Cody Burchett uses Lucas Oil Stabilizer in Factory Stock car

I started using your product in 01. What really sold me was when I started racing factory stock at Manzineta Speedway in Phx, AZ I had blown my good engine due too bad mechaning. I had another engine I had pulled out of a junked truck. I bolted on my good parts, stuck it in the car pored a bottle of lucas in with the oil. I started the car I had 50psi of oil, loaded the car an went to the track .The race started I lost all oil presure so I went for broke. I was black flaged for smoking to bad. Monday morning I took the car to work started the car to back it off the traler .I had 50psi of oil by the time I backed the car off I had 0psi. So I pulled the engine tore it apart. There was NO rodbearings at all. When I pulled the pistons all the rings were broke in half. This engine should have locked up. Thanks to Lucas I was able to save the block and heads. so I thank you for having such a great product.

Sincerely, Cody Burchett

PS I will all ways be a loyel customer.
