Lucas Oil 40011 Power Steering Stop Leak - 1 Litre

My Ford Focus had developed a slow power steering leak and a horrible whine every time I turned the wheel – especially at low speeds. I was fully expecting a costly repair job, but I decided to give this Lucas Oil Stop Leak a shot first… and I’m so glad I did! Poured it straight into the reservoir (no tools, no hassle), took the car for a spin, and within a couple of days the whining noise had almost completely gone. After a week, the leaking had stopped and the steering felt noticeably smoother. Honestly, this stuff is a lifesaver if your power steering’s on the way out. Great value, easy to use, and it genuinely works. Highly recommend giving it a go before paying for garage repairs – it gave my old Focus a second wind!

Great stuff. Maybe I got lucky, but I put the entire bottle in my honda accord. Seal up around the steering wheel had a leek. No More. Recommended, if you're leek isn't really bad.

This really did work well. Shame the engine didn’t last long enough for a true longevity test

Didn't reduce pump noise. Didn't stop leak. Not sure this does what it says it does and tempted to say, just repair the leak and use cheaper fluid!

Not had chance to use it yet but seems to be thick enough to do the job

I used two litres on a Golf 4. It does not work.

It's pretty thick, so I unscrewed the top and removed foil and carefully poored/squeezed in in up to fill line. Maybe use a funnel to avoid spills & have a cloth handy. Used most of the bottle over a week or so, leak reduced as did noise, steering was very stiff to start with, but fine after a min or so. Touch wood, leak has stopped, not had to add any fluid for a week or so. Nothing else has worked, tried 3 others.

Does what it says and can also be used in engines and gearboxes.
