Diesel fuel additives are a popular topic of discussion, with many people seeking to improve the lubricity of their diesel fuel. Ultra-Low Sulfur Diesel (ULSD) has been a particular concern for diesel vehicle owners as removing the sulfur from the fuel also removes oxygen and nitrogen, which are important for lubricity. This has led to an increase in the use of diesel fuel additives to restore lubricity and protect fuel systems. Hot Shot's Secret LX4 Lubricity Extreme is one such additive that claims to offer the highest level of lubricity performance on the market. Other popular additives include Marvel Mystery Oil, Schaeffer's Diesel Treat, and Opti-Lube XPD. While some people opt for dedicated additives, others use motor oils such as Howes MPK or two-cycle motor oil as a cheaper alternative.

What You'll Learn
Ultra-Low Sulfur Diesel (ULSD) additives
Ultra-Low Sulfur Diesel (ULSD) is a variant of traditional or "normal" diesel fuel that is mostly stripped of its sulfur content. The regulatory transition to ULSD use, which happened between 2006 and 2010, aimed to reduce diesel engines' harmful exhaust emissions and improve air quality. Sulfur is a natural part of the crude oil from which diesel fuel is refined and is one of the key causes of acid rain pollution when the SOx gases from combustion combine with water vapour in the atmosphere. Soot is the main component of diesel engines' noxious black exhaust fumes and is among the prime contributors to air pollution.
The process of removing sulfur from diesel fuel also removes oxygen and nitrogen, which help with the lubricity of the fuel. The lack of lubricity in the fuel causes all of the moving parts inside the fuel system to suffer, especially fuel pumps and injectors. This lack of lubricity causes excessive wear and can lead to mechanical failures and debris, such as metal shavings, being pushed through the fuel system.
To address the issue of reduced lubricity, fuel additives can be used. Hot Shot's Secret LX4 Lubricity Extreme is a premium lubricity additive for ULSD that can increase lubrication in fuel systems without harming the environment. It contains the highest level of lubricity performance on the market and can put even the poorest-quality fuel back into specification. It is also warranty safe and emissions equipment safe.
Other diesel fuel additives on the market include the STA-BIL Diesel Fuel Stabilizer and Performance Improver, Opti-Lube XPD All-Season Diesel Fuel Additive, and Star Tron Super Concentrated Diesel Formula.

Best budget options
If you're looking for a cost-effective diesel fuel lubricant, there are a few options to consider. Firstly, Schaeffer's Diesel Treat is a popular choice, offering both winter and summer formulas. It is known for its anti-gel properties, making it suitable for use in various vehicles, including tractors, diesel econoboxes, and motorhomes. Schaeffer's Diesel Treat is a good option for those seeking a bargain, although it may not be ideal for those seeking a comprehensive performance enhancer, as it lacks cetane boosters.
Another budget-friendly option is Diesel Extreme, which adds seven points to the diesel's cetane score, improving combustion performance. It also cleans and lubricates injectors and other critical fuel system components. Additionally, it helps remove excess water and contaminants from the fuel. However, Hot Shot's Secret does not recommend this formula for frequent, everyday use.
For those seeking an occasional deep-cleaning treatment, a small bottle of Diesel Extreme can work wonders in expelling buildup and improving fuel efficiency. It is also touted as an all-in-one product, including lubricants, stabilizers, and moisture dispersants.
If you're looking for an additive to improve lubricity, Opti-Lube XPD is a top-rated option. It enhances lubricity, boosts cetane, cleans injectors, and includes an anti-gel feature to keep fuel flowing down to -10°F. It is ideal for everyday use and is known to improve fuel economy and reduce emissions.
For ultra-low sulfur diesel (ULSD) vehicles, Hot Shot's Secret LX4 Lubricity Extreme is a good choice. It increases lubricity and provides additional protection for all fuel systems, preventing wear and scarring of key components. It is also warranty safe and emissions equipment safe.
Lastly, Seafoam is a good option for cleaning dirty fuel systems. Running a few tanks of diesel with Seafoam can help clear injectors, after which you can use a quality additive like Howes to maintain the system.

Popular diesel fuel supplements
Lubricity is an important factor in diesel fuel, as it helps to protect fuel system components like pumps and injectors from failure due to premature deterioration. Ultra-Low Sulfur Diesel (ULSD) burns cleaner than previous types of diesel, reducing emissions from the diesel combustion process. However, removing the sulfur also removes some of the lubricity, so an additive is needed to restore it.
LX4 Lubricity Extreme
Hot Shot's Secret LX4 Lubricity Extreme is a premium lubricity additive for ULSD and gasoline. It contains the highest level of lubricity performance on the market and can put even poor-quality fuel back into specification. It increases lubrication in your fuel without harming the environment and decreases wear on your machine's fuel system. It is also warranty safe and emissions equipment safe.
