Omnitek Engineering Corp (OTCQB: OMTK) is an alternative fuel technology company that designs and sells diesel-to-natural gas engine conversion kits for commercial fleet operators. Revenue comes from selling conversion kits, individual replacement parts, and a high-pressure natural gas coalescent filter through a global network of distributors, dealers, and authorized installation centers. Omnitek does not perform installations directly; it trains dealers and sub-dealers worldwide to execute conversions using its technology, which centers on a patented fuel-mixing device and an electronic control unit. The company holds U.S. EPA approval for Navistar DT466E and DT530E engine models, a Certificate of Conformity for Mack E7, Detroit Diesel Series 60, and Caterpillar 3406E/C15 engines, and EURO VI certification from the European Union for its OT13 heavy-duty 13-liter natural gas engine. As of December 31, 2025, inventory on hand was approximately $296,132 against inventory reserves of $1,042,359, reflecting significant obsolescence pressure. The common stock trades on the OTCQB under the symbol OMTK, with a closing price of $0.01 as of April 7, 2026. No dividends have ever been paid.
