Mercon V vs Mercon LV Transmission Fluid

Like most car owners, you probably stick with the transmission fluid that your car came with. But did you know that there are different types of transmission fluid? And that each class is designed for a specific purpose? This blog post will discuss the difference between Mercon V and Mercon LV transmission fluids. We’ll also tell you which fluid is best for your car.

Why Compare?

Sometimes, we see there are a lot of products in a similar category and with similar specifications. In those cases, we get confused about which product is best and which one we should buy. We need to compare these two products to remove this confusion and worry.

Motorcraft MERCON V is a high-quality automatic transmission fluid recommended by Ford Motor Company for use in Ford, Lincoln, and Mercury vehicles. It is also recommended for use in vehicles manufactured by General Motors, Nissan, and Mazda.

MERCON V protects your car from getting worn down. It also keeps the inside of your vehicle clean and free from gum, sludge, lacquer, and foam. Plus, it protects the car against rust and corrosion as it is dyed red, so you can easily see if there is a leak.

Motorcraft MERCON LV is a high-quality automatic transmission fluid recommended by Ford Motor Company for use in Ford, Lincoln, and Mercury vehicles that require MERCON LV-type fluid. It also provides excellent performance in electronically controlled automatic transmissions.

Motorcraft MERCON LV is a high-quality transmission fluid used in various climates. The additives’ unique design helps provide smooth shifting, even in extreme conditions.


Mercon v stands for high and stable viscosity index. It provides consistent transmission even at low temperatures. It works well over a wide temperature range.

Mercon lv comes with low viscosity, providing less friction when the engine runs. It resists engines from instant heat and gets thick at high temperatures. It is slightly wider than Mercon v.

Thickness and Thinness

Mercon v is thinner than Mercon lv. It varies from low temperature to high temperature. So Mercon v fluid prevents internal resistance flow and abrasion more than Mercon Lv.

Overall performance

Mercon v fluid enhances anti-shudder protection for smooth shifting performance and keeps the engine clean from sticky mud and varnish build-up. Also, it keeps the engine clean after a long time.

In contrast, Mercon lv provides exceptional sludge resistance and excellent transmission life. It also offers superior oxidative fixity under all conditions.


You must flush the system first if you want to switch from Mercon V to Mercon LV in your Ford car. Mercon V is very similar to Dexron III and is compatible with Type H and Type CJ fluids. However, Mercon LV is not compatible with any other Mercon fluids or Mercon V. It is also consistent with older GM Dexron specifications.


MERCON V is an excellent hydraulic oil for various industrial applications requiring the ISO 46 or SAE 20W viscosity grade. In addition, MERCON V is also a high-quality ATF that can be used for certain power steering pump reservoirs. Another good option, Mercon LV, provides long service life and superb protection against abrasion and wear in specific situations.

What is Mercon V?

Mercon V is an automatic transmission and power steering fluid with a high viscosity index. High index viscosity allows the fluid to flow naturally but not quickly. Also, it is formulated to cover up the challenging demands of an automatic transmission environment and protects against slippage.

What is Mercon LV?

LV stands for low viscosity, allowing fluid to flow easily and swiftly. Mercon LV, also known as Valvoline Dexron VI, is a 100% synthetic automatic transmission fluid from first-quality materials.

It is the upgradeable ford ATF and is incompatible with recent Mercon fluids. It provides maximum performance and uses advanced additive technology.

What Do They Do?

Both are automatic transmission fluids (Primary lubricant) similar to engine oil. Since both oils come as automatic transmission fluid, they transmit and shift the engine to change the gear as soon as possible.

This transmission fluid is an oil and hydraulic fluid that facilitates gear shifts cools off the transmission, and lubricates all moving parts.

Our Observation

The main difference between Mercon V and Mercon LV is viscosity grade. Mercon V has a higher viscosity than Mercon LV, which means it will provide better protection in hot climates. Mercon LV, on the other hand, is designed for use in colder climates.

If you live in an area with extreme temperatures, you may consider using a higher viscosity transmission fluid. For example, Mercon V would be a good choice if you live in a hot climate. If you live in a cold climate, Mercon LV would be a better choice. After comparing both the products, we think Motorcraft MERCON V is a better product. The main reason is that it can be used in a variety of different climates and it also protects your car from getting worn down.
