John Dirk uses Lucas Power Steering Stop Leak for Personal Vehicle

To whom it may concern,

I have been using your oil products ... most all of them for about one year. I am truly pleased with the result. I used your power steering additive in a leaking unit and within the first day the steering unit quit leaking and the vibration I have been experiencing was gone.

I also have been using your oil stabilizer and found that it reduced oil loss completely. It has allowed me to continue to use my transportation longer which is a savings to me in the long run.

Thanks again for great products that do what they say they do.

Sincerely yours,

John A. Dirk
