Harry Sisson uses Lucas Power Steering Stop Leak for 1990 Chevy 4x4 truck

Dear Lucas Oil,

My 1990 Chevy 4x4 truck had a power steering problem for all of the six years I've owned it. With the first start every morning, there was absolutely NO POWER ASSIST when turning the wheel to the right. Left turn was always fine, and all external components were in excellent condition. It could usually be "un-stuck" by quickly and firmly jerking the wheel to the right about six or eight times, until the winter temperatures arrived, and then even that trick stopped working. Then the only thing to do was to just use brute force to "man-handle" the right turns, until after several minutes of driving and it began working on it's own. It was sometimes a little nerve-wracking when it decided to "un-stick" about half way through a "brute-forced" right turn.

All repair shops figured the only solution was to replace the steering gear assembly, and the lowest price for just the part was $385.00. However the owner/manager of our local (excellent old name brand) front end alignment shop suggested that I try a power steering additive, before deciding to replace the gear assembly. Our local NAPA store has carried Lucas products for years, and each clerk I asked (including the store owner) had pretty much the same answer. "Well, we sure sell a lot of those Lucas products."

I bought a bottle of your power steering additive, siphoned out all of the fluid I could get out of the pump reservoir, and refilled the reservoir with Lucas. (approximately 2/3 of the bottle.)

I am here to tell you that your product COMPLETELY HEALED my power steering problem. It has performed perfectly ever since, and even this morning with a cold morning start of just below zero.
