Must buy!!
Extremely impressed! MPG improved from 10.8 to 20.2 in my 2019 Chevy Silverado 2500HD! My mileage is actually higher even towing a boat!

Great product in easy to use containers
I’ve been using Hot Shots EDT in my diesel truck for several years and love it. The easy-pour containers make dosing at each fill-up a breeze, and I’m confident it helps keep my engine as clean as a diesel can be. Reliable product I’ll keep buying.

Seems great to me
I dont even any studies or anything showing this product works great. All I can say is I've been using this on almost every single fill up since I bought my truck. I've had it for almost 7 years now. My truck has 190,000 miles now and I haven't ever had any issues with my fuel mileage, the Def system, or any other problems.

My truck told me it really loves this stuff!!! 😀
I recently began using this in my 2002 Silverado 3500 Duramax/Allison 4WD dually, with 145K miles on the odometer. I bought the truck new and have made quite a few modifications to it over time…Intake, straight exhaust, power programmers, etc. I’ve used other diesel fuel additives in the past with varying degrees of success, but none that really blew my socks off. 😂 Within a half tankful (15-20 gal) after adding this magic elixir, I have a very noticeable increase in throttle response, as well as a noticeable increase in smoothness when accelerating and I tend to accelerate a lot! 😉 I even feel that it starts a little easier. I can’t speak to whether I have any increase in fuel efficiency yet , but I’ll update in a few weeks, should I find any significant change. Needless to say, I’m sold! I will be consistently using this additive in “The Beast” for the foreseeable future! 😀 I can honestly, highly recommend this product!!! 😀

Great, but leaks
Would have given this 5 stars, however, if you plan on packing this in your truck, keep it straight up!!! If it tips at all, you will loose a lot of product, and it will stink. Great product, but they need to have a better seal on it!!!

Great diesel treatment for everyday use
I use this Hot Shot’s Secret Everyday Diesel Treatment for my diesel truck, and it has been a great product to keep on hand. The 1-gallon size is a good value because it treats a lot of fuel and makes it easy to use regularly. I like that it is made for everyday diesel maintenance, not just occasional use, and it gives me extra confidence that I am taking better care of the fuel system. A very practical product for diesel owners who want something reliable for regular use.

Added 2 to 3 MPG on my trip.
I recently used this in my Mercedes Sprinter van for a 3000 mile trip. Added to every fuel up. It increased 2 to 3 miles per gallon. I would have never believed it. I'm not sure it made it run any differently to notice but it definitely increased mileage. Very pleased with it and I will continue to use it.

Great diesel fuel additive
When we bought a diesel pusher, a friend of ours recommended this to us to add to the fuel every time you fill up. It doesn’t take much directions are on the bottle and we think it works great. We originally bought the smaller bottle which has an automatic pre-measure on it now we buy the big one to refill the small bottle as it is a much better value. Whether you have a diesel truck or a diesel RV, you can’t go wrong with this product… Helps to keep your engine running smoothly and keep your injectors clean.

Muy r comendado
Excelente producto, la única pega , es que el dosificador es en onzas/ galón. Siendo inútil en europa , que usamos el mililitros/ litros. Y el vendedor no se entera de la conversión. De todos modos os dejo la conversión 5 mililitros del aditivo / 10 litros de diésel.
