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.

Noticeable MPG boost for my F-250!

I’ve been using this Everyday Diesel Treatment in my F-250 for a while now, and the results are legit. The most impressive part is the improved fuel economy—I’m definitely getting more miles per gallon than before. The engine also sounds smoother and seems to have better throttle response. I love that this one-gallon jug treats so much fuel, making it a great value for the price. If you want to keep your fuel system clean and save some money at the pump, this is a must-have. Will definitely keep buying!

This stuff provides a smoother acceleration and overall effectiveness for the motor. With the added benefits of lubricating the fuel pump?

If you own a diesel engine, use this.

Size: 128 fl. oz, 1 Pack

For diesel owners looking to protect their fuel system, Hot Shot's Secret Everyday Diesel Treatment (EDT) is a heavy hitter in the world of additives. This 1-gallon jug is designed for the long haul, treating up to 1,280 gallons of fuel, which makes it incredibly cost-effective for daily drivers and fleet owners alike. The primary draw here is the 7-point cetane boost, which noticeably smooths out rough idles and improves cold starts. Beyond performance, it serves as a critical insurance policy against modern "dry" Ultra-Low Sulfur Diesel (ULSD) by adding essential lubricity to the fuel pump and injectors. It also features a demulsifier to help separate water from the fuel, preventing corrosion before it starts. While the 1-gallon bottle is bulky and requires a smaller dispenser for easy pouring at the pump, the peace of mind and improved MPG make it a staple for maintaining a healthy engine.
