Increases lubricity and helps protect fuel pumps and injectors. - Image 1](https://m.media-amazon.com/images/I/71EtRlPYiHL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Can lx4 be used in addition to a performance dose of edt to increase lubricity on a regular basis, and if so, what is the treat rate for 33 gallons?** A: Hot Shot's Secret LX4 Lubricity Extreme is designed to improve the lubricity of diesel and gasoline fuel, providing protection against wear and damage to fuel pumps and injectors. It can be used in addition to a performance dose of EDT to further increase lubricity on a regular basis. The treat rate for LX4 depends on the size of the fuel tank. For a 33-gallon tank, the recommended treat rate is 2 ounces of LX4 per tank. Simply pour the recommended amount of LX4 into the fuel tank before adding fuel. Be sure to shake the bottle well before use to ensure even distribution of the product. It's important to note that LX4 is not a substitute for EDT, which is designed to clean and maintain the fuel system. While LX4 can improve fuel lubricity, EDT is still necessary to keep the fuel system clean and operating efficiently. Therefore, it's recommended to use both products in conjunction with each other for optimal fuel system performance. **Q: does this clean at the same time like optilube? i dont see it stating that anywhere on their website or amazon** A: never heard of optilube so i could not say, all i can say is hotshot is by far the best diesel additive i have ever used, tryed many in the past no comparision to hot shot, im sure it helps to clean the fuel system, i get way more power when i use it, so its put in everytime i fill up. **Q: Has anyone found sediment in the bottle? When I recieved mine there seemed to be floaties then after settling there is whitish sediment at the bottom** A: Yes when it was cold out but I just shook it up and it cleared up **Q: Does this help prevent Gelling in colder weather?** A: No, it does not by itself. But please check out our Diesel Winter Anti-Gel specifically for colder weather, thanks! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Essential protection for my F-250 fuel system *by O***R on April 21, 2026* I’ve been running this LX4 Lubricity Extreme in my F-250 and it’s a total peace of mind.

Great stuff! ### ⭐⭐⭐⭐⭐ Best on the Market. *by P***E on June 7, 2026* I use this in all my diesel trucks and equipment never had a fuel issue ### ⭐⭐⭐⭐⭐ Perfect for my Ford Explorer 2013 *by E***S on May 21, 2025* I must say that I up keep my Explorer in everyway, oils changes on time religiously, coolant flush on time, all scheduled maintenance done on time, but I drive a lot of miles, 124 miles Monday through Friday, more when I have to pick up my daughter. So the wear and tear happens no matter the upkeep. Lately I've felt the car somewhat sluggish and I happen to fall upon this and read what it offers and decided to give it a shot based on the reviews. I must say that the difference was night and day, the car became more quiet, drove smoother, enhanced performance on the highway, it was a real noticeable difference. It just felt so much better when I put my foot on the pedal. Now with that said, I really didn't noticed better MPG, and maybe that was because I upkeep and baby this car. This was very simple to use, simply use 2 oz per fill up, you squeeze the bottle and it has a 1 ounce fill cup on the top of the bottle which is beyond helpful to make sure that you do not over use. I've driven over 2k miles since using this and I can assure you that it will not be a major part of my upkeep. ## Frequently Bought Together - Hot Shot's Secret LX4 Lubricity Extreme 32 Fl Oz Bottle, Clear, Yellow Liquid, (LX432Z) - Hot Shot's Secret Everyday Diesel Treatment 32oz, 6-in-1 Diesel Additive - Injector Cleaner, Fuel System Cleaner, Fuel Additive Boosts Cetane - Hot Shot's Secret Diesel Extreme, 1 Qt (Packaging May Vary) (P040432Z) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/174478651-lx4-lubricity-extreme-fuel-additive-32-oz-treats-320-gallons](https://www.desertcart.us/products/174478651-lx4-lubricity-extreme-fuel-additive-32-oz-treats-320-gallons) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-26*
