I bought myself a little 1982 240D and just as expected from an old car, I kept filling up its power steering fluid. I went to PepBoy and saw one of your company's little oil additive gear-box and thought that may be your power steering stop leak may be as good. Well, just one bottle later, (actually 5 minutes later), it stopped leaking, and no more noises! Since one product works like magic, I started using your oil additive too. I encourage your sale staffs to put up those little plastic gear-box to show how well your product (oil additive) works. Without it, I might not have bought your product. (I saw it at Van Nuys's PepBoy store, near Costco store). But the last time I was there, the plastic gear-box was no longer there, may be someone from PepBoy removed it from the shelf? (May be your sale staffs can replace it?)
Sincerely,
