Dear Forrest,

I just thought I'd write you a note letting you know about some of the things we have noticed using your oil products. When Walker Evans Racing and your company first made contact, I wondered just how good your merchandise could be. I had heard good reports from some people in the racing industry. However, I was still a little reluctant since your product was not as well known as others, and I wouldn't run any product that did not measure up to our teams' tough standards. With 177 team wins and 31 team championships to our credit, we have a reputation to live up to. I am happy to inform you that the extensive dyno and racing testing in our NASCAR Supertruck and CORR off-road series Chevrolets we have experienced an oil pressure increase, noticeable oil temperature decrease and wear characteristics that are far better since using your products (attributed to its ability to lubricate better). As you know, we have been using your transmission fluid, rear end oil and motor oil in our racing programs with great success and it doesn't stop there. We have been using your heavy-duty truck products in our eighteen-wheelers to get our race truck to all 42 race we attend each year. With all of the experience you have in the big truck market and the testing we ourselves have done, we expect continued success with Lucas Oil Products. Thank you for your high quality line of products.

Sincerely,

Kevin Kroyer
