LX4 Lubricity Extreme is most effective when used with every fill up and is 100% compatible with other Hot Shot’s Secret fuel additives, including DIESEL EXTREME, EVERYDAY DIESEL TREATMENT and GASOLINE EXTREME. Follow recommended treat rates.
*Store above 32° F. If frozen, thaw, mix thoroughly, and use as directed. Although LX4 diesel lubricity additive does freeze at high temperatures, when mixed with diesel fuel, it does not affect the pour point, cold filter plugging point, or cloud point of the fuel.
TREAT RATIO
For pump diesel, treat rate is 1 ounce per 10 gallons to meet and exceed the EMA recommended 460 micron wear scar.
(For VP Racing Torq DX, treat rate is 1 ounce per 2 gallons to achieve a 461.5 micron wear scar.)

When the fuel our vehicles and equipment run lacks the proper lubrication, it can lead to catastrophic failures and expensive repairs. Fuel pumps and injectors are the most vulnerable when there is a lack of lubricity. Excess wear takes place, which can lead to mechanical failures and debris, such as metal shavings, being pushed through the fuel system. Hot Shot’s Secret LX4 Lubricity Extreme remedies the issues associated with low lubricity fuel by increasing lubricity and providing additional protection for all fuel systems.
Ultra-Low Sulfur Diesel (ULSD) has caused many issues and concerns for the owners of diesel powered vehicles. The process of removing the sulfur from diesel fuel also removes oxygen and nitrogen, all of which helped with the lubricity of the fuel. The lack of lubricity in the fuel causes all of the moving parts inside your fuel system to suffer, especially fuel pumps and injectors. The lack of lubricity causes excessive wear and eventually leads to failure. Hot Shot’s Secret LX4 Lubricity Extreme safely adds additional oxygen back into the fuel, which is not harmful to the environment. Lubricity is enhanced and the wear scar is reduced by up to 56% in the ASTM D-6079 method in un-additized ULSD fuel, exceeding the lubricity recommendation by the US Government and Engine Manufacturers Association. The use of LX4 Lubricity Extreme in your fuel system provides additional protection and leads to a longer life of your fuel system components, saving you from catastrophic and expensive failures.

How does LX4 improve diesel lubricity

The process of removing the sulfur from diesel fuel also removes oxygen and nitrogen, all of which helped with the lubricity of the fuel.

What Are Lubricity Additives?
Lubricity additives reduce wear on the fuel system including pumps and injectors. You need fuel lubricity for your engine to operate correctly and without breaking down. Lubricity additives return oxygen to the fuel, allowing it to go back to operating as intended.
Does Diesel Fuel Have Lubricant?
Diesel fuel has lubricant. However, removing sulfur from diesel fuel depletes it of oxygen and nitrogen. Both of these aid in lubrication, meaning wear and tear increases significantly when they are removed. An additive like LX4 Lubricity Extreme can restore the lubrication of diesel fuel.
Which Diesel Fuel Additive Has the Most Lubricity?
Hot Shot’s Secret ultra-low sulfur diesel (ULSD) additive, LX4 Lubricity Extreme, has the most lubricity available today. If you want an additive that performs at the highest level and adds the most lubricity back into your fuel, you should try LX4 Lubricity Extreme.
What Is Ultra-Low Sulfur Diesel?
Ultra-low sulfur diesel burns cleaner than previous types of diesel. Newer vehicles and machines are required to use ULSD. It was created for better emissions from the diesel combution process. Since removing the sulfur takes away some of the lubricity, you need an additive to restore it.
What Is the Best Additive for Ultra-Low Sulfur Diesel?
Our LX4 Lubricity Extreme additive is the best for ULSD fuel. Hot Shot’s Secret uses a specialized formula to increase lubrication in your fuel without harming the environment. Our additive also decreases the amount of wear on your machine’s fuel system.

Definitely the EDT if choosing between the two, as it now contains LX4 as a lubricity component. Hope that helps!

Just bought my GMC 3500 a couple months ago. Just started using the LX4 along with some of your other products. Since there has been problems with the CP-4 pump I wanted to give it some added lubricity and I look forward to using your products.

I will definitely start using this product. I have a 2020 RAM that died 9/23 on I-40 in OK. 15K miles and the pump shot craps on our way to Colorado for vacation. Not happy w/ RAM or CP4.
