Perfect Commercial

I enjoy advertising.  It tells me much about the research done by advertisers.  They want to tell a story tailored to their audience.  In my car I listen to channels on Sirius/Xm.  Apparently many truckers also listen to the same channels.  Often I hear ads directed to them.  One of my favorites is for Mobil Delvac's oils for diesel engines.  I know nothing about diesel engines.  But I know that if I had a truck with one,  I would use Mobil Delvac products.  I tried, but cannot find an audio of the ad that I consider the perfect commercial.  It is the voice of Rick Tanner, an independent owner/operator.  He has a wonderful slow southern drawl.  He loves the open road.   He loves the independence.  He had always wanted to drive, and has driven for many years.  After over 1 million miles on his engine, he rebuilt it, himself.  He uses Mobile Delvac.  He testifies that his bearings showed little wear.  He offers his view of life:  all you need for success is a clean engine and ambition.  Indeed.  Works for me.
