One of the standout features of LX4 is its ability to increase fuel lubricity by up to 56%. This is particularly beneficial for Ultra Low Sulfur Diesel (USLD) engines, which often suffer from insufficient lubrication.

LX4 is versatile and can be used in both gasoline and diesel engines. It’s easy to use—just add 1oz of LX4 for every 10 gallons of fuel. Many users have noted significant improvements in engine performance, including better gas mileage and smoother idling.

Customer reviews highlight the effectiveness of LX4 in various vehicles, from older models like the 1997 Ford F150 to newer ones like the 2022 F250. Users appreciate the noticeable difference in engine performance, especially during cold starts and high-speed driving.

However, some users have mentioned minor issues, such as receiving a container without a cap. Despite this, the overall feedback is overwhelmingly positive, with many users considering it an essential addition to their vehicle maintenance routine.

In conclusion, Hot Shot's Secret LX4 Lubricity Extreme is a reliable and effective solution for maintaining your vehicle's fuel system. Whether you're dealing with an older engine or a modern one, this product offers significant benefits that make it worth every penny.
