John VanBrocklin uses Lucas Power Steering Stop Leak for Personal Vehicle

To Whom It May Concern,

Hello, I wanted to write you a short note and thank you for producing such an outstanding product. I began by using your motor oil additive, and am now using it regularly in both my vehicles and my lawn equipment.

I work out of my vehicle on the road and average 125 miles per day, 5 days a week. I am confident that your product has substantially added to the life of my car's engine. I recently began feeling the transmission slip in the car, and immediately went to the store and bought a filter kit, some new fluid, and your transmission additive. The problem with the car's transmission disappeared immediately, and it is running great again.

I was very upset when the transmission in the car began to act up, because I have recently had to install a rebuilt transmission in my van, and I was not looking forward to having to do the job again on the car. Thankfully, replacing the fluid and filter in the transmission, and adding your products seems to have postponed that unwanted project for what I hope will be a very long time.

I have also tried your power steering additive in my van, and found that it works as you advertise.

It is very commendable in this day and age, to see products on the market that live up to their manufacturer's claims. I thank you for your products and wish you great success in the future. For your information, I usually purchase your products from Gillespie's Auto Service in Plant City, Florida.

Sincerely yours,

John F. Van Brocklin
