Where Thicker Engine Oil is Recommended
Thicker engine oil is recommended in the following situations:
Extreme Temperatures
Thicker engine oil is essential for engines that operate in extreme temperatures. In hot temperatures, thinner engine oil can break down and lose its lubricating properties, leading to increased wear and tear on moving parts. In cold temperatures, thinner engine oil can become too thick and difficult to pump, leading to poor engine performance.
Thicker engine oil is recommended for engines that operate in the following temperature ranges:
| Temperature Range | Viscosity |
|---|---|
| -20°C to 30°C (-4°F to 86°F) | 5W-30 or 5W-40 |
| 30°C to 40°C (86°F to 104°F) | 10W-30 or 10W-40 |
| 40°C to 50°C (104°F to 122°F) | 15W-30 or 15W-40 |
Heavy Loads
Thicker engine oil is recommended for engines that are subjected to heavy loads. Heavy loads can cause the engine to produce more heat, which can lead to increased wear and tear on moving parts. Thicker engine oil helps to reduce friction and wear on moving parts, making it essential for engines that are subjected to heavy loads.
Thicker engine oil is recommended for engines that are used for: (See Also: How to Tell if Car Has No Oil? Signs of Engine Trouble)

- Off-road driving
High-Performance Driving
Thicker engine oil is recommended for engines that are used for high-performance driving. High-performance driving can cause the engine to produce more heat, which can lead to increased wear and tear on moving parts. Thicker engine oil helps to reduce friction and wear on moving parts, making it essential for engines that are used for high-performance driving.
Thicker engine oil is recommended for engines that are used for:
- Racing
- High-performance driving
- Track driving
Choosing the Right Thicker Engine Oil
Choosing the right thicker engine oil is essential to ensure that your engine runs smoothly and efficiently. Here are some tips to help you choose the right thicker engine oil:
Check the Viscosity
The viscosity of the engine oil is critical to its performance. Thicker engine oil has a higher viscosity than regular engine oil. Check the viscosity of the engine oil by looking at the label on the bottle. The viscosity is usually indicated by a number, such as 5W-30 or 10W-40.
The first number in the viscosity rating indicates the oil’s cold-weather performance, while the second number indicates its hot-weather performance. For example, a 5W-30 oil has a lower viscosity in cold temperatures than a 10W-30 oil, but a higher viscosity in hot temperatures.
