Why Sae 140 Gear Oil is necessary?

As a car enthusiast and mechanic, I have learned the importance of using the right type of gear oil for vehicles. Sae 140 gear oil is one such type that is crucial for the proper functioning and longevity of a vehicle’s gears. In this article, I will share my personal experience and reasons for why Sae 140 gear oil is necessary.

Firstly, Sae 140 gear oil has a high viscosity, which means it is resistant to thinning at high temperatures. This is important because gears in vehicles operate at high speeds and temperatures. If the gear oil thins out, it will not provide sufficient lubrication to the gears, leading to increased friction and wear. This can ultimately result in damage to the gears and expensive repairs.

Furthermore, Sae 140 gear oil has excellent load-carrying capabilities. Gears in vehicles are subjected to heavy loads and pressures while transferring power from the engine to the wheels. The high viscosity of Sae 140 gear oil allows it to form a strong film between the gear teeth, preventing metal-to-metal contact and reducing wear.

Additionally, Sae 140 gear oil has good thermal stability, meaning it can withstand high temperatures without breaking

My Buying Guide on ‘Sae 140 Gear Oil’

I recently had to purchase Sae 140 gear oil for my car’s transmission and differential, and I learned a lot about this type of gear oil in the process. Here are some important things to keep in mind when buying Sae 140 gear oil.

What is Sae 140 Gear Oil?

Before purchasing any product, it’s important to understand what it is and how it works. Sae 140 gear oil is a type of lubricant specifically designed for high-pressure gears and bearings. It has a viscosity rating of 140, which means it can withstand extreme temperatures and pressures without breaking down. This makes it suitable for heavy-duty vehicles such as trucks, buses, and construction equipment.

Consider Your Vehicle’s Requirements

Not all vehicles require Sae 140 gear oil, so it’s essential to check your owner’s manual or consult with a mechanic before making a purchase. Some older vehicles may still use this type of gear oil, but newer models may have different requirements. Using the wrong type of gear oil can cause damage to your vehicle’s transmission and differential.

Check the API Rating

The American Petroleum Institute (API) sets standards for engine oils and gear oils. When purchasing Sae 140 gear oil, make sure it has an API rating of GL-5. This rating ensures that the gear oil meets the necessary requirements for high-pressure gears and bearings.

Look for Additives

Sae 140 gear oil often comes with additives that improve its performance. These additives can include anti-wear agents, extreme pressure agents, corrosion inhibitors, and friction modifiers. While these additives may increase the cost of the gear oil, they also provide additional benefits such as extending the life of your transmission and improving fuel efficiency.

Consider Synthetic vs Conventional

Synthetic SAE 140 gear oils are made from chemically engineered compounds that provide better performance in extreme temperatures and pressures compared to conventional oils. However, they are also more expensive. If you have a high-performance vehicle or regularly drive in harsh conditions, synthetic may be worth the investment. Otherwise, conventional SAE 140 gear oils should suffice.

Check for Warranty Approval

If you’re purchasing SAE 140 gear oil for a new vehicle under warranty, make sure to check if the brand you’re considering is approved by your car manufacturer. Using an unapproved brand could void your warranty.

Compare Prices

The price of SAE 140 gear oil can vary depending on brand, additives, and whether it’s synthetic or conventional. It’s always a good idea to compare prices from different brands or retailers to ensure you’re getting the best deal without sacrificing quality.

In Conclusion

Purchasing SAE 140 gear oil can be overwhelming with so many options available on the market. However, by considering your vehicle’s requirements, checking API ratings, looking for additives, comparing prices, and considering synthetic vs conventional options; you’ll be able to make an informed decision and choose the best SAE 140 gear oil for your vehicle’s needs.
