Motorcraft Mercon V vs. Mercon LV – Ford Automatic Transmission Fluid

What Is Mercon LV Transmission Fluid?

Mercon LV is a premium automatic transmission fluid designed by Ford to replace Mercon V and meet the needs of modern automatic transmissions. If your vehicle calls for Mercon LV, you’ll want to make sure you use a fluid that meets the Ford Mercon LV specification.

What vehicles require a Mercon LV?

Many Ford, Lincoln, and Mercury vehicles built since 2005 specify the use of Mercon LV, including models like:

  • The Ford Explorer and Escape
  • The Lincoln Navigator and MKZ
  • The Mercury Mariner

What are the benefits of Mercon LV?

Mercon LV provides several advantages over conventional transmission fluids:

  • Improved oxidation resistance which helps prevent oil breakdown at high temperatures. This allows for longer fluid life and helps transmissions run cooler.
  • Enhanced friction durability for consistent shifting performance.
  • Excellent low-temperature properties for easier startups in cold weather.
  • Better protection against sludge and varnish formation. This helps keep transmissions clean and operating efficiently.

What fluids can substitute for Mercon LV?

If Mercon LV is unavailable, you can use a fluid that meets the Mercon V specification as a temporary replacement. However, for the best performance and to maintain your vehicle’s warranty, Ford recommends using a transmission fluid approved to the Mercon LV standard, such as:

  • Motorcraft Full Synthetic Automatic Transmission Fluid
  • Valvoline MaxLife Multi-Vehicle Automatic Transmission Fluid
  • Castrol Transmax Multi-Vehicle Automatic Transmission Fluid

Using a non-approved substitute fluid can affect shift quality and transmission durability. So whenever possible, stick with a Mercon LV-approved product. Your transmission will thank you!

Mercon LV Specifications and Properties

Mercon LV is a premium-quality automatic transmission fluid formulated by Ford to meet the demanding requirements of their newer transmissions. If you want to find an equivalent fluid, you’ll need to make sure it meets the same specs.

Mercon LV has a viscosity of 6.1 cSt at 100°C, so you want a fluid with a similar viscosity, around 6 cSt, to ensure proper flow and protection. It’s also designed for an operating temperature range of -40°C to 150°C, or -40°F to 300°F, so find a fluid with the same temperature range. Here Specifications

Mercon LV in Place of Mercon V

Can you use Mercon LV transmission fluid as a replacement for Mercon V? The short answer is yes, Mercon LV can be used as a replacement for Mercon V transmission fluid.

Mercon LV is the newer fluid specification that replaced Mercon V, and it is backward compatible in most cases.

However, there are a few things to keep in mind:

  • Check your vehicle’s owner’s manual first. It will specify exactly what types of transmission fluids are recommended for your specific vehicle make, model, and year. If Mercon LV is listed as an acceptable replacement for Mercon V, then you are good to go.
  • Mercon LV has a lower viscosity, so it may provide slightly different shifting characteristics. The difference is minor, but some drivers notice slightly smoother shifting with Mercon LV. Performance will not be impacted.
  • It is not compatible with some older Ford transmissions that call for Mercon or Mercon V. Again, check your manual. Using an incompatible fluid can damage your transmission.
  • For the best results, flush the transmission cooling system when switching between Mercon V and Mercon LV. This will remove any remaining Mercon V fluid and metal particulates, ensuring Mercon LV’s additives and conditioners can properly protect your transmission.
  • Mercon LV can typically be used for the life of the transmission without issue. However, some manufacturers may still recommend periodic fluid changes for maximum transmission longevity. Follow the recommendations in your owner’s manual.
