Hot Shot's SecretHot Shot's Secret Everyday Diesel Treatment 16 Ounce Squeeze Bottle (HSSEDT16ZS)

I use two ounces with every tank. Quiets the motor and seems to increase mileage slightly. I prefer this over Archoil and have it on subscribe and save.

Have a 2016 Ram 1500 Eco Diesel. The check engine light came on indicating below expected efficiency of a fuel injector. Added 2 ounces of the fuel additive and after driving about 50 miles the check engine light went out. Product worked great.

How did I go so long without this stuff. Fantastic! The DEF use reduction is crazy good!

BMW X6 diesel 3.0L. Last 3 month i was driving in heavy traffic condition. Average speed was 20 km/hour and since using this i manage to get it to only 13.7 l/100km. Very impressive

Can't say if it works. Have not noticed any increase in mileage. Can't look inside the engine to see if valves are clean. I do know, a little bit of this product goes a long way. I continue to use it until the bottle is empty. When I use a product, I like to see results with my eyes. So maybe or maybe not it's working.

Great product, but they really need to create a better cap for these bottles, along with something better for the foil seal when you open it for the first time. Leaks very easily and smells pretty bad when it does spill, and the messy foil can fall into the bottle and eventually into your tank if not careful. A simple screw on lid would do.

I use this every fill up
