Mercon LV vs. Mercon V Transmission Fluid: Overall Details

Mercon V: What is it?

Fluids with a high viscosity index, such as Mercon V, are used for automatic transmissions and power steering systems. The fluid usually flows but not rapidly due to its high index viscosity. Additionally, it is designed to protect against slippage in automatic transmission environments.

Mercon LV: What is it?

LV means low viscosity, meaning that the liquid moves quickly and easily. A 100% synthetic automatic transmission fluid, Mercon LV, marketed by Valvoline under the name Dexron VI, is made of high-quality materials. The Ford ATF is an upgraded version, and it cannot be used alongside Mercon fluids. Advanced additive technology is used to increase performance.


All Mercon fluids are incompatible with Mercon LV. Despite not being combined with Mercon V, Mercon LV can still be used with older GM Dexron on transmissions. This is because these transmissions require them to be customized to meet their demands.

In contrast, Mercon V is typically used for Ford automatic transmissions. Also, it has the same features as Dexron III. Additionally, it can be used with Type CJ fluid and Type H fluid.


As a lubricant, Mercon LV offers long service life along with superior abrasion and wear protection where needed.

For a wide range of industrial applications, MERCON V is the ideal hydraulic oil. Hydraulic oils that should meet ISO 46 or SAE 20W viscosity specifications. As well as being a premium-quality ATF, MERCON V is a good choice when it comes to power steering pumps.


Mercon has two products with different viscosity grades, which distinguishes the two. The Mercon LV is low viscosity & provides lower friction during engine operation. Engines are able to withstand instant heat, and it thickens in high temperatures. Compared to the Mercon V, this is a bit thicker.

Mercon V is an index that indicates high quality and stable viscosity levels. Mercon V is condensed to provide consistency, even at lower temperatures. It performs well at any temperature. This oil is especially suitable for the cold area since Mercon LV has a low viscosity.

Thinness and Thickness

Thinness and thickness is a very important part of any fluid brand. There is a difference in thickness between Mercon v and Mercon LV. There is also a variance between low and high temperatures. Mercon V fluid, therefore, prevents internal friction and abrasion more effectively than Mercon Lv fluid.

Overall Performance

Mercon LV further provides excellent transmission life and exceptional sludge resistance. This product also boasts excellent oxidative fixity regardless of the environment.

Compared to other fluids, Mercon V fluid ensures smooth gear shifting and prevents sticky mud and varnish from accumulating in the engine.

In addition, the engine will remain clean after prolonged use. Through comparing two popular products, you can easily determine which are the top products and decide whether or not they are alike or different.

Mercon LV vs. Mercon V Transmission Fluid: What’s the better?

In some categories and with similar specifications, we find a lot of similar products. When that happens, we are confused about what product is best and which one to purchase. We also compared these two high quality products in order to remove that confusion and worry.

They are both really better transmission fluids, so they belong to the same class as well.

As a result, you should consider vehicle compatibility, and requirements when choosing a fluid type.


Is Mercon LV and V the same?

A Ford automatic transmission fluid known as Mercon V is commonly used. In contrast, all Mercon fluids are incompatible with Mercon LV. Even though it cannot be combined with Mercon V, Mercon LV is still compatible with older GM Dexron transmissions since it is designed to meet the requirements of modern transmissions.

Is Mercon V transmission fluid synthetic?

Definitely, Mercon V is a completely synthetic automatic transmission fluid.

What is the difference between Mercon SP and LV?

There are two different lubricants, MERCON LV and MERCON SP. These lubricants are used in Ford vehicles that are very closely related. Particularly, SP fluid is used for Ford 6R60 transmissions and later Ford 6R80 transmissions, while LV fluid is used for late Ford 6R80 transmissions.

What is Mercon V compatible with?

Type H and Type CJ fluids can be replaced with Mercon, but Type F cannot. Late-model Fords use Mercon V ATF, which is similar to Dexron III. In transmissions requiring Ford Type F, this part should not be used. In 2008 and later Ford’s, this ATF was factory filled.

What happens if you put the wrong type of transmission fluid in your car?

GM’s Dexron series is the only fluid that can be used in automatic transmissions, and Toyota’s Type T fluid can be used in automatic transmissions. Incorrect fluid use can lead to improper overheating, lubrication, and also transmission failure. Even if the transmission is flushed, it might not be possible to repair the damage.

Final Verdict

As we conclude our discussion of Mercon LV Vs. Mercon V Transmission Fluid- the two are similar and different in many ways. Each transmission fluid is suitable for a particular sector and for a specific purpose. Mercon v has additional benefits compared to Mercon LV in some situations, even though both fluids perform well in some cases. Nevertheless, it is up to only you to make the decision which one to choose for the engine of your vehicle, since both have their own unique attributes.

The only difference is that each fluid is effective in its class regardless of which is best. In other words, depending on the compatibility, viscosity, and vehicle type, each fluid offers dependable and reliable performance.
