Hello to Forest Lucas and the whole Lucas Oil Family, Last week in Michigan Dec. 2007 we had a large snow storm ( 10 inchs of snow ) At 2:00 AM Sat. night my salt truck operator called to tell me the salt truck power steering went out and was leaking oil faster then he could put fluid into it, a quart every 5 mins. I had him try using motor oil but it was still was pouring out and the truck was going to be out of service and this was at the start of the storm, we needed the truck available for the next 5-7 days 24 hours a day. My operator said way don't we put Lucas Power Steering Stop Leak in it, to which I replied no way could it stop this leak, it's pouring out. Then I started thinking Lucas Oil has been around a long time and has grow into a very large company and I see them at all the circle track and drag racing events, and they have a money back guarantee, what can it hurt to try their product. Well I'm here to tell you I am now a firm believer in Lucas Oil Products they deliver what they say. The leak went down to using a quart every two or three hours and we finished all of our work for the next 5 days, and we now are changing out the power steering gear box, the main shaft is 15 years old and pitted, which is what caused the seal to go out. Your product is worth far more than you are charging for it. Thanks again and will see you at the races, good luck. Jon Shelton New Boston, Michigan
