Why Synthetic Gear Lube 75W 90 is necessary?

I have been a car enthusiast for many years now and have learned the importance of using quality gear lubricants for optimal vehicle performance. One of the most essential lubricants for any vehicle is the gear lube, which helps to protect the gears and bearings from wear and tear. While there are many options available in the market, one that stands out for its superior performance is Synthetic Gear Lube 75W 90.

Firstly, synthetic gear lube is designed to withstand extreme temperatures and pressures, making it ideal for high-performance vehicles or those that regularly tow heavy loads. This type of lube has a higher viscosity index, meaning it maintains its thickness even at high temperatures, providing better protection to the gears. It also contains additives that prevent foaming and oxidation, ensuring smooth operation and extended life of the gears.

Moreover, synthetic gear lube has a longer service life compared to conventional mineral-based gear lubes. Due to its superior formulation, it can last up to three times longer than regular lubes, reducing the frequency of oil changes and saving both time and money in the long run. It also has excellent shear stability, meaning it maintains its viscosity under extreme pressure conditions

Introduction: As a car enthusiast, I understand the importance of using the right products for maintaining my vehicle. One essential product that I have recently come across is the Synthetic Gear Lube 75W 90. After extensive research and personal experience, I have put together this buying guide to help others make an informed decision when purchasing this product.

What is Synthetic Gear Lube 75W 90?

Synthetic gear lube 75W 90 is a type of lubricant specifically designed for manual transmissions, differentials, and transfer cases. It is made up of synthetic base oils and advanced additives that provide superior protection against wear and tear, extreme temperatures, and corrosion.

Why should I choose Synthetic Gear Lube 75W 90?

Synthetic gear lube 75W 90 offers numerous benefits over conventional gear oils. Firstly, it has a higher viscosity index, meaning it maintains its thickness in both high and low temperatures. This ensures smooth shifting and proper lubrication in all weather conditions. Additionally, synthetic gear lube has a longer life span compared to conventional oils, which means less frequent oil changes.

Things to consider before buying:

  • Type of vehicle: It is crucial to check if your vehicle manufacturer recommends using synthetic gear lube before making a purchase. Some vehicles may require specific types or viscosities of gear oil.
  • Versatility: If you own multiple vehicles with different transmission systems, you may want to consider purchasing a versatile synthetic gear lube that can be used in various applications.
  • Additive package: Look for synthetic gear lubes with advanced additive packages that offer additional protection against extreme pressure, oxidation, and corrosion.
  • Certifications: Check for industry certifications such as API (American Petroleum Institute) or GL (Gear Lubricant) ratings to ensure the quality and performance of the product.

Tips for using Synthetic Gear Lube 75W 90:

  • Cleanliness: Before adding new gear oil, make sure to clean the area around the fill plug thoroughly to prevent any contaminants from entering the system.
  • Filling procedure: Always follow the manufacturer’s instructions on how to fill your transmission or differential properly. Incorrect filling can lead to inadequate lubrication or overfilling, which can cause damage.
  • Mixing with other oils: It is not recommended to mix synthetic gear lubes with conventional oils as it may affect its performance and compromise its benefits. Always use a compatible oil when topping up or changing your gear oil.

In conclusion,

Synthetic Gear Lube 75W 90 is an excellent choice for those looking for superior protection and improved performance for their vehicle’s transmission system.
