Extreme Duty Marine SAE 20W-50 Engine Oil

Lucas Extreme Duty Marine SAE 20W-50 Engine Oil is designed for use in high performance boats requiring the ultimate protection.

It lowers oil temperatures, extends oil life and minimizes metal fatigue.

Twin Jalanugraha uses Lucas Power Steering Stop Leak in 1982 Benz 240D

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?)
