Hot Shot's Secret Everyday Diesel Treatment 16oz, 6-in-1 Diesel Additive - Injector Cleaner, Fuel System Cleaner, Fuel Additive Boosts Cetane

The best stuff for your fuel for diesel only. I use their other products as well for winter, etc. Worth your money IMO.

I was seeing a light puff of smoke from my farm tractor while accelerating .(sticky or dirty injector) After running one tank of fuel with Hot Shots Secret treatment white smoke is gone . Good stuff!!

D T C reading said 3 bad injectors, i added 2 oz. and before the tank was full, motor ran smooth. this is the only product that did what the label said it would do.

This product works so much better than lucas or howes I have found a large increase in power and since we live in North Dakota and it’s a tad chilly I haven’t had my fuel gel up once. I have been a huge Lucas fan for years but we always give other products a try once in awhile and this was worth it. I still use Lucas due to the cost difference but this is great for twice every three months to really clean things out.

Just bought a 2012 Cascadia with a cummins isx engine a month ago. Idle was rough and hesitated at first start. 3 tanks and three 16oz bottles later the idle has settled down and no hesitation on start. Smooth throttle response. Still too early on possibly reducing regens though. I will continue to add 16oz bottle with each tank refill of 195 gallons.

Hot Shot's is a great product. I use the everyday, fuel system cleaner, and just purchased Stiction. I have the newer RAM 6.7 Cummins. Some of the other diesel products throw codes if I use too much. Not with Hot Shot's. I do not use this for performance, but I can see a little more pick up. I use it to maintain a clean engine and parts. These are more expensive, but I think well worth it.

Had signs and could see i had a injector or two starting to get clogged/fail and doubled up on the EDT and 2 oz more than directed of the diesel extreme, they are starting to come back to life (first tank of this mix after full motor build) brought my mpg's up about .6 to 1.2, I recommend it to everyone that owns a diesel

This is a product that you don’t notice right away. It takes about 2-3 tanks before you notice an improvement. You really start to notice it when you no longer have any and you go a couple of tanks without it. Strongly recommend especially for those CP4 pumps. The lx4 in this product helps keep your fuel pump healthy and not self destroy

An excellent diesel additive to use at each fill up.

It’s a good product, very happy I got it.

Works great.
