--Focus on Accelerating Domestic Diesel-to-Natural Gas Truck Engine Conversions--

VISTA, CA – April 4, 2013 – Omnitek Engineering Corporation (OTCBB: OMTK) today announced the appointment of industry veteran Gordon Lilley as sales manager, a newly created position.

The appointment of a sales manager is an important strategic addition to our organization and addresses the significant pent-up demand for diesel-to-natural-gas truck engine conversions, particularly in the domestic market.  Demand has been greatly enhanced by recent EPA approval of our technology for the widely operated line of heavy-duty Navistar DT466E and DT530E engines, as well as plans to obtain EPA approval for additional diesel engines for conversion and other state-related certifications this year,” said Werner Funk, president and chief executive officer of Omnitek Engineering Corporation.

“Gordon’s extensive industry background and sales experience is intended to support the company’s growth in both domestic and foreign markets, and we look forward to his contributions,” Funk said.

Lilley, who will report directly to Werner Funk, most recently served as sales manager for Quantum Technologies. His sales and marketing experience during his more than 28-year career includes a variety of positions with companies across the United States and Canada, including World CMG, Impco Technologies, Navistar, Scelzi Industries, Ford Motor Company, Pickens Fuel Corporation and Gas Equipment Supplies.

He earned a Bachelor of Science degree in business administration and a minor in marketing from California State University at Los Angeles, California.
