Robert Otto uses Lucas Transmission Fix for cargo van

Dear sir,

This letter is to tell you what a wonderful product your company stands behind. All to often a Company such as yours will get customer letters relating to some sort of complaint. This is quite contrary.

We own and operate a small expedited service business in the northeast part of the country, consisting of several cargo vans. Our vans run on average, approximately 100,000 miles per vehicle, per year. From the onset of the purchase of a vehicle, we have them serviced faithfully with Lucas products in both oil additives and transmission fix. As a matter of fact, not only is your product extraordinary in extending the life of a vehicle, I am writing to tell you that we have a van with over 500,000 miles on it's odometer and it's still going strong because of your products.

Enclosed please find a picture of the van that has one half million miles on it. I can't thank you enough for supplying a product to the general market that is so superior that I wouldn't think of having any of our vehicles go without it.

You may use this letter as a true testimonial of how anyone can extend the life of a vehicle with the help of your product.

Thank you again and keep

Robert F. Otto

Laceyville, PA.
