Rennsli

What Rennsli does

Rennsli Corp is a privately held, Orem, Utah-based developer and manufacturer of fuel additive products built on a patented Fuel Borne Catalyst (FBC) chemistry platform. The technology, originated by Dr. Wesley Parish from solid-rocket-fuel research conducted for Thiokol and Hercules in the 1980s and protected by U.S. Patent No. 7,959,693, modifies the rate-determining step in hydrocarbon combustion to achieve more complete fuel burn, with claimed reductions in fuel consumption of up to 20%, particulate/smoke reductions of up to 80%, and Diesel Exhaust Fluid consumption reductions of up to 50%. The firm manufactures both liquid products (D-700, D-800, D-900, D-950) and quick-dissolve solid/tablet formats (DS-600i, DS-700i, DS-900i), plus consumer sub-brands FEROX and 801 Racing Pulse Power Boost, at a single facility with reported capacity to treat over 200 million liters of fuel per day.

Rennsli sells primarily to organizations operating centralized fueling fleets, including municipal and government fleets, commercial trucking and logistics operators, mining and heavy-construction firms, oil & gas and drilling companies, and industrial/commercial heating and marine end markets. Field-test reference customers include Walmart, Caterpillar, Astec Industries, Frontier Drilling, Yancey Brothers, Savage Industries, Hewitt Construction, Davis County Sheriff's Office, and Route 66 Logistics, spanning enterprise and government buyer profiles.

The company monetizes through direct one-time product sales via its website, email, and phone, Amazon marketplace sales, white-label/OEM supply arrangements with large chemical manufacturers and oil companies that face regulatory barriers to in-house production, and a channel reseller (CForth.com/Blaze Ecotech) following the September 2023 termination of its prior MLM distributor (Triformx/Xcelerate). Pricing is not publicly disclosed; products are concentrated at 1:5000 or 1:15 to 1:40 treat ratios, available in 1-gallon to 55-gallon liquid containers and in multi-gram tablet or powder pouches, with a clear multi-brand architecture aimed at industrial, consumer, and performance-automotive buyers.

Core offering

Rennsli develops, manufactures, and sells proprietary Advanced Fuel Catalyst additives in both liquid (D-900, D-700, D-800, D-950) and solid/tablet/powder (DS-900i, DS-600i, DS-700i) forms. The catalysts work at the molecular level to enable more complete fuel combustion, increasing power and efficiency while reducing carbon deposits, fuel consumption, and emissions across gasoline, diesel, HFO, ethanol, methanol, LPG, and LNG applications. Products are sold directly to industrial and municipal customers, through consumer channels (Amazon, FEROX, 801 Racing brands), and via white-label arrangements to large chemical manufacturers and oil companies.

Product overview

Rennsli manufactures Advanced Fuel Catalyst technology with patented combustion catalysts for improving fuel efficiency, power, and emissions reduction. The product portfolio consists of liquid formulations (D-900 Tier 4, D-700 Broad Spectrum, D-950 Winter Blend, D-800) and solid/powder formulations (DS-900i Tier 4, DS-600i Concentrated, DS-700i Multipurpose). Core consumer brands include FEROX (fuel catalyst in tablets/powder) and 801 Racing PULSE POWER BOOST (instant horsepower booster in solid ball form). All products share core nano-ingredients (Combustion Catalyst, Fuel Stabilizer, Corrosion Inhibitor) while liquid formulas additionally offer Lubricity Enhancer, Dispersant, Surfactant, and Anti-Gelling Agent properties. The technology is designed to work with all hydrocarbon fuels including gasoline, diesel, biofuels, kerosene, bunker, ethanol, methanol, LPG, LNG, and heavy fuel oil. Rennsli markets directly under the Rennsli label and offers white-label versions for municipalities and international customers.
