Diesel performance fans, strap in. Hot Shot’s Secret, already America’s fastest-growing diesel additive brand, just dropped Diesel Injector Flush, a powerful new game-changing weapon in the battle against injector performance loss.

Announced July 1, 2025, from its Mt. Gilead, Ohio base, Diesel Injector Flush is no ordinary additive. This concentrated high‑cetane blend tackles injector deposits head-on. These internal diesel injector deposits (IDIDs) cause rough idle, sluggish response, and fuel-economy drop, triggering trouble codes like P0263–P0278 and P1263–P1278.

So what makes this formula different? Hot Shot’s Secret dug deep into OEM bulletins and customer feedback. The result is a bulletproof cleaner that not only restores balance rates but does so quickly and safely, all while your engine runs.

An Oral Hygiene Analogy for Your Diesel System

Hot Shot’s Secret Brand Manager, Josh Steinmetz, puts it best:

If you think of your diesel fuel system like dental care, Everyday Diesel Treatment (EDT) is like brushing your teeth; Diesel Extreme is your regular dental cleaning, and Diesel Injector Flush is the oral surgeon. You’ll use it less frequently, but it’s critical to keep your injectors operating efficiently. In our testing the flush restored injector performance without replacement of an expensive injector and lots of shop time.

Numbers back up this bold claim. This flush goes deeper than Diesel Extreme, removing both internal and external deposits to revive spray patterns, timing, and balance rates.

When and How to Use Diesel Injector Flush

Hot Shot’s Secret recommends Diesel Injector Flush be introduced at fuel-filter change intervals or at the first signs of injector trouble. Look out for:

• Diagnostic trouble codes (P0263–P0278, P1263–P1278, for example)
• Misfires or rough idle
• Loss of power
• Slower throttle response
• Decreased fuel economy

Used proactively or reactively, Diesel Injector Flush helps reclaim lost horsepower and efficiency—and could save you a costly injector rebuild or replacement. As an added bonus, it can reduce DPF regeneration cycles, making it an easy win for longevity and maintenance.

Sizes for Every Rig

Whether you’re running a compact powerplant or a brute of an engine, Hot Shot’s Secret has you covered:

• 32-ounce bottle – perfect for pickups and smaller diesels
• 1-gallon jug – ideal for 8+‑liter engines, including medium-duty trucks, semi tractors, and heavy equipment
