## 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!

### ⭐⭐⭐⭐⭐ 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.

### ⭐⭐⭐⭐⭐ Hotshots on the spot
*by T***9 on September 23, 2025*

AWSOME PRODUCT, CANT GO WRONG WITH HOTSHOTS

### ⭐⭐⭐⭐⭐ Seems great for an aged system especially
*by M***E on December 7, 2023*

My fuel injectors are 22 years old, and have received a lot of tlc to keep them going strong over the years. The fuel pump is not quite as old but could definitely benefit from this. I had it go bad once and it was a nightmare pump to replace, and pricey. I’m hoping this stuff will provide some cheap insurance. I love the company, they make some great products. This is simply a solvent free high quality oil. Ethanol removes lubricity from your fuel so this is a great way to replace it. After running it through the fuel system for a few hours, I’m noticing the engine runs a bit smoother at a slightly higher rpm at idle. I was also getting a recurring lean engine code intermittently that hasn’t come back since I started using this stuff, fingers crossed.Update: definite improvement in gas mileage! Went from 17mpg to over 20
