Kenneth Hoffses uses Lucas Power Steering Stop Leak for 1985 Buick

Dear Sir or Madam:

For years I have seen your product ad on TV. but could not find your products in my area. I am an auto mechanic for PEP Boys in Lindenhurst, NY. We now carry them. I drive a 1985 Buick with a rack & pinion in it, I thought for sure I would have to change. I tried your Power Steering Stop Leak for the rough spots and it worked right away. Thank you for making such a good product! I’ve seen a lot of additives that do nothing, so I could not believe how well yours works. I told a lot of friends and customers about Lucas Oil. It works!

Thank you sincerely,

Kenneth Hoffses
