Michael uses Lucas Power Steering Stop Leak in1999 Mercury Cougar

I recently purchased a used 99 Cougar with about 84000 on the clock. After about a month the power steering started getting a little noisy and I noticed a few tight spots. I drained the power steering resevoir and added one bottle of Lucas power steering stop leak and within a few blocks of driving the problem was completely gone and hasn't returned. I have also started using Lucas injector cleaner monthly and have noticed my fuel economy improve by about 2.5 mpg average. Incedentally, I work at an auto parts store and recommend all you products to my customers on a daily basis.
