Hot Shot's SecretHot Shot's Secret Everyday Diesel Treatment 32oz, 6-in-1 Diesel Additive - Injector Cleaner, Fuel System Cleaner, Fuel Additive Boosts Cetane

I use this in my dump truck. It’s an 84 Ford L9000 tri axle with the Cummins M11. I try to do anything possible to stay on the road. I like the measurement cup that is built in. It does seem to help my old motor run a little smoother. I notice more of a change when I add 2 cups per 25 gallons personally.

Super surprised on how quiet my truck is now. I have a full header back 8” exhaust. When going through a drive through I don’t have to turn the truck off to hear the order speaker.

I use this in my LB7 and it runs amazing. I use this to keep the fuel lubricated and wouldn’t use any other product!

Several sites recommend today's diesel engines have a fuel additive for engine care and longevity. Other claims state increased fuel efficiency, but I have not seen this in my 6.6L engine.

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.

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!
