Hot Shot’s Secret Diesel Extreme


If you have been running your diesel engine for some time, you may have noticed the reduction in power and increased fuel consumption. The cause of the problems is soot that accumulates in your engine, especially on injectors, no matter what kind of diesel you use.

There are three solutions to the problem:

  • Cleaning using ultrasonic waves at the garage is expensive
  • Taking the injectors out and cleaning them yourself is cheap but needs knowledge
  • Diesel fuel additive that is the best option

When looking for diesel fuel additives, you may have come across Hot Shot’s Secret Diesel Extreme as the best additive but wondered what exactly it offers. This product is a preventative maintenance option, and alternative to DPF delete kits.

It contributes to reducing DPF regeneration cycles by up to 50%. Therefore, if your Regen stops working before you can get it fixed, this could likely save your truck from a hefty diesel particulate filter, diesel oxidation catalyst, exhaust gas recirculation valve, or selective catalyst reduction replacement costs.

Here is an in-depth review to give you everything you need to know about it.

What is the Hot Shot’s Secret Diesel Extreme?

DIESEL EXTREME is a thoroughly formulated, concentrated cleaner that removes all internal diesel injector deposits (IDIDs), including waxy and polymeric warranties.

Engineered with specific detergents, Diesel Extreme will safely remove and prevent Internal Diesel Injector Deposits (IDIDs), External Diesel Injector Deposits (EDID’s), and other forms of varnish. Deposits cause scaring and wear, which leads to premature failure of fuel system components, including fuel pumps and injectors.

By improving combustibility, this diesel fuel treatment reduces the number of diesel particulate filter (DPF) regeneration cycles needed. Diesel Extreme also contains a lubricity enhancer to reduce further wear, a water dispersant, rust and corrosion inhibitors, and a fuel stabilizer.
