Understanding Gear Oil
Gear oil, also known as transmission fluid, is a type of lubricant designed to reduce friction and wear on moving parts within a vehicle’s transmission and gearbox. It’s a critical component of any vehicle’s maintenance routine, as it helps to prevent damage to the transmission and gearbox components. Gear oil comes in various viscosities, which are measured in centistokes (cSt) or viscosity index (VI). The most common viscosities for gear oil are 75W-90, 80W-90, and 85W-140.
Synthetic Gear Oil
Synthetic gear oil is a type of oil that’s designed to provide superior performance and protection for high-performance vehicles and applications. It’s made from chemical compounds that are designed to mimic the properties of natural oil, but with improved thermal stability, viscosity index, and shear stability. Synthetic gear oil is often used in high-performance vehicles, racing cars, and heavy-duty trucks, as it provides better lubrication and protection in extreme temperatures and conditions.
Benefits of Synthetic Gear Oil
- Improved lubrication and wear protection
- Better thermal stability and resistance to breakdown
- Improved viscosity index and shear stability
- Reduced oil consumption and emissions
- Improved fuel efficiency and performance
Conventional Gear Oil
Conventional gear oil, also known as mineral-based gear oil, is a type of oil that’s made from refined petroleum products. It’s designed to provide basic lubrication and protection for standard vehicles and applications. Conventional gear oil is often used in passenger vehicles, SUVs, and light-duty trucks, as it provides adequate lubrication and protection in normal driving conditions.
Benefits of Conventional Gear Oil
- Cost-effective and affordable
- Provides basic lubrication and protection
- Suitable for standard vehicles and applications
- Easy to find and replace
- Less expensive than synthetic gear oil
Can You Mix Synthetic and Conventional Gear Oil?
The short answer is yes, you can mix synthetic and conventional gear oil, but it’s not always recommended. Mixing the two types of oil can provide some benefits, such as improved lubrication and protection, but it can also lead to some drawbacks, such as reduced performance and increased wear on components. Here are some pros and cons to consider: (See Also: Should You Run Your Car Before Changing Oil? The Ultimate Guide)

How to Mix Synthetic and Conventional Gear Oil
If you decide to mix synthetic and conventional gear oil, it’s essential to follow the correct blend ratio and guidelines. Here are some tips to help you get started:
Blending Ratio and Guidelines
| Blend Ratio | Synthetic Oil | Conventional Oil |
|---|---|---|
| 50/50 | 50% synthetic oil | 50% conventional oil |
| 75/25 | 75% synthetic oil | 25% conventional oil |
| 25/75 | 25% synthetic oil | 75% conventional oil |
Conclusion
Mixing synthetic and conventional gear oil can be a viable option in certain situations, but it’s essential to understand the pros and cons and follow the correct blend ratio and guidelines. Remember that synthetic gear oil provides superior performance and protection, while conventional gear oil is cost-effective and suitable for standard vehicles and applications. By understanding the properties and characteristics of each type of oil, you can make an informed decision about whether to mix synthetic and conventional gear oil and how to do it effectively.
