About Hot Shot's Secret

Hot Shot's Secret is a Mount Gilead, Ohio-based brand that has built a devoted following among diesel enthusiasts, fleet operators, and everyday drivers who demand more from their engine chemistry. The brand was founded on a straightforward philosophy: deliver problem-specific, highly concentrated formulas that outperform the diluted products typically found on retail shelves. Every product is developed and manufactured in the USA, and each new formula goes through a rigorous three-phase testing process — beginning in the brand's own research and development lab, followed by independent third-party dynamometer testing, and finally validated through real-world use.

What truly sets Hot Shot's Secret apart is the science embedded in its formulations. Many of the brand's flagship products incorporate patented nano carbons and Group V high-performance esters — ingredients designed not just to protect engines, but to actively correct existing problems such as stiction buildup, failing injectors, lost power, and reduced fuel economy. This corrective-plus-protective approach has made Hot Shot's Secret one of the fastest-growing performance lubricant brands in the United States.

Fuel Additives

Hot Shot's Secret is perhaps best known for its extensive lineup of fuel additives. Products like Diesel Extreme and the Everyday Diesel Treatment (EDT) have become go-to solutions for owners of Cummins, Duramax, and Power Stroke diesel engines. Diesel Extreme is a fully concentrated fuel system cleaner engineered to remove both internal and external diesel injector deposits, boost cetane ratings, stabilize fuel, and demulsify water — all in a single treatment. The Everyday Diesel Treatment, widely regarded as the number-one diesel product in the US, is formulated for use at every fill-up, delivering cetane improvement, lubricity enhancement, and injector protection as routine maintenance. The brand also addresses seasonal challenges with products like EDT+ Winter Defense and Diesel Winter Anti-Gel, which protect fuel systems down to -40°F. Gasoline engine owners are not left out, with Gasoline Extreme offering similar injector-cleaning and lubricity benefits for gas-powered vehicles.

Oil Additives

Beyond the fuel system, Hot Shot's Secret offers a well-regarded range of oil additives built around the same concentrated-formula philosophy. The Stiction Eliminator targets the sticky residue — "stiction" — that can coat hydraulic injectors, oil pumps, and turbochargers in high-mileage diesel engines, cleaning them safely and restoring smooth operation. The FR3 Friction Reducer is a 100% synthetic oil additive that has been third-party ASTM tested to reduce engine wear by up to 43%, improve fuel economy by 5%, and increase horsepower by 5%. The TBN Booster rounds out the oil additive lineup by replenishing spent oil detergents and raising the Total Base Number of the oil, extending service life and protecting against acid buildup in diesel engines.

Fuel Additives & Storage Kits

For vehicle owners who need to store equipment seasonally or maintain fuel stability over long periods, Hot Shot's Secret also provides a range of fuel additives and storage kits. These products are especially valuable for off-road equipment, agricultural machinery, RVs, and boats that may sit idle for extended periods, ensuring fuel doesn't degrade and fuel systems stay protected between uses.

Why Trust Hot Shot's Secret?

Hot Shot's Secret backs its products with a straightforward performance guarantee — if the products don't deliver as promised, the brand offers a full refund. Combined with its transparent, science-backed approach to product development and a track record that extends from daily drivers to racing applications, Hot Shot's Secret has earned its reputation as a brand that diesel and gas engine owners can rely on.
