Review: Arrived quickly thanks.
Review: If you’ve got a 10-16 D-MAX, you should already know the situation with the CP4 fuel pump. The diesel in the U.S. doesn’t have the lube in it like the old days due to emissions. The fuel is too dry and the pumps are “Grenading” on people. I use a lot of Hot Shot’s Secret products on my truck without any issues. I mix this with the HSS Everyday Diesel additive at every fill up. It’s a phenomenal product and well worth every penny you spend on it. If you have any questions, contact HSS website and it will get you where you need to be for an answer. I’ll keep using this until something better comes along. Until then, best of luck. T.H.

## 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!

*by T***. on 12 February 2024*

My 2001 Silverado HD has a 100% stock 6.6L LB7 turbo diesel, manufactured before ULSD regulations were promulgated for the United States in year 2007. For years, my engine has had an idle lope, and which recently upon fill up at a Chevron-branded station became more pronounced and was accompanied with a steady blue smoke plume from the exhaust. I suspected that the fuel pressure regulator was not moving smoothly enough and causing the fuel rail pressure to bounce around outside of target values. Since ULSD does not have the lubrication properties of pre-ULSD fuel, I wanted to try a lubricity additive, beyond the Power Service Diesel Kleen I have used since day 1. So I bought a bottle of this Hot Shot's Secret LX4 Lubricity Extreme, and added 5 ounces to my 34 gallon fuel tank that was full. I allowed it to sit overnight, and ran the truck in park for 10 minutes the first day, then let it soak again overnight. I ran it again for 10 minutes the next day in park, and let it sit overnight. The third day I drove it. The surge was totally gone and replaced with a beautiful smooth steady idle, and the blue tailpipe smoke was also gone. The exhaust from the tailpipe is now totally invisible. It's my belief that the pre-2007 Duramax engines were not engineered for the lower lubricity of modern diesel fuel, and for me, this has product is a huge blessing. (I do think the major fuel manufacturers like Chevron are meeting formal lubricity standards, but not to the lubricity level that the Duramax design engineers had in mind in earlier years pre-2007). Unless something changes, I'll use it from now on in my Silverado. Terry Livingston, Mobile, AL
