Mercon V vs Mercon LV

Here is where it gets fascinating. An automatic transmission (AT) uses fluid inside the torque converter to transmit energy to move the vehicle under load. This can get quite complex, and there are many different types of ATF used in various gear or clutch systems and a wide range of viscosity levels.

And, each one is specially formulated for a specific application, depending on the superheat or sub-cooling of the fluid. It’s so fiddly that it almost doesn’t anyone. The following analysis brings you all information you need for a better performance of your vehicle.

Mercon V vs Mercon LV


Mercon LS is designed for professionals that require less viscosity (or thicker oil) in cold areas. Mercon LV is specially designed for countries that experience colder weather conditions, such as -30°C or below, and want an oil with thinner viscosity.


Mercon V is mainly designed for Ford transmissions. It is pretty similar to Dexron III, although there are some differences between them. Mercon V has excellent fluidity and protects the transmission from wear and damage. However, it does not perform as well as LV in higher temperatures.


Mercon V is a high-grade hydraulic oil with a viscosity of 46 or 20W that is perfect for use in applications that need medium-grade hydraulic oils. Likewise, Mercon V is the ideal choice for reservoirs of power steering pumps, where it offers superior protection against wear.

This product is recommended for automatic transmissions in automobiles, light-duty trucks, and off-highway vehicles. The automatic transmission fluids are essential to prevent many mechanic problems. Among the transmission, fluids are included type CJ fluid, and Mercon v. Mercon V is one of the better fluids than other options.

LV is the latest engineered, fully synthetic Ford automatic transmission fluid or Ford ATF. They are designed to meet the demands of environmental protection while delivering ultimate performance. LV is a fully synthetic ATF. LV has been specially formulated to ensure maximum fluid life and resistance to abrasion.


These fluids are highly rated and have been designed for all types of transmission.

What is Mercon V?

Mercon V is a lubricating fluid made with the highest technology synthetic base oils and an advanced additive package designed to meet the specifications and operating requirements of the most modern automatic transmissions. The Mercon V is a typical transmission fluid in Ford vehicles that replaced Dexron III. This article explains why Mercon V is an acceptable replacement for Ford Type F transmission fluid.

What is the best Automatic Transmission Fluid?

In the automotive industry, there are not only manual gearboxes but also automatic transmissions. For this type of transmission to work correctly, a special oil called ATF oil is needed. Certain aspects determine the quality of the oil, such as a high-pressure absorption capacity, an excellent viscosity-temperature ratio, high aging stability, a low foaming tendency, tolerance of all seal materials, etc.

Gearboxes that have been treated with unsuitable lubricants are more prone to breakdowns and problems, such as increased wear of plates and discs.

ATF automatic transmission oil must reduce friction to prevent wear (like all lubricants) and allow a certain level of friction for belt and clutch materials to engage smoothly without premature wear. Additionally, ATF hydraulic oil must be compatible with all transmission components, operate at extreme temperatures, and maintain consistent performance over extended periods.


What does Mercon LV stand for?

Mercon LV stands for Low Viscosity and is specially formulated to provide a low viscosity level, often ideal for low temperatures.

What is Dexron and Mercon?

Merken is a brand of products that have been available since 1987. Dexron was developed earlier and specialized in General Motors vehicles.

What is Mercon oil?

This oil is used as automatic transmission fluid and provides lubrication to modern automatic transmissions.

Types of ATF hydraulic oil


ATF type “A” oil was mainly used during the 1950s and therefore has the characteristics suited to the era’s models. It has little anti-rust power and does not offer much wear protection.


ATF type “F “oil is specially designed for Ford dealer and Jaguar models of the 1980s. It offers high resistance to oxidation and is specially designed for models with automatic transmission and power steering.


It was introduced to the market in the late 1960s as the successor to ATF Type-A oil. It was initially intended for vehicles with automatic transmission, but over the years, General Motors has been bringing out new versions and adapting them to other specifications.

Dexron VI

General Motors’ licenses for the use of Dexron III expired in 2005, at which point it only offers Dexron VI for its automatic models. It offers high thermal stability, works very well at low temperatures, and has excellent antioxidant power.


This is a fluid manufactured and released by Ford type in the late 1980s. It has supported some models of the Ford brand and some of its subsidiaries, such as Lincoln or the now-defunct Mercury.

Mercon V (“Mercon 5”)

An evolution of the Mercon, capable of supporting the most modern automatic gearboxes. Its significant advantages are its vibration resistance index and its ability to perform well at high and low temperatures.

ATF+3, ATF+4 (MS 7176 and MS 9602)

They are mainly used by Jeep, Chrysler, and Dodge. It is designed to extend clutch life, thanks to its lower coefficient of friction. It was introduced to the market to cover the deficiencies of Dexron II.


These are special ATF oils for Mitsubishi automatic transmissions. The use of Dexron or any other type of ATF oil in Mitsubishi models will significantly shorten the life of the transmission system.

Toyota WS (World Spec)

Its low viscosity characterizes this oil. It is designed for Toyota automatic models.

Oils for DSG double-clutch transmissions

The oil whose mission is to lubricate, actuate and cool the gearbox components is called DCTF. It is designed for automatic gearboxes in which the clutches are bathed in oil. 

Oils for Continuously Variable Transmission (CVT)

According to the transmission manufacturer, these transmissions allow maintaining the engine at its maximum torque converter, which can reduce consumption by up to 20%. This type of transmission needs to be treated with specific deficient friction oils. 

It should be emphasized that the proper use of these types of ATF oil is essential to take care of the engine and gearbox in cars with automatic transmissions, ensure their proper operation, and increase their service life.

The automatic trans fluid is ideal for vehicles with automatic gearboxes; they are generally red or green; these colors distinguish it from the engine oil and other vehicle fluids. Exist many newer fluids, like Valvoline Mercon, Valvoline Maxlife, Valvoline ATF, Dexron ii, Dexron iii, and others who have mercon licenses for mercon fluids.

This fluid is responsible for thoroughly lubricating the transmission and compresses the clutch packs to shift gears correctly. Thanks to the properties of the automatic transmission fluid help to generate speed changes with total accuracy. Valvoline claims to have an excellent mercon sp for multi-vehicle ATF. Yet, the same fluid is not the correct fluid for every transmission filter. Llc dba internet brands are not fit with every vehicle manufacturer.

However, vehicles of different models have different designs. That is why there is both Mercon V and Mercon LV. Choosing the proper fluid for your vehicle will protect moving parts, reduce wear and extend service life.

The maintenance of an automatic transmission is essential because the type of use that is given to the vehicle will affect the operation of the same if it is aggressive driving, the transmission fluid can be shortened, on the other hand, if the type of driving is standard, its liquid can be preserved over time. Among the google search threads, you can get mercon iii, lv fluid, motor oil, trans fluid, or whatever you need to improve your vehicle’s performance.

Generally, the fluid change should be done every two years; it all depends on the type of transmission your vehicle has. If the change is not done on time, it can generate excessive heating in the transmission, which is caused by contamination of the liquid and could eventually break the transmission.
