Alex Denysenko uses Lucas Oil products in NHRA/IHRA 65 Mustang

Recently we participated in the NHRA Carquest Nationals at Rt.66 Raceway in Joliet IL. We had some power steering difficulties with our tow vehicle and had heard about some magic elixir made by Lucas. We occasionally purchased some product from the Lucas Oil display as needed at previous NHRA events when required, but more often than not found that even as NHRA Lucas Oil Sportsman Racers, the prices we paid were considerably higher than through normal retail suppliers. Regardless, we were in a spot so we proceeded to the midway and your booth. We met a very nice gentleman who I unfortunately did not get his name. Mid 30's with glasses. As I was making our purchase I mentioned how typically we always paid more at the races than at NAPA for Lucas Oil products. He apologized, started to explain the marketing strategies, then stopped and gave us the product for free! I tried to pay him for it but he insisted that we take it complimentary and get our power steering fixed so we could tow home. End result is that we flushed the system, and installed your power steering additive along with fresh fluid and the power assist works as good as new. I just wanted to drop you a line to thank Lucas Oil and especially compliment your representative who was at the Joliet event for his exemplary racer customer service and attitude. We appreciate your support of the NHRA sportsman racers.
