In this buying guide, I will share my knowledge and experience with this type of gear oil to help you make an informed decision.

What is 75W140 Synthetic Gear Oil?

Synthetic gear oil is a lubricant made from artificially produced chemical compounds. It has superior thermal stability compared to conventional mineral-based oils. The numbers in 75W140 represent its viscosity, which determines its flow and thickness. This type of gear oil has a high viscosity rating, making it suitable for heavy-duty vehicles and extreme weather conditions.

Why Choose 75W140 Synthetic Gear Oil?

  • Improved Performance: The synthetic composition of this gear oil provides better lubrication, resulting in improved performance and smoother operation of your vehicle’s gears.
  • Extended Drain Interval: Synthetic oils have a longer lifespan than mineral-based oils, meaning you can go longer between oil changes, saving you time and money.
  • Better Fuel Economy: Due to its superior lubrication properties, synthetic gear oil reduces friction between moving parts, resulting in better fuel efficiency.
  • Cold Weather Performance: The “W” in 75W140 stands for winter grade. This indicates that this type of gear oil can perform well even in cold temperatures.

Finding the Right Brand

The market is flooded with different brands offering 75W140 synthetic gear oil. Here are some factors to consider when choosing the right brand for your vehicle:

  • Certification: Look for brands that meet industry standards such as API (American Petroleum Institute) or SAE (Society of Automotive Engineers). These certifications indicate that the product has been tested and approved for use in vehicles.
  • Additives: Synthetic gear oils often come with additives that improve their performance. Look for brands that offer additives such as anti-wear agents, corrosion inhibitors and extreme pressure agents.
  • User Reviews: Read reviews from other car owners who have used the brand you are considering. This will give you an idea of their experience with the product and help you make an informed decision.

Tips for Using 75W140 Synthetic Gear Oil

  • Check Your Vehicle’s Manual: Before using any type of gear oil, it is essential to consult your vehicle’s manual to ensure it is suitable for your specific make and model.
  • Cleanliness:Synthetic oils are more sensitive to contamination than conventional oils. It is crucial to clean any dirt or debris from the area before pouring in the new oil.
