Gear Oil vs. Transmission Fluid: What’s the Difference?
There are a variety of different fluids used in cars and other motorized vehicles, and it can be confusing to know which one to use. The two most common types of engine fluids are gear oil and transmission fluid, and understanding the difference between the two is important for proper maintenance of your vehicle.
What is Gear Oil?
Gear oil is a type of lubricant specifically formulated for manual transmissions and power steering systems. It is made from mineral or synthetic oil with special additives, and it is thicker and heavier than transmission fluid. Gear oil is used to reduce friction and heat in the gearbox and steering components, and it is designed to last longer than conventional engine oil.
What is Transmission Fluid?
Transmission fluid is a type of lubricant used in automatic transmissions, transfer cases, and some other components in the powertrain. It is typically made from a combination of mineral and synthetic base oils with certain additives designed to reduce frictional wear and increase transmission efficiency. Transmission fluid is much thinner than gear oil, and it is designed to lubricate and cool the internal components of an automatic transmission.
Are Gear Oil and Transmission Fluid the Same?
No, gear oil and transmission fluid are not the same. While both fluids are used to lubricate and protect the internal components of a car’s engine, they are formulated differently and intended for different uses. Gear oil is thicker and heavier than transmission fluid, and is typically heavier duty and designed for manual transmissions and power steering systems. Transmission fluid is thinner, and is specifically formulated for use in automatic transmissions.
It is important to understand the difference between gear oil and transmission fluid in order to properly care for your vehicle. Gear oil is thicker and designed specifically for manual transmissions and power steering systems, while transmission fluid is thinner and made for automatic transmissions. Knowing which type of fluid you need for your car’s components is the key to keeping your vehicle running smoothly.
