Hot Shots

<h3>About Hot Shot's Secret</h3><p>Born out of a passion for solving real-world engine problems, <strong>Hot Shot's Secret</strong> has grown into one of the most trusted names in automotive chemistry. Manufactured in Mount Gilead, Ohio, by Lubrication Specialties, Inc. (LSI), the brand got its start in 2004 with the development of the Original Stiction Eliminator — a product initially created to address sticky injector friction in high-mileage diesel engines. Since then, the lineup has expanded dramatically, covering virtually every fluid system in a modern vehicle.</p><p>What sets Hot Shot's Secret apart from the competition is its commitment to concentrated, problem-specific chemistry. Rather than diluted, off-the-shelf formulations, many of their products incorporate patented nano carbons and Group V high-performance esters — compounds that don't just mask symptoms but actively correct underlying issues like injector deposits, oil varnish, and fuel system degradation.</p><h3>A Science-Driven Approach to Engine Care</h3><p>Every Hot Shot's Secret product is developed through an on-site research and development laboratory (LSI Labs), where the team works to translate lubrication science into practical, field-proven solutions. This &quot;Powered By Science&quot; philosophy means that claims are routinely backed by third-party testing rather than marketing alone. It's one of the reasons products like Diesel Extreme have earned recognition from outlets such as MotorTrend as a top diesel additive.</p><p>The brand's flagship <a href="/14704-hot-shots-fuel-additive-12140">fuel additives</a> — particularly the Everyday Diesel Treatment (EDT) and Diesel Extreme — form the backbone of their lineup. These highly concentrated diesel treatments clean injectors, boost cetane ratings, improve fuel economy, and protect the DPF system, making them popular with diesel truck owners, fleet operators, and enthusiasts alike. Seasonal products like EDT+ Winter Defense and Diesel Winter Anti-Gel round out the fuel care portfolio for cold-weather reliability.</p><p>Beyond fuel chemistry, Hot Shot's Secret has built an equally respected line of <a href="/14704-hot-shots-oil-additives-200733">oil additives</a>. The FR3 Friction Reducer, Stiction Eliminator, and TBN Booster each address specific threats to engine longevity — from microscopic surface wear to acid buildup in used motor oil. These products are designed to work alongside conventional and synthetic oils, not replace them, giving drivers an extra layer of protection between drain intervals.</p><p>Drivers looking after their automatic gearboxes will find Hot Shot's Secret equally well-equipped. Their <a href="/14652-automatic-transmission-fluid-additive-hot-shots-14704">automatic transmission fluid additive</a>, Shift Restore, is formulated to tackle transmission stiction, varnish, and sludge — restoring smoother shifts and reducing heat in both traditional automatic and CVT transmissions.</p><p>Rounding out the lineup are extended-life engine coolants and antifreeze engineered for both diesel and gasoline engines, offering superior corrosion resistance and compatibility with a wide range of cooling systems. And for those seeking a complete fuel system solution, Hot Shot's Secret also offers diesel fuel treatments designed to maintain fuel integrity, improve combustion efficiency, and protect against the shortcomings of modern ultra-low sulfur diesel.</p><h3>Trusted by Trucks, Fleets, and Racers</h3><p>Hot Shot's Secret has earned credibility not only on the highway but also on the racetrack, serving as the official oil, fuel, and additives sponsor of the Pro Pulling League. Whether you run a daily-driver pickup, a commercial fleet, or a high-performance competition rig, the brand offers targeted, scientifically validated solutions for keeping your engine running at its best.</p>
